12V 4Ah Lithium Ion Battery — 12.8V Lightweight LiFePO4 Starter Battery, 1000-Cycle Life, ISO9001
This 12V 4Ah lithium-ion (LiFePO4) battery is a compact 12.8V starter power source designed for electric forklifts, motorcycles, scooters, and light electric vehicles requiring a lightweight, high-cycle-life replacement for traditional lead-acid starter batteries. With a 1000-cycle service life — roughly 3-5 times the cycle count of an equivalent lead-acid battery — and a 0.3kg package weight, this battery provides reliable starting power for applications where weight savings and maintenance-free operation are priorities. The 12.8V nominal voltage matches standard 12V electrical systems without requiring voltage converters or charging system modifications. ISO9001 certified with 1-year warranty, the battery is available in OEM/ODM configurations from MOQ 100 pieces. Applications include electric forklift starter circuits, motorcycle ignition, scooter power, and electric car auxiliary power systems.
Installing a lithium-ion battery in place of a lead-acid battery requires verifying the charging system compatibility — LiFePO4 batteries have a different charging voltage profile (14.2-14.6V absorption) compared to lead-acid (13.8-14.4V). Most modern alternators and chargers are compatible, but older equipment with unregulated charging systems may overcharge the lithium battery, reducing service life. The 3-4Ah capacity is suitable for starter applications where the battery provides a short high-current burst during engine start and is immediately recharged — it is not designed for deep-cycle or continuous discharge applications. For electric forklifts, confirm the battery tray dimensions and terminal type match before installation. The 1000-cycle rating assumes proper charging and avoidance of deep discharge below 10V. 1-year warranty covers manufacturing defects.
