I was looking for the charge controller section but I could not find it.
I am building a portable little solar system with a Custom built Lithium battery (50ah cells) 12V Daly BMS.
Lithium seems to charge at whatever the max current is you can supply, greedy! So I would need to limit the charge rate.
All the PWM controllers I looked at seem to be aimed at LA & Gel deep cycle.
I am looking for a cheap’ish PWM (R500 - R1000) charge controller that allows me to limit the current output to a specified value. 20A should be sufficient ( I should be able to charge safely at 0.5C )
Something that I can get locally in South Africa, and output should not have any ugly spikes that could damage my BMS
- The idea is to charge via mains PSU - maybe an old computer 12V PSU
- Charge from a solar panel when out in the bush
- Charge from the alternator of a running vehicle if it is cloudy, I do not want to bun out the alternator
