More Information

18Ah Lithium Iron Phosphate battery from BSLBATT Lithium

The battery may look fairly similar to lead-acid batteries, but internally they’re a totally different (and much lighter). This 18.0Ah model can provide continuous current up to 18.0A with peaks of 30A. Absolutely perfect for high capacity portable power, and replacement of similar capacity lead-acid / AGM battery.

12v 18ah lithium battery

An internal battery management system (BMS) ensures all cells are uniformly charged and discharged, as well as providing short circuit, over-current, and reverse polarity protection. This provides you with a higher degree of protection than a traditional lead-acid battery which is unprotected and can discharge rapidly under short circuit conditions, causing fire and damage. The internal BMS will also limit discharge and manage cut-off voltage, to further protect the internal cells.

12v 18Ah Lithium Iron Phosphate(LiFePO4)Battery for Mobility Scooter, Electric Vehicles, Golf Trolley, Wheelchairs, Lawnmowers, Lights, Toy cars, Sprayers, Photovoltaics, Robots, Communications, Electric tools, Pumps, Measuring instruments, AGV (Automatic guided vehicle), Magnetic lifts. A high-end replacement for heavy users of Sealed lead-acid batteries. 

Lithium Iron Phosphate, LiFePO4 is changing the face of battery technology. They offer high rates of discharge, long life cycles, and are the safest lithium battery chemistry available. Long cycle life up to 2000 recycles, 8 times that of lead-acid battery, 3 times that of Ni-MH battery. Inherently safe, there’s no danger even if the battery is misused. lightweight up to 1/3 of lead-acid battery, 2/3 of Ni-MH battery. A small volume of less than half of lead-acid battery, smaller than Ni-MH battery. Low self-discharge, less than 5% after 6 months, good performance at high temperature, more than 70% capacitance remain after 1000 cycles at 45°C. It is environment friendly with no heavy metals or toxic material.
