[edit] Why would anyone buy these $300 batteries? Very simple - people buy the “small” batteries because they do not need 400Ah of capacity! If you only need 100-200Ah of capacity and you don’t have an unlimited budget, $300-600 hurts a lot less than $1500!

Hey Will, I bought one of these batteries about 6 months ago for my RV based on your first Weize video. I liked the quailty of the battery, the low temp protection and the great price. Battery has been good. I needed to replace my golf cart batteries so decided the Weize 100ah 12V would be a good choice. I bought three of them and run them in series for 36V. They do work fine but they do have an issue with the BMS shutting down current flow if I demand full output from the cart. It's rare that it happens so I'll live with it. Now that I saw you second video I'm second guessing my choice. Thanks for all the great info and videos.

Some of the reasons for buying the smaller 100 ah battery are for physical handling capability of the assembler. I’m very limited in the amount of weight I’m allowed to lift due to a spinal injury. So I’m looking to keep individual component weight down. Thus for people with limited physical ability and financial resources these tend to make sense.

That's a good point about the 12 volt sever rack battery. As I've said before our plan is to build an off grid property with a 500 to 700 SF home and use 12 or 24 volts for the lighting and a 48 volt inverter for the line voltage needs. Using two systems gives you a bit of redundancy in case something goes down.

The main advantages of the 100 amp hour batteries is current output for smaller systems and flexibility of where you can install them in a confined space like a boat or rv. If you aren't trying to run an air conditioner 200 to 300 amp hours is plenty of most rv and boat applications. With the 100 amp per battery you can still have a 2 or 3kw inventor and run loads like a microwave or induction hot plate. IMO the ideal for small systems is the 200 amp hour 200 amp bms from ampere time. Same current output as the 100 ah batteries with half the interbattery wiring and cheaper than even the budget eg4 server rack.

A prepper who puts a small system together might reason that four 100ah batteries is a safer bet since if one fails there are three good ones left.. whereas with one large rack mount a simple component might fail and take out the entire battery bank. ditto for multiple 100 watt solar panels instead of a single 360w panel.. a few small charge controllers instead of a single large one also might be a good choice... a video showing the benefit of such redundancy would be nice.

As an electrical engineer, it is standard procedure to have at least three manufacturers for every major component in your bill of materials. This practice goes on in everything from your TV to your car. An Infamous example I can remember is when GM had a manufacturer sell them a boatload of defective stepper motors for their instrument clusters, and they mixed them in with all the stepper motors from all the other suppliers, next thing you know everyone's gauges are randomly failing prematurely, while the majority go to 300,000 miles without an issue. Another well-known example is Apple not using the same speed SSDs or processors in various devices leading to "identical" devices performing differently on benchmarks. That being said, the important thing here is the company determines the minimum acceptable standard, the minimum acceptable performance, for Apple I'd imagine it's minimum requirements are still better than some fly-by-night Chinese company, even if they're manufactured in a factored across the street from the Apple products.

Charging with 30 cheap used 240w panels from Santan Solar (thank you for that tip too) and two Midnight Solar 150s limited to 90 amps each to keep the temps down. I did have them limited to 80 amps each before I installed a 10” fan plugged into a temperature relay to help stir the air a little.

I have three of the 50ah Weize batteries. One is used for a remote mobile camera that I move around my property. The other two I use for Christmas lights on either side of my driveway. I bring them in to charge. Mostly no sun in the winter. The mobile camera rig is just easier if I don't have to include a charge controller and a panel.

I bought this battery back when you first reviewed it, still works well. I bought 2 of the Ampere Time and liked them so I bought another 2. Reason I went with 4 12v is that I can reconfigure my set up in any voltage from 12 to 48 volts. If one of the batteries fails as a 12v system I only lose 100ah, for the other voltages it is a bit awkward to make it work but I will not be without any power as if it was a single 48v battery.

@fishhuntadventure Жыл бұрын

I follow that logic. Plus you can ‘scale up’ over time for budgetary reasons. Or just add one if a situation change needs a bit more amp hours without dropping $1500. Or for the two 140Ah Btrpower cheapos I bought for $395ea- I didn’t want to commit to more than 1 battery at first in case the brand was a dud. I tried to buy a third but they are not listing a 12V 140Ah any longer which is annoying. I get what you’re saying.

I appreciate your videos. Getting 100 amp hour batteries are good for people who are using a limited budget. I have 2 Battleborn GC3’s wired in series for my 24V system. Not knowing much at the time painted me in a corner. To increase my battery storage I’d need to buy two more batteries. It’s a $5000 bill I just can’t afford. I have a secondary 12V system with two SOK’s. To add storage, I only need to come up with $600.

Hi Will, Thank You for cutting open the first one and doing it yet again! The first video helped me a ton, it gave me the confidence to open the top on the one I bought in August of 2022. I put the battery into service shortly after receiving it without running any tests since I was not yet set up to do that. I ended up having some issues with the battery when charging and discharging in a solar setup I have with a couple 12v DC pumps. It seemed to disconnect during charging when it was close to but not at the cut off voltage. Then during discharging It would cut out earlier at a higher voltage than claimed. So I built a little setup to where I could discharge the battery at 20amps and keep track of the amp hours pulled. I then bought a Victron 5 amp charger which has the charge capacity built in with the app. With both I was getting a consistent 49-50ah discharge and charge. So I reached out to Weize through Amazon and to my surprise they responded to every email I sent and worked with me to finally refund some of my money to compensate for the 1/2 capacity battery. So once I received my refund I thought why don't I open it up and see if there is a cell disconnected (50ah 2p4s configuration) or something like that. What I determined was one of the paralleled 50ah packs was at a lower charge level then the other 3. I topped all of them off with a bench power supply and then ran my tests again. I now consistently get 98-99ah out of the battery. So not a perfect experience but I have to say Weize did respond usually within 24 hours and in the end refunded me some money so I am happy with it. My battery is built just like the battery you took apart in your first video, its unfortunate to see the lower build quality in the 2nd battery. Thanks again!

I bought a CHINS 300ah about a little over two years ago, the thing operates exactly as advertised still. I put it into a large camper van with a fairly large solar array, it limits charging to 60 amps, it has a hard cutoff at 200 amp draw within +/-3A. I learned a lot working with this, but the battery still works within spec at 99.5% original capacity I liked this so much, The next year, I bought the 400amp version for my folks home, who live off grid. better specs all around (charging/cutoff voltages that better match lead acid) no need for a quarterly drain down, even better relative short term current draw. The first battery showed up and was a dud, failed in a week, it retained capacity but couldn't deliver more than about 20 amps, I returned it for a new one, no issues since.

People use multiple 100Ah batteries because they start small and find out need to expand for the system to work as expected - like me, for example :) I ended up having 4 100Ah batteries and one 200Ah in a 12V system. All Redodo by the way. Nice video!

I bought three Weize 100A batteries from a vendor on eBay. One wouldn't charge properly, it wouldn't come up above 12V the charger would time out and after resting overnight it would show 9V . The vendor refunded me for one and didn't want the bad one back. I opened the case and found water damage inside. The B.M.S. had corrosion and under the heatsink the thermal paste was wet and runny. I bought another B.M.S. for $60 and soldered it in and repaired it.
