Im looking for a 'solution' on runng a lithium ion battery to run an engel fridge.
With substantially less weight and size 20Ah should run the fridge (max 2.75 amps usage) for 7 hours even 4 would be good. Once cold itholds for a while anyrate so I would be back inthe car. A solution producing greater than 3 amps would recharge the lithium battery faster?
Lithium ion should recharge faster than many other batteries apart from say a heavy deep cycle?
I would need look at both alternator & solar recharge of the lithium battery solution.
Have I my wires crossed?
Solved! Go to Solution.

If you charge or discharge lithium batteries too fast they can heat to the point of explosion.
They have a rateing on the battery that relates to the rate of charge/discharge.
This is independent of their ah rating.

lipo batteries with high charge/discharge rates (up to 20C) are sold by hobby stores for remote control model cars and planes. You will need a ready-built solution because lithium cells need a charge controller for each cell, they are very intolerant of overcharging, shorting, and being run too low.

I went to a Gel battery - thankyou!
