Lithium Batteries are 5 to 10 x cheaper than comparable Lead Acid batteries.
Lead Acid batteries can only use 30-50% of their stored energy.
They also have short life spans.
So they work out far more expensive over their lifetime.
The LiFePO4 chemistry of Lithium Batteries can be heated, cut, nailed & drilled with no explosions or flames.
We have chosen to use CALB LiFePO4 batteries on our own Boat and Camper Trailer.
