I'm afraid I have to disagree with the prismatic being better. Especially in an off road scenario. Cylindrical cells are wound tightly and encased in a metal casing, This minimizes electrode material from breaking up from mechanical vibrations, thermal cycling from charging and mechanical expansion. The complete opposite to prismatic construction ! Remember those Optima glass matt super tough off road starter batteries from the 90s? No coincidence each cell was constructed in a cylindrical manner.

Very unclear definition as there are several DIFFERENT Lithium battery technologies. Main known ones are LiPo and LiFePo. The former is used in phones, Electric cars etc as it has higher energy density. But also the known ,explosive fire, variety. It use allows smallest size for given energy capacity. The storage battery presented is LiFePo variety, where the far more stable, less fire prone technology is better, at small loss of energy capacity for given volume is of no concern. But for clarity this presentation should not refer to just 'Lithium' battery but state the technology specifics. Even the optimal charging is affected by Lithium technolgy used.

We just upgraded from AGM's to Lithiums by building our own battery bank on our sailboat (we liveaboard) using 180 amp hour, 3.6-volt CALB cells, and a DALY BMS, wiring the cells in a 4s2p orientation. So stoked on the upgrade! We charge our lithiums in 2 different ways. We send the power from our 120 amp Balmar alternator on our engine to our 100 amp-hour sealed lead-acid starter battery. From there a Renogy 60 amp DC-DC charger takes the load from the alternator and puts it in a lithium profile and in turn charges the lithium batteries. It was a fun build!

Great video and really helpful. The comment about Prismatic cells confused me as it conflicted with some other research I have done. What I have identified is that some manufacturers provide protection both in terms of physical (explosion proof jacket) and electrical (internal fuses) at a cell level. Prismatic cells are bigger and therefore both more dangerous in the case of explosion and cylinder cells. Cylindrical cells because there are more of them, have more redundancy at a cell level so a problem with a single is less likely to be as serious. So it may be more true to say that the quality of the cells used is more important, and a reflection of cost, than whether they are prismatic or cylinder.

You asked all the right questions, and Heiner answered very well. The first thing he answered well, was that the Lithium battery case is just a "housing" of the bits inside, so that case and how it looks is the thing that actually confuses everything...because if the look the same, then it should be the same, and that is where the issue starts. Lithiums are fantastic BUT you have to match and design it to work how you want, and unless you are technical at heart, you will struggle. You just started to touch on connecting multiple batteries at the end of the clip, and that is really when it gets complicated...if you need 24V or >200AH...then you really need to match and understand....whereas AGM's you can really still connect them in parallel and/or serial as you see fit, and when you need to...LifePo4 need planning. Great Video.

Interesting to see that AGMs (and FLAs) still "win" for certain applications such as under the hood of a car. Also, the guy wrongly said that a high current draw from an AGM battery lessens the capacity. That is not true. It doesn't significantly lessen the capacity of the battery, it just lessens the effective capacity of the battery at that higher amperage draw. For example, if a 100Ah rated AGM battery has 50Ah of usable energy (without damage to the battery) rated at the 20 hour drain rate, that means you can draw 2.5A for 20 hours to get 50Ah out of the battery (assuming a healthy fully charged battery). However if you instead put a 25A load on that same fully charged battery, then you wont get 2 hours @ 25A. You might only get 1.5 hours, but that doesn't mean the battery dropped to only 37.5 Ah usable energy. You can still extract the "missing" 12.5 Ah, just at a slower rate (such as the 2.5A rate). I suggest that draining the batteries either way (either 2.5A for 20 hours) or 25A for 1.5 hours, then 2.5A for 5 hours (both are 50Ah of drain), will leave the battery is a similar state of charge (around 50%). If you don't believe me, try it. I usually do capacity tests on batteries that way. I use a high drain rate until my inverter beeps (usually at 10.5V under load), then I lighten the load and keep going.

I’d never buy a battery based off 18650 cells. They don’t last and were never designed for this kind of application or for high discharge rates. My lithium can discharge at 250a constant (I have 2 under bonnet ) and rated for -20 to +80c temps and 3year full replacement warranty applies. This means I have 500a available for my winch, and that’s with the car turned off. My 200amp alternator can charge direct at 200amp to the battery no external bms so from flat to full is 1 hr. At idle I gain more charge in 30mins than solar could provide all day and I can run a 3000w invertor as well. Those cheap batteries can run a fridge and charge up some phones, camera batteries but lack the real performance. Cut them open and the bms is very basic and count the cells and they don’t match the claimed capacity

LiFePO4 is a rollercoaster in my present build decision making. Yes there is deep discharge and high cycle life ability, very high (95%) Watt-hour efficiency and superb energy density per kg . However, very few products seem to have a convincing CCA rating for emergency engine starting, most prohibit in-series use to make 24V without more complex BMS, charging and general use below 0 Deg C seems restricted to 5% Amps of Ah size and/or need for heating mats. My latest discovery switching me off again is risk of alternator burnout due to very high current even when charging at low rpm when alternator cooling fan performance is low, demanding alternator temperature controlled charge regulation. I'm rapidly concluding some low capacity CCA rated AGMs and a small homemade Honda GX35 24V APU charger generator is the way ahead to back up plenty of PV and possibly a yacht type wind charger . LiFePO looks great for domestic offgrid however.

