[RE-wrenches] Lithium battery charge rate

[Jay]

Hi All

I’m wondering if minimum charge amps for lithium is common or not?

Or does it have to do with the cell shape: cylindrical vs prismatic vs pouch?

A client purchased some EG4 batteries and they are getting a bit out of balanced. Tech support didn’t suggest higher volts or longer absorb but did mention they need 30-50 amps charge. It’s not in the manual. 

Wondering what you all think and know

Thx
Jay
