From salvaging many 18650 packs, I found about 7 pouch cell packs that are about 4000mah 4S lithium packs.
I would like to connect them all together to make a simple UPS system for 12V. Each one have their own balance connector.
The question is, these would only be charged every once in a while and need to be more on a "storage" charge. How would you connect this up?
Connect all balance leads to one BMS? or individual BMS units for each 4S pack?
