RB50 12V 50Ah LiFePO4 Battery PRICE: $656.95 This 12V 50Ah lithium ion phosphate battery is perfect in many applications, including marine and electronic vehicles. It maintains consistent power and is equipped with an M8 terminal type and a built-in battery management system (BMS). The RB50 battery meets UL, UN, CE and IEC certifications. All RELiON LiFePO4 batteries have installation flexibility, fast-charging capabilities and are maintenance free. Where maintaining water is never done because there is no water in these batteries, and the life expectancy is 10 to 12 years. They can be run clear down tell they stop. and recharge, or can be recharged any time you finish using them, there is no memory to worry about like lead acid batteries.
