I want to give HUGE kudo's to Trophy batteries! I got 6x batteries based on Will's previous videos and after talking with Dan. My batteries were shipped and unfortunately 2 of them were damaged in shipping. He was already coming my way and Dan literally drove 8 hours in his personal vehicle (2 hours out of his way each way) and hand delivered replacement batteries to me! I was blown away by this level of customer service. Absolutely, hands down the best customer service in my entire life!!! Cannot say enough good things about this company. Give them a look and based on my experience, I am sure you won't be disappointed!

I have had 6 of these for almost a year. They have been amazing in my unheated shed in the mountains. I've had some issues with remote monitoring/comms l, but Dan has been super responsive in helping me resolve it. I like that Trophy is just batteries and not trying to sell all kinds of other stuff.

I do small off grid installs for friends/relatives and your videos are the most comprehensive and easy to understand videos on the internet. Keep up the awesome work man.

"These are not flashy batteries, the do not have bright colours or bright logos." This is *_not_* a downside. 😀

I wish my wife looked at me the way Will looks at the guts of a server rack battery.

Great to see that you're still going strong! Checking out these batteries today... thanks!

These seem like a great deal, and alternative to some of the other server rack batteries. And I love that they go up to ~300 AH, as I think I could manage on just one of the 304 AH packs. Great info, great video Will!

It would be useful to hear more about the communications interfaces on these units and others. Getting battery states and charge/discharge rates into Home Assistant would be a must-have for me.

Absolutely agree with everything you said. I bought these. Completely happy. Dan is a really nice guy. My only wish is that the front switch was in the middle under the screen. The only reason is that I use a bus bar, and the switch gets in the way a bit. I would also like the terminal screws to be a half inch longer for my thicker bus bar. I don’t think that would be a problem for the way most people do it.

Bought the Trophy 48v 200ah last summer fir my RV. It's perfect!

Thanks Will. Nice overview. I do like the ability to replace cells if needed though. You did not mention Inverter comms compatibility with the Trophy BMS. Is it CAN or RS485, and Pylontec or other proprietary protocol? How do they handle load sharing when in parallel? That would be an interesting test. Would love to see them talking to your MPP LV6548's also!

Thanks Will. As always, your straightforward, in-depth review is much appreciated!

Those are maximum juicy! Love them. I like the singular approach of their company. Thx for sharing.

Hah, Dan @ Trophy sent you the pictures of my setup that you used in your video. Cool. As a FYI, those are five of the 304Ah Trophy batteries, which I built an insulated box around, as these are used in an unheated shed at 9300 feet altitude in the mountains of Colorado. So yes, it does get cold here. As for communication with Victron gear. So far Dan and I have not been able to get the 304Ah to talk to my Victron Cerbo GX unfortunately. As you said, indeed, Dan is just great to work with!

You always come across as a very informative and honest young man. ❤️

Great job on the pros and cons Will, I don’t think you know how much people depend on your knowledge and analysis, thank You!

Great video! We have three 100Ah Trophy batteries in our bus and love them. I accidentally had our first one shipped to our billing address in Minnesota while we were in Colorado and I didn't notice my mistake until the shipment was in transit. Dan took care of having it shipped to the correct address with the quickest customer service I've ever received.

THIS IS MOST LIKELY THE BEST SITE I HAVE FOUND ON THE INTERNET, GREAT JOB . KEEP UP THR GREAT JOB WILL.

One thing I do wish battery makers would do more are 12V batteries with the same features as these rack mounts: On off button, Pre-charge Resistors, built in SOC meters. I think EG4 has 1 that is 12V like this, but no one else. It would make creating small electricity back up systems SO much easier.

Thank you Will ,with honest assessment of all solar products.

Will, your words about Dan and his character not only speaks highly of yours...it was the only thing we needed to hear. Thanks.

I love how you just tell it like it is! Does the Trophy BMS communicate well with my Victron system?

