I just received 24 304 Ah Eve cells and need to pre charge them before top balancing. I have two questions about the document that seems to be standard on this forum for DIY balancing:
Question 1
In step 3, why connect the leads together, max the voltage, and dial up the current while not attached to the batteries?
Question 2
Before connecting leads to the batteries why not:
1. Set the voltage as desired (29.2V in my case) and the current to 0
2. Connect leads to the battery
3. Dial up the current to desired amperage
It seems like that would prevent any kind of arcing.
Thanks for any insight.
