The UPG LFP1260 uses LiFePO4 chemistry. The UPG LB1260 features a robust design that tolerates deep discharge and is suitable for all critical applications. This battery is suitable for as a drop-in replacement for VRLA and SLA batteries, and can use the same charger, provided that the voltage is limited to 14.6 VDC. The UPG LB1260 has a built-in Battery Management System that contains a low voltage Disconnect and a High Current Disconnect that are active on discharge. LFP batteries have an internal Battery Management System (BMS) which monitors the voltage, current and battery temperature of each cell in the LFP battery. If conditions are over the limits of the battery, the BMS will turn the battery off, similar to a circuit breaker in your house. The battery will turn itself back on when the conditions are within the battery parameters. While LFP batteries are more expensive than SLA batteries, the cost is reasonable if you are looking for longer cycle life and to save time through quick and easy charging.
