I bought 4- 280ah cells last weekend . This is my first and probably the last 12 volt batter pack built ,exciting! I’ve got a BMS on the way .and I bought a longwei dc power supply to top balance (on the way) . after measuring voltage here’s how they turned out . 2 of the cells came in at 3.303 volts and 2 came in at 3.301 volts . That’s really close ,do I still need to top balance ? The papers say max charge voltage is 3.65 . Thanks for your help !
