So I'm thinking it's about time to re-top balance my 4P4S pack... I mean it's been more than a year since I initially assembled this setup
I'm thinking what I could do to handle the rebalance without having to completely disassemble the pack would be to first bring it up to a high state of charge... Then disconnect it but leave the active balancer connected... Allow the act of balance her to bring everything into balance as best it can shouldn't really take more than an hour
Then disconnect the bussbars that go from one cell block to the next cell block to create a series connection
I could then go from positive of one cell block to positive of another cell block and do the same for the negative connecting all the cell blocks essentially creating a 16P battery
From there since it's already at a high state of charge it should not take two terribly long to balance it with my adjustable bench power supply
The problem is I'm going to be at a very diminished capacity and I live off this system...
So I really need to achieve this top balance in a fairly quick fashion
Let me know if this plan of attack makes sense
