Hello,
I recently installed an IP22 3 output 15 amp charger in my trailer. I am using the charger to charge three 70ah Lead Acid Deep Cycle batteries. I have attached a wiring diagram, I have the batteries and charger setup in this way as batteries two and three are also used in my caravan where they too are charged separately but used together.
When I have the charger on its standard settings for Lead Acid batteries it starts to boil the batteries during bulk charge. I have the charger now setup on custom settings to prevent this but this results in the batteries not being fully charged. The charger is set to 7.5 Amps and not 15 Amps, why would the charger boil the batteries during bulk charge? My 5 Amp CTEK charger never boiled the batteries, I'm sure a 2.5 Amp higher charge current would not cause this.
Regards
Charl
