I have a multiplus 24/3000 that should be capable of charging at 70A. I have 3 200AH HE 24V batteries connected through a Lynx ION 400. Everything functions normally, but charging is topping out at about 42A. I've sent the max charge on the multi at 70A with a mk3 programmer. I've got a Cerbo GX /Touch 50 on it and I have tried with and without DVCC and within DVCC I've set the charge max to 70A and also turned that off and just tried to use battery voltage. But I never get the charge rate much above 40A regardless. Everything else seems to function normally. Discharge is fine at over 200A. firmware has all been updated, Not sure what else to adjust to get my other 40% of charge working. Thoughts?
