Then the sells don't get so warm and it gives the cells a change to level out with volts. Remember the cells is stack in series and the only thing that keeps them in balance is the BMS. The BMS shifts millivolts around when the cells getting full to keep them in balance, and sometime you get a cell that starts running away because of the resistant that is higher in it. Then it hits the Safety level that set on 3.55v or 3.65v and stops the charge. Some sells will not be full and this causes a unbalance in the sells. With my experience with Lifepo4 sells, they take charge volts really fast up, not like lead acid batteries. So you don't have to push a lot amps into them. Other thing I have learn and show some of the other guys is, when the lithium/lifepo4 unit getting close to to full "100% soc", it's a good thing to drop the amps low, like under 10amps, then the sells start balancing better out while they still busy charging. </blockquote>
