Best batteries

Looking to replace the original batteries in our Pinnacle 5th wheel with Lithium. Recommendations?

Look for low and high temp protection, lithium can't charge below freezing and can't discharge below around 20F, if they don't have temp protection they will be damaged.

Look for a BMS (battery management system) that can accept the maximum charge and discharge that the battery is rated for, example, a 100AH battery should take 100A charge and 100A discharge. Cheaper batteries may use a lower rated BMS and thinner wiring that reduce allowable amps.

Bluetooth monitoring is a big plus, you can check state of charge, temperature, and many other parameters, even turn the battery on and off remotely with a good app.

I have 3 ReBel 100AH connected in Parallel. 2 years in they have been decent. Reasonably priced, and support has been good.
