Powertech 12.8V 25Ah Lithium Deep Cycle Battery SB2213

Next-generation LiFePO4 (Lithium Iron Phosphate) chemistry delivers significantly lighter weight than equivalent lead acid and AGM batteries. Internal Battery Management System (BMS) ensures uniform cell charging and discharging for maximum performance and longevity. BMS provides short circuit, over-current and reverse polarity protection, plus discharge limiting and cut-off voltage management to protect internal cells. Safer than unprotected lead acid batteries, which can discharge rapidly under short circuit conditions causing fire and damage. Robust 32650 LiFePO4 internal cells rated for 6,000 cycles at greater than 80% capacity retention. 10+ year service life expectancy. Ideal for high-capacity portable power applications and direct replacement of similar-capacity lead acid or AGM batteries. M5 bolt-down output terminals for a secure, low-resistance connection.
