I have two batteries for my electric bike:
A 48 volt 15 amp hour ping battery and a 48 volt 20 amp hour calibike battery.
I live off-grid, and my only source of power is from solar panels and a 12 volt lead acid battery.
I bought a so called sine wave inverter with 2000watts of power.
When I plug in the chargers for both batteries, neither work, but make disturbing electrical noises, such as buzzing, popping and sizzling.
So, I have been making do by wiring 4 solar panels together in series to get about 60 volts to directly charge the batteries. So far, it seems to work, especially with the ping,as I can visually see when all the cells are balanced with the LED display and I unhook the battery.
I am hoping someone out there can recommend a charge controller/ or battery charger that will take a DC input of 12volt (so I can keep my panels in parallel) , step it up to a high enough voltage for my batteries and also shut off when the battery is charged.
Help me please! I am pretty frustrated..
