Why LiFePO4

Lithium iron phosphate vs. lead acid

According to Vanguard EnerG, compared with a lead-acid battery:

Cycle life

Up to 10×

Up to ten times longer cycle life and five times longer float/calendar life, minimizing replacement cost.

Weight

About 40%

About 40% of the weight of a comparable lead-acid battery: a drop-in replacement.

Power

2×

Delivers twice the power, even at a high discharge rate, while keeping high energy capacity.

Temperature

-20~60°C

Wide operating range. LiFePO4 chemistry removes the risk of explosion or combustion from impact, overcharge or short circuit.
