Deep Cycle Battery San Diego

Least Expensive 12 Volt Lithium Deep Cycle Battery - RV Application

An inexpensive battery option superior to lead batteries is the SB 12 volt 100Ah LFP

12 volt 100Ah Lithium deep cycle batteries can cost $1000 or more. The SB-12V-100Ah is a robust 12v LFP 100Ah (1280Wh) currently priced at $750 plus tax and with old battery exchange (lead acid)
Designed to be the least expensive and high quality lithium iron phosphate for installation in RV and trailers. MFG in USA

 

What is the Least Expensive LFP Battery?

LFP refers to lithium iron phosphate chemistry and 100Ah to battery capacity for deep cycling.
The small size of the SB 12V-100Ah is convenient as a  direct replacement of common RV & trailer 12v group 24 lead acid batteries. Both batteries are categorized as group 24 size and measure 10 1/8 " L x 6 5/8" thick and 9" tall.
Lead acid group 24 batteries start at $100 ea and last a few seasons. Group 24 lead acid AGM batteries can last longer but even the very best, still have a max cycle life of 1200 cycles to 50% depth of discharge and start at $200 ea.
The least expensive 12 volt lithium deep cycle battery, mfg in USA, currently would be the SB 12V-100Ah priced at $750 ea plus tax and with old battery exchange (lead acid) and a life of use anywhere between 2 and 5 thousand cycles, depending on the temperature, how fast the battery is charged and discharge, and charger quality (amps)