The most important question and answer (for me!) was the very last one; "why 2x 100ah batteries v. 1x 200ah battery." To add to the electrical engineering answer Heiner gave, unlike AGM/Flooded batteries, you can easily add more batteries to the system later. That means you can start with 1x 100ah battery + DC/DC charger+charger/inverter+MPPT solar controller for your system and then after your cardiologist bills are paid due to the sticker shock, you can buy another 100ah lithium and add it into the system ;-)

ok, so i'm researching Lithium for off grid power for a home. what I feel makes a big difference is with AGM you should not discharge more than 30% - 50% often before recharging to conserve life. lithium you can cycle deeper to 80% + without shortening the life. now you can reduce your battery capacity by 1/2 for storage reasons. ie, I use 7Kw/day and would like to have 3 days storage before charging, hence with agm, I need a 70KW bank, with lithium, I can use a 35Kw bank. agm charge slowly, and at a rate of no more than 10% capacity, lithium is 30%. so far, lithium is winning for off grid for me.

I am totaly new to all of that but just been doing a lot of research on the DCDC chargers and the 1250D BCDC REDARC is my current choice though I wish it had some functions that the DCDC ENERDRIVE charger has - anyway- I am grateful you made this video as I have to go and get my whole battery management system checked over and ADD new batteries and a DCDC Charger since I had not run my Car for 3 years due to this stupid COVID crap and the Car was in Storage while I was stuck overseas- I was going to book VOLTAIC in Perth to do my upgrade and add new batteries ...but you seem to also have a lot of knowledge of maybe other good and reputable companies in Perth which you might want to recommend to me- I am certainly learning a lot lately and it is all a bit overwhelming to say the least LOL- Have a great day and safe travels always- Cheers

Lithium battery good for RV's, campers, running electric cars, motorcycles, trolling motors and golf carts. They are like deep cycle batteries that don't require constant charging while in use. Also, like the guy said, AGM battery can be on a constant charger and not hurt the battery. Lithium battery requires a special charger that shuts down the charging after the battery is fully charged.

you gonna love the lithium, enjoy. Surprised that your redarc jump started the management system. I have to jump start the management system on my batteries. I wonder if its because I have 2 75 amp batteries and you only had one for the test. Will be interesting to see once you have fitted both??? Maybe a follow up on this episode? or maybe its the relion management system vs the Amtron? As you saw on mine I have linked my started motor to the lithium batteries using a kill switch, so its hassle free to jump start both ways if needed.

Lithium Iron Phosphate cells (prismatic) batteries (like this one) are not as energy dense as some lithium chemistries but are essentially inert, so they are suited to situations where the size is less important, for example larger vehicles.

Any Radio Ham, who uses an ICOM IC-7000 transceiver, may like to know, that this radio can shut-down if the input voltage is less than ~12V DC. There are devices, that can boost voltage to slightly above 12V, to enable the radio to function, even if the input (to the boosting device) drops below 12V, but, this adds ~$100 to the total system cost... due to an ICOM design glitch, IMO. Worse (at least in AU): The case of an IC-7000 tends to run warm to hot, even in Receive-mode. I once sold an IC-7000, due to this "overheating" issue, when I was working in the Outback, in warmer seasons. Some warm days would "help" the radio to heat its case to temp's that we didn't want to touch!)

I think you can run a Lithium Batterie direct conected via BMS (Batterie Management System) to the alternator. As well as via solar charger and BMS. The BMS ( at least mine) will bring down the charging current to the amount the batterie wants. What do you think?

I’m currently running two fridges off two 100ah AGM batteries. 200ah AGM’s at 50% is 100Ah. So technically I can run my two fridges off one 100ah lithium as both systems give me 100ah. If I upgrade my charger from a redarc bcdc1225D to a 1240D this will increase the charge rate enabling the battery to be charged quicker making lithium the optimal system. Ampton states the optimal batter charge current rate is 20 to 50amps. Is this right?

So by the information you just have explained, if I want to use a lithium battery as my main power, then I should mount it some place else, other than the engine compartment. So that it could stay as cool as possible, away from any heat source. Or else it I do use it in the engine compartment, then I should install a cool ventilation system for the battery.

@@antonhofmann1796 So then it's 4x the life for lithium batteries when you compare to "super cheap" flooded ones. (If yours say "AGM2" that's probably a sneaky way of claiming to be AGM without technically breaking any laws. That would explain why they're so cheap.) IME lithium will last 4x as long as top grade AGM cells, and even then you can sell them at 80% of original capacity to get half your original investment back. Long story short, lead is cheaper up front, lithium is cheaper in the long run.

