Description of LiFePO4 Battery
Lithium - lron - Phosphate (LiFePO4) battery offers a higher charge/discharge cycles, about 3,000 cycles at 100% DOD (depth of discharge). LiFePO4 cathode is intrinsically safer than the LiCo02 or the manganese cathode. We provides a complete line of 12, 24 and 48 volt batteries for use in RV' s, boats, EV' s and off-grid applications and much more. Our wide variety of standard and high performance batteries ensure we have what you need, when you need it.
