Lithium Battery Upgrade

i need a new battery for our 26ft tt, the old lead/acid rv/marine battery is virtually dead after 10 years of service.

is it worthwhile to upgrade to a 100 Ah li battery and the necessary new charger?

we do boondock occasionally and probably would do more with a better battery capacity. the old lead/acid battery was rarely adequete for more than one night boondocking running the usual lights, fridge and water heater controls.

Hi

If you live in the cold white north Li may become an issue.

You may not need a new charger. Be aware that battery management systems on LiFePo4 may limit demand to 1C. That may be an issue if there is a large inverter in use.

My next batteries will be SiO2 which can be charged at -40. But I do live where I boondock at -37 C. There is a Canadian Dealer.
