42AH 12V Lithium Iron Phosphate Battery with 2000 Cycles and Built-in BMS for Solar Systems
Rechargeable lithium iron phosphate battery 12V for UPS system 42Ah
- Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and uses a non-aqueous electrolyte solution.
- Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
