I've had semi good luck running numerous chargers in parallel. Zivan, EVWerks, KingPan, Elcon. As I understand, you should run no more than one not isolated charger. I've run as many as many as four chargers at a time; only my EVWerks is not isolated. I've "blown up" a number of KingPans and one or two Elcons so running in parallel could be a factor. Also, I've found my Zivan does not reliably register charge on my TBS meter if used by it's self; all other chargers register expected charge rates, individually and in groups. Of course, you need to be sure both your input and output wiring is up to the job. As well as your BMS relay. -- Willie, ONWARD!
