Grade A 3.2V 90Ah Deep Cycle LiFePO4 Battery Cells Lithium Rechargeable Battery with QR Code, Perfect for Boat, RV, Golf Cart, Solar System, UPS etc
Lithium offers several performance benefits versus its sealed lead acid (SLA) equivalent .
A lithium battery's capacity is independent from the discharge rate and provides constant power throughout it's discharge.
The degredation of a lithium battery at a high temperature is significantly reduced in comparison to SLA.
Lithium has ten times the cycle life as SLA at room temperature.Even at an elevated temperature, lithium still has increased cycle life.
