Features
【Reliable Automotive Grade Lithium Battery】LiFePO4 battery has exceptional quality since they are manufactured by Automotive Grade LiFePO4 Cells with higher energy density, more stable performance & greater power. Highest-level safety based the battery and built-in BMS to protect it from overcharge, over-discharge, over current, and short circuit with excellent self-discharge rate. 100% safe, nontoxic, renewable energy.
【1/3 Lightweight & 2000+ Cycles】LiFePO4 battery is smaller and 1/3 the weight of the lead acid battery at the same capacity, which is convenient for you to remove and place it. Meanwhile, rechargeable battery provides 2000+ cycles compared with 200-500 cycles in lead acid battery.
【Outstanding Service】YouNatural is committed to providing you with satisfactory service. We also provide professional technical support and online customer service with quick feedback within 24 hrs.
