I know this is more of an electricle vehicle/ebike forum, this is sorta off topic but batteries are still the same I guess.
I'm building a rover that needs 24v and at least 30A. Right now I'm using 2 of these battery packs in parallel for extra capacity.
Right now I'm taking the batteries outside for charging and keeping an eye on the voltages to make sure it doesn't over discharge while in use. However, I'm looking for a BMS that will allow me to just plug in a cable to charge the batteries and automatically make sure it doesn't go below the voltage cut off which is 3.2V for this battery pack.
I was told that this isn't a smart idea because the packs are in series first and then I'll put them in parallel, and I should do parallel first then series. I'm not sure if this is actually the case since I can still use the secondary cable to connect them in parallel, no?
If I cannot use the setup above, what's a better option?
I also found this battery pack which is overall less capacity but a single pack so no issues with parallel. I still need to find a BMS that fits my needs. Most of the ones I found are for li-ion cells where the cutoff is less than 3.0v.
