This might result in the LFP battery never reaching it's full charge and thus lowering the performance.. CHARGING - A LiFePO4 charger is highly recommended since SLA chargers might not reach the optimal 14.4V-15V LiFePO4 charging voltage. WARRANTY - We stand by and believe in our products and think you should too! That's why we test all batteries before shipping and offer a 2 Year warranty. As a result, our lithium iron phosphate batteries have a lifespan of about 5 to 10 years. This is compared to a lead acid battery that only offers 200 ~ 500 cycles.
