RoyPow 12V 18AH lithium iron phosphate (LiFePO4) deep cycle rechargeable battery

• 【3500~8000 CHARGING CYCLES】Premium Lithium Iron Phosphate Battery (LifePO4) Cells last long-time cycles. Battery capacity can reach to 80% after 1C charge and discharge under 100% DOD condition for 3,500 cycles. Its longer cycle life (up to 3500~8000 cycles) would be achieved under lower charge rate and discharge rate.
• 【BUILT-IN BMS & Low-temperature Charging Protection】Our powerful BUILT-IN BMS can automatically stop recharging under the temperature of 0 ℃ to protect the battery from damage. Also can prevent the LifePO4 battery from the most common issue causing of battery failure, such as temperature volatility, overcharge, over-discharge, over-current, overloading, overheating, ground faults
• 【GENERAL & WIDELY USE】 Allow to be extended up to 4 in series and 2 in parallel (Max 4S2P) to get more capacity (Max. 36Ah) and higher voltage (12V, 24V, 36V, 48V); Widely use in most areas such as: UPS backup, lighting (LED strip etc), digital/CCTV cameras, portable TV, e-Robot, electric vehicles (e-Bike, e-Robot, kid electric car), DIY loud speaker, 12V router, air pump, fish finder, golf car, trolling motor, motorhome / RV & camper, Houseboat, Travel Trailer, Dump Trailer and more
• 【LIGHTWEIGHT & VERSATILE】This LiFePO4 battery is only 30% weight of an equivalent lead-acid battery. With no acid in the battery, you're able to safely mount in any position. This makes Li-ion batteries perfect for marine, RV, campers, off-road and off-grid applications!
• 【2-YEAR WARRANTY & EXCELLENT CUSTOMER SERVICE】We have a professional customer service team, providing a strongly 2-year warranty, We are confident about our product quality since it has been strictly tested before shipping.
