Overkill BMS - quick question regarding balancing

[Gould]

So here we are at the end of the day, floating, and things a lot closer. Dunno, will run like this through the weekend and see where we land next week.

balancing on discharge has the potential to undo your top-balance unless care is taken.

Could you expand on this ?

Ever figure it out Gould?

I haven’t spent the time to top balance each cell independently but am planning to do so this winter. Ultimately I turned down my bulk state until the BMS stopped tripping high voltage. At the end of the day I can get them to 14.1 without them complaining so it worked for my needs.

That works - you aren't leaving much on the table with capacity that way it seems?

Haven’t had a problem with capacity yet but did go with as much solar as my poor roof could handle. Had a stint this summer with overcast weather for three days and could have pushed it to 5 or 6.