@@antonhofmann1796 I'm sorry but someone has been selling you a bill of goods. AGM isn't a different battery chemistry, it's a different construction method. The charge profile is no different, it's called "CCCV" standing for "constant current" and then "constant voltage". The initial charging on a mains charger can be constant current (so the voltage doesn't matter) to charge faster, then it switches to constant voltage when the battery nears full charge. In a car or 4x4 you only get constant voltage because the alternator is also connected to the electrical system, and that can only take a limited over-voltage. Newer cars with variable voltage alternators switch to a higher voltage of ~14.8V during charging, and back down to battery voltage to save gas. You don't need a different type of battery for these smart alternators, buy you may need a different battery isolator. If you have an AGM battery that's fine. You just don't get something for nothing. That lower price battery will probably not last as long as it could.

Was so close to getting lead crystal 18 months ago, went to AGM instead as i couldnt get the right size. At the time Lithium was 4 times the price of the AGM now that Lithium has come down would go that way. That being said have had no problem with the AGM setup very happy with it.
@sikandinc4 жыл бұрын
Newish AC chargers, such as the Noco genius family, now have the "force mode" where you can push current through when the battery has very low voltage/undetectable, which would happen in a lithium iron phosphate when the BMS goes into low voltage protection and the voltage sense at the terminals becomes ineffective. I bet future Dc-Dc chargers will also begin including this mode as an option if they haven't already.

A very good video Andrew, giving the average 12v electrical DIY 4wder punter a great explanation into the new frontier of Lithium batteries. It is a new technology that needs to be explained as the rules regarding capacity, charging, discharging, float charge etc of a AGM battery that we are all familar with...doesn't apply. The question I raise with your video...The connecting of several lithium batteries in paralell? 1/. Can this be done as some Lithium Manufacturers have said "within reason" providing the combined amount of Ahr of the batteries does not exceed the battery maximum discharge rate. An example...the maximum discharge rate of a single Lithium 100Ahr could as an example be 200Ahr...so you can parallel connect only two 100Ahr Lithium batteries. Some manufacturers...ie cheapie manufactured sub $600 Lithium...say no problem...they can parallel more than two batteries. Whilst other manufacturers have have flatly say NO...get a bigger capacity lithium battery. 2/. The thickness of the wiring needed for parallel connection is now debatable..it needs to be heavier...what type of heavy wiring and connectors? 3/. The age of the lithium batteries used. Example..all the lithium batteries connected in parallel need to be similar age and manufacturer..why? different BMS used by the manufactures. Could these questions be explained in the future.
@dupadupa58794 жыл бұрын
Peter, "in general" getting Lithium batteries connected in parallel is not an issue. But devil's in the details. There are conditions you/batteries should meet. All that is about batteries impedance. Less impedance battery will work harder both ways - charging/discharging. Therefore if you plan to have batteries in parallel it is fine but rather for more storage than ability to draw more current. You still can draw more current from them than from one but you need to bare in mind that any inequality in parameters of those batteries will work against them (and you!). If you have a need for more storage and casual need of drawing more than one can handle then having parallel set up is not an issue... UNDER CONDITION you will have exactly same model of battery and same age. So they will be as close to same as possible. In fact I'm using similar setup for 48V Li-Ion already.

I was talking to a company who specialises in mobile vehicle energy solutions and they sell AGM, Lithium and all manner of products from top manufacturers. They told me one of the downsides to Lithium was that many can not give as much current as a quality AGM and that as I have a 3000w Cotek inverter (identical to Redarc model) I would have to be careful as the Lithium battery could shut itself down if I tried to use too much power. That's pretty much the opposite to what your friend said in this video has has me wondering now.

Prismatic cells are not what prevents thermal runaway. Battery chemistry is the most important. This appears to be a lithium iron phosphate battery (LiFePO4 or LFP for short), which with a decent bms doesn't have thermal runaway like most lithium ion batteries. LFP batteries with prismatic or cylindrical cells are both good in vehicles.

After having Lithium for deep cycle battery for nearly 6months there is no going back to Agm in my main 4wd. 1. Lighter weight for same physical size. 2. As said about 100amp battery. Agm you get 50amp usage and maybe 1000cycles Li you get 80amp and 2000cycles. 3. The higher voltage of Li means less amps used 4. The quickness of recharging Lithum is main reason never going back to AGM in 4wd. Can charge at 1/4 of battery rating up to 95% capacity. So 100amp battery can take 25amps until 95% then goes to float charge. In 3 engine hours full battery with the right dcdc charger or if using solar to charge when sunlight is strong the battery usually accept all of the amps being produce and not shedding it as in agm charging cycle. If cycle between 30 and 70% charge it is in theory able to cycle 5000 times