Once again Will you have done it. What a great video. Thank you so much. I only wished I would of known this 5 years ago when I built my 24 volt system. Well now it just might be time to upgrade to a 48 volt system. I acquired another place in Southern Utah Near Lake Powell. So I am going to start planning a new system. Thank you again for all of your knowledge and help. You Rock

Damn those are great for the prices, love the competition coming out now. I already started with EG4 so I'll stick to those until I build a separate system (which seems inevitable as my needs grow)

Thanks every video I watch of yours is a learning experience since I have no idea what I am doing six stars brother

It’s adorable how excited he got when he opened it

Thanks. My hubby used echogear server racks (Amazon) for both of his systems.

You are too powerful ! Your mere word can crash vendors sites ! Thanks for the great video. I like simple. I like well built. I like heavy duty. I like doing something and never having to worry about it, never have to come back to it. Three of these on the floor and I'm done. Can't get easier.

As always a enjoyable articulate evaluation - Happy new Year Will - hope you have a gooden !

Great video as always. You are right with the fact that those batteries are underrated. I like the fact that they use higher capacity cells, then limit them to pull an intended capacity. That in my opinion puts less strain on the cells and make them last longer. Thanks Will.

Hey Merry Christmas, and I'd also like to wish you a wonderful New Year :) Thanks for the great videos!

Hi will thanks for your vids I am in the uk and find it hard for any self build kits that look like quality products i have found growatt and victron but the suppliers are very reluctant to sell any kits without the doing the install which is frustrating thanks again keep up the good work thanks jp

Fantastic, thank you Will for the review.

Hi Will! I’ve started to watch your videos a few months ago. Thanks a lot for your daily effort to bring us always new and relevant information! I’m from Portugal and most of the times my struggle is to find a vendor who ships to europe/Portugal. My goal is to design a system for my future house, that would use most of the time energy from photovoltaic panels / batteries to support all the loads and only get from grid the delta energy. So I would apreciate a video taking this in consideration.

I have been looking at different battery setups before buying. i already have a 6 Kw grid tie system. These Trophy batteries so far are the top of my list. The 10 year non-prorated warranty is a very good selling point. Also considering some of the better batteries are 48v 100ah at about $2400 compared to Trophy 48v 304ah at $4600. Which makes Trophy more economical.

Thank you so mch WTG, you're amazing as usual in what you do. For the last few years, I have been dealing with Discovery AES batteries. I really wish you could look into them. The only ones that can be flown on a plane and you can mount them upside down too, to make an easy connection with the next battery. 2,000 amp @ 24 Volt & 6,550 amp @ 48 volt. Thx Will, wishing you a wonderful new year.

One of the things I like about these is they're a standard rack unit height (the 220Ah one is 5RU according to their manual) and it looks like the mounting holes in the front panel are at standard spacing. Most of the other rack batteries AREN'T a standard size. It is a pity they aren't UL certified though.

🤓 OSHA Officer Killroy here: I would like to know where your tie off point was while on that table, How did you assess the table, where is your harness, when was harness inspected? By whom?....🤣😂 Another great video with most useful information, that's why I keep coming back, to see what's new and to see the pros and cons. Thanks again Will

I love the looks of the battery. Very clean.

Thanks for all of your hard work!

Happy New Year’s, solar panel guy🎉

Just wondering if the positive wire will block the screen on the smaller battery? Great video, I look forward to the max testing video.

I bought a Trophy battery specifically for the convenience of internal heaters. Note that the heaters are not manually operated. The heaters work automatically and only when charging power is available. The heaters do not operate on stored energy so they will not drain the battery. My battery is in an unheated shed and it has done pretty well as long as the sun cooperates. I actually used the crate it was shipped in as an insulated rack. The % state of charge does not seem accurate. I was at 39% and I plugged in my 500 watt block heater for my truck for an hour and a half and found the battery went into safe mode due to under voltage. By my math it should have had something left. It was -20F so I guess that had something to do with it. Also I haven't found a way to get it to communicate with my Growatt inverter, but it works OK as a dumb battery. It works fine and it has been idiot proof so far.

