Lithium batteries for camping fridge


Recommended Posts

Good day,

I have 12 x 3,2V 60A (192w/h) Lithium batteries which I connected in 3 blocks of 4 each to give me 12V for my camping fridge.

At this stage, I cannot afford state of the art dc-dc dual battery system. I guess I cannot push 100A direct from alternator with a manual switch?

Can I solar charge with a decent charge controller only or is MPPT advised?

Thanks for any input regarding....

As long as you can set the charge voltages you can use any solar charge controller (PWM or MPPT)

With PWM it does not work well if you join panels in series. Then MPPT is preferred.
So using 1 panel only, or only panels in parallel, then PWM is fine.
