Yes Grizzman, I'd agree with you, but a bunch of guys like Will keep saying that on a solar system although preferable, a bms is typically not required. You just need to do some additional maintenance every few months. This is my first exposure to a system like this. I've built 18650 packs in...
If you make two individual 4s1p packs, just leave balance wires attached to each and periodically check them by plugging in one of those little multi cell battery checkers. Just to be clear, I really don't know that much and am going by what I think is a good idea because other people have...
How do I bottom balance 4S2P LifePo4 battery pack? I purchased 8 used CALB CAM72 LifePO4 cells and would like to arrange them into a 12v 144A battery pack. All of this sounded like a good idea until I got to the thought of having to bottom balance. My thought was to put them all into series...
This question is keeping me up at night! Do LFP prismatic cells need to be confined with compression plates or do you want to leave space between cells so they can expand and contract? I've search all over and have found compelling arguments in both directions. I purchased used Calb Cam72...
Thanks for the great advice TCgreg! You reminded me of this little jem I had in my garage collecting dust (UltraPower UP120AC DUO) I used to use it for much smaller batteries. It has a discharge function, but I'm not sure if it is suitable for my size battery. It doesn't seem like there...
I'm trying to setup my tracer 4215BN using the MT50 to charge my LiFePO4. I'm using 8 cells in a 4S2P configuration, each rated at 72amps (when they were new) . I guess my main issue is that I'm not sure what alot of the settings mean and what values I should plug in. For instance: what is the...
I was getting ready to post the exact same question! Sorry to hijack... 4S2P (creating cell pairs, then wiring the cells in series) feels right, but I purchased my cell used I won't be able to monitor individual voltage to make sure I'm not over charging a single cell. Because of that I...
