Can I build a 4s battery with BMS, then charge the whole series with 30 amps from my mppt solar charge controller until I get one cell to about 3.55, then go to top balancing with the bench top PS? I want to do it this way, because I currently operate off a 100ah LiFePo4, and I cannot simply let a btps run for days. I expect the cells to be very well voltage matched when they arrive.
