You can easily and for a lot less money make your LifePO4 battery using 3.2v cells and a JBD BMS.
All of the steps for a beginner DIY to make a 24v 100ah battery.

I like seeing this kind of video where perfectly adequate systems can be made with many things not bought on Ebay for a fraction of the price, I made my buss bars with left over angled alloy for free working fine 4 years so far. Oxidization might be an issue so I might need to clean all the terminals periodically but otherwise all good. The amount of money saved can be vast when you diy it turning the financial viability around completely compared to buying off the shelf at 4x the price. Given how bent over my utility companies we are in many parts of the world this is a space where the difference it can make in your life is meaningful. So how did you come to the conclusion that compressing them isn't important enough to bother?......I don't want to use compression with my next build as it largely undoes the gains in energy densities increases over the last 5 years.

The first few batteries I made I compressed them. It just seems like a pain in the ass to do and i never saw any change in performance. I also don't have a way to accuracy or consistency apply a force and was never really clear exactly how many (N) was needed. That is purely my anecdotal experience and not based on rigorous scientific testing so I am sure others will disagree.

Yes the info provided is vague especially if its as important as some say it is, but until we see some long term testing we will never know. It looks like a lot of car packs dont put their batteries under compression.@@OurBlackCatCottage

@@OurBlackCatCottage yep, cells just came in. about to top balance. i see you went to 3.6 vs 3.65. is that just for safety or longevity reasons?

Deciding either by a 24v 100ah or build 24v 280ah for 100$ more im in tijuana so things are a lil bit more expensive

@OurBlackCatCottage 22 күн бұрын

Bigger is always better. Build that 280ah.

Hello would it be also possible to use 3.5 280Ah cells?

So if i want to build a 48v, would i just build 2 separate 24v and connect them in series?

@OurBlackCatCottage 5 ай бұрын

You could but actually I would suggest you look into just get a 16S BMS and making one 48v battery

@Brian-ri8pi 5 ай бұрын

@OurBlackCatCottage I love the idea of building one of these batteries especially if it's worth it but I'm not sure it is anymore for the price of the grade A cells I'm seeing. Lately I'm seeing some server rack 48v 100 ah batteries like aolithium for $1099. That's a good price and hard to justify the involvement of building a battery.

@JamesSmith-bj9vk Ай бұрын

If connected in parallel, would each battery require a BMS or just one?

@OurBlackCatCottage Ай бұрын

I am not sure what you mean. If you connect 8 cells in parallel you would still only have 3.2v and it wouldn't do you much good. Now every 24v battery you create from the 8 3.2v cells will need to have a BMS. Now if you created two 24v batteries, each with its own BMS you could then use them in parallel.

@@OurBlackCatCottage I'm only working with 12v but you get the idea. I'm wanting to build a 12v 100ah battery to connect to a Vaterer 12v 100ah which already has a 100a BMS. Some say yes and others say no. I really can't afford a BMS right now if I don't need it. Thanks!