This is a great video! Would be even better to see how these batteries communicate with Victron Cerbo GX. Any plan to have a video talking about that?

Great review, keep them coming!

ha.. those 304's are the same KWH as my old chevy volt 2.. all in one container.. thats awesome.. thats alot of trons.. keep up the great work Will.

great vid will. Perfect timing of find this vid, we need to replace some 48v AGM 400a we have now. These will be out in a unheated shop inside insulated box. should still work.

wow you really take notice in your pool results :D

I think you for all of the great information on your channel

Awesome video with very good news, I will check them before buy an battery. 👍👍👍

I’d love to see you put together the ultimate used solar panel & battery system.

I bought the 220 AH Trophy Batteries. Happy

Hey Will, thanks for these insightful and inspiring videos. There's always something to learn! I am curious if there is any chance you can test/review the trendy lifepo4 blade cells. Looking forward to get your opinion on those.

Thanks , this great ,we appreciate your opinion again .

Thanks for all the info, Will. Would you do an updated video on the Titan? Any problems so far?

I've got several lfp batteries from different companies and also have experience with building with bare cells. I've started with cells and switched to pre-built rack/powerwalls but I'm starting to gravitate back towards the bare cells with a JBD 16S BMS that can work with (for example) Growatt inverters. It's so much cheaper at

Dan is my solar hero!

You talking about Dan . Dan seems like someone is older generation with skills instilled in him. Customer service , maybe a engineering degree and old school simplicity. He knows how to keep cost down ! Kinda reminds me of my dad in his business when people ask if he took PayPal , lol...He always did checks and wire transfers . Wait to see more on these batterie's.

I would buy computer system warehouse racks with adjustable sliders to get the 19" rack style mount. Typical is 42U.

I appreciate your content my man!

Thanks Will

Good job, and very good information.

Thanks Dan 💫

Thanks for the “Boring batteries” video. Thumbs up. Would you recommend which inverter or management system could go with this batteries?

I have 3 of the 100ah batteries. They are mounted in my unheated shed in northern lower Michigan.I have had these since June and my only issue is some sort of remote state of charge as I have an Outback system an have struggled with consistent automation of my generator (worked perfectly with my AGMs). I would love a video talking about options for remote state of charge as no one seems to want to give me suggestions. Through many phone calls it seems to be an issue not quite dealt with yet! These batteries are incredible!!!!

I might try these next go around right now im all signature solar.

Would love to see a Victron build along with these batteries. I wonder if there's any functionality loss to be expected.

Great info .. will they work / talk with Victron gear ?

I’d still like for you to take a look the pytes server rack batteries that Ian carries at watts247. I’m just curious what their guts look like.

Really nice build Quality.

Thanks for blowing the pricing

I prefer the DeWalt storage rack over a server rack. I find that the steel used on the bolt rails is too thin and you need to use a rack with rear rails as well. One needs to create a shelf between the front and rear supports and slide the packs onto the shelves. Get too high and you need to bolt the server rack to the floor and wall. You also need a safe lifting device to get packs into place.

Might want to update links, the sites working when you search for it but the links from your video are broken... Great video as always.

Do you ever try the communication ports? Would be interested in knowing if the communicate with a Victorian controller so it knows the state of charge and can provide the proper charging profile

Sup Will, just wondering if at a later date coving subjects like GFCI protection devices, SPD’s and wiring equipment. It’s not a very sexy topic I admit, but I’d love to hear your take on the subject at some point. Love the channel btw!

What brand of Inverter and charge controller do they work with? I am interested in if the work with EG4 and Victron Inverters and Charge controllers. Thanks for a great video

hi Will, please consider doing a review on the Mango Power e portable whole house backup system - it has gotten a lot of positive reviews from many KZfaq reviewers, but we would like to hear your honest and unbiased review.

Looks pretty nice.

