Too late to top balance with BMS?

[kolek]

You want to top balance to 3.65 volts.

After putting into service, you can daily cycle to 3.45.

I'm not doubting you but could you please explain why it's better to top balance to 3.65V?
Seems like some people believe charging to 3.65V and letting the amps drop to zero is doing damage to the cells.

60 amp charger with some fat cables can get all cells together in parallel 3.400 - 3.500 zone fairly quick to assemble the battery.
I assume the JK has active balancing and will take care of the rest while in service.

Yep, I'm working on it. Thanks for the tip!

So that each cell gets full. Think of it as the same thing as equalizing cells in a lead acid battery.

Except with the lithium cells, you only do it once.

Do it however you want. If you want to top balance at 3.4, do that.

Guys, you were right. I switched from 18awg to 8awg wires, and now I'm charging at 17 amps. An increase of 13amps over what I was getting with the thin wires. Thanks to everyone for the advice.
