Charging issues

Typing at same time, it appears.


It may depend on how low "low battery" is defined. If it has to get to 12.6v to go to 14.4v the lithium may be holding it up that high even when mostly discharged.



I wonder if you can control two chargers off of one pendant so they could both be forced to 14.4v?

Thanks guys. Will keep you posted.

I have an Iota dumb charger set for 14.8 volts that I intend to test. It is only 55 amps but should be a good test if I can get 55 amps out of it. If I can’t make the PDs work then two 90 amp Iota chargers would be a solution.
