I am interested in a BMS that is flexible allowing me to start with a 12 volt 4 cell and growing to at least a 24 volt 8 cell or staying in parallel with an 8 cell 12 volt setup. I started reading about the Overkill BMS and it seems like I have to know what my setup will be to buy one. I also think there are some that have integrated chargers, is that right? I have my eye on a Valence 138 amp hr used battery and have ordered a couple of cheap batteries to try out. If the cheap ones are not usable I can repurpose them to other DIY projects. Any advice or suggestions would be greatly appreciated. FYI, my first foray into backup systems is an EcoFlow Delta Mini which I got a really good deal on, so I will be using the batteries for solar and for extended outage protection to backup the EcoFlow. Thanks for any help!
