The more I study the issue of building a battery bank & balancing the cells the more confusing it gets.
I have EVE 3.2v 280ah Grade-A cells, 16s-48v
Just watched 2 videos where Will says to bottom balance the cells for most home solar systems.
They were from 4 years ago, has something changed.
I top balanced the cells & had no problems at higher voltages cells stayed within 15mv.
But at lower voltage cells below 3.1v they started to get out of balance a lot, almost 100mv.
Which is best, top or bottom balance?