Thanks, Wiil. I think it is a pro that there are are no flashy colors. Great information thanks so much.

I might have to look into these

Will, I use 4" long sections of electrical heat shrink tubing to protect disconnected battery cables. I tape up one end of the tube with electrical tape, leave one end open to slide in the lug. I use tubing that is a snug fit so it cannot just slide off. I figure if it is safe enough to use on electrical connections, it should be safe to use as insulation when disconnecting batteries.

Hi Will! I enjoy watching your videos about off-grid stuff, i JUST got my panels, inverter etc. installed, still have to setup Lan/wifi. Im just wondering if u have any recommendations of vendors on aliexpress that has grade A cells and overall good/decent quality. Keep up the good work man and would like to see some off-grid rv stuff.

If the only downside is they don’t look cool….. great video really informative as usual

This is like my 4th battery today, great content! Curious, have you found anyone that sells "Trophy Battery / Inverter" kits?

I have the same hat you are wearing in this video and I love that hat. It looks better on you but I still love that hat

Will, Trophy does have UL listed batteries now. Mark Durham

Hello Will, Love the videos, been watching for years. Thank you. Would you recommend a Trophy rack battery for van use? (w/ Victron inverter (with shore power switching a nd battery charging from mains)? also a Victron solar charge controller, with the 900watts of panels on the roof already? and how would you address charging from alternator when van is running? Would I be able to charge from an EV car charging station? thx again. Matt

Will, what's the hang up of connecting a Trophy battery to different inverters? Is there a communication issue?

Will these talk to the EG4 Inverters? I'm looking to build a backup power solar cart in the future, something to output about 3k VA for Freezers and Fridge and run the house off while the power is out. I like the option of the Heaters as well.

Thank you.

Around the 13min mark you state these are EV grade UL Listed but earlier I thought you said they were not UL listed which may prohibit grid interaction. Are you referring to the cells that are UL listed but the server rack units are not UL listed? Thanks (Awesome videos, keep up the great work)

Will, do you have any plans to review any of the new Ampere Time server rack batteries?

Hy Will, been watching and following your videos for past couple of years since I picked up an ista breeze heli 4.0kw turbine. Since then I've been gathering parts I thought I needed, starting with a 48v dc out 5kw turbine controller. I added a couple of hybrid powmr 5.5kw inverters to run in parallel mode with two seperate 48v 15kwh lithium batteries. I also have 10x450w bifacial panels which I intended to run in two strings, one to each inverter. I would love to hear your thoughts on connecting the 48v dc from turbine controller to the batteries which would be in parallel with the inverters. Powmr say that I will run into trouble...I had hoped to run the mppt charge points from the inverters marginally higher than the turbine controller battery settings. I could run the output from the turbine controller to a seperate inverter and run that AC to the parallel inverters as a "grid input" (system is for off-grid use). Great clear informative information on your channel, congrats

Can you please review the anker 767 powerhouse. It looks promising!

Will, what do you suggest for a circuit breaker with a normal on/off like those on the trophy system?

Hi Will... I really like the look of these type of batteries. I would like to get 3x 304Ah units for my setup or multiples of the other types perhaps. I have a three phase system here at home. I would love a video on how to run these in a three phase system. I was guessing that each phase would have a battery, and then have a balancing method in the backend, however there are likely inverters that might handle the loads by phase stuff. My loads are not perfectly balanced though the largest loads (AC 6kw, and EV 7kw charging) are native three phase so the major "problem loads" are good. I'd love to see your take on a three phase system (I am in Aus where we have 240v and 415v)

Great video as always! Thank you for making these. What would be good addition to your channel would be testing bigger 48 to 92 volt BMS's :)

Great video! Can you use these in rv or travel trailer?

Of course, this vid comes out AFTER I buy 4 EG4 batteries and 2 of their inverters from signature Solar. I wonder if 2 of these would be compatible with my Sig Sol stuff. Now I just have to figure what else I need and out how to put it all together.
