EXERGY EGP1278 Battery 12.8V 7.8Ah LiFePO4

EXERGY EGP1278 batteries are cells with a wide range of applications in various fields, e.g., electric bicycles, motorcycles, cars, buses, and trolleybuses. Made using lithium-iron-phosphate (LiFePO4) technology, which is much safer than others (does not cause a fire if the casing is damaged) and allows for 4,000 charge and discharge cycles. The terminals for connecting power cables are equipped with a T1 connector.

Key Advantages:

• Longer lifecycle compared to lead-acid batteries (approx. 4,000 cycles).

• Around 40% of the weight of a comparable lead-acid battery.

• Low self-discharge rate compared to lead-acid batteries.

• Multiple built-in protections (overcharge, over-discharge, and short circuit).

• Higher average energy efficiency (92%) compared to lead-acid batteries (80%).

• Application: photovoltaics, campers, boats, emergency lighting, electric vehicles and equipment.
