12.8V 100Ah LiFePO4 Battery – Lead Acid Battery Alternative
Description:
Our 12.8V 100Ah LiFePO4 battery is designed as a high‑performance lead acid battery alternative, providing longer lifespan, higher usable capacity, and improved safety for solar and off‑grid applications. It is widely used in solar energy storage systems, 1kW solar generators, RVs, campers, boats, and backup power systems.
Key Specifications:
– Nominal Voltage: 12.8V
– Nominal Capacity: 100Ah
– Energy: 1.28kWh
– Battery Chemistry: Lithium Iron Phosphate (LiFePO4)
– Cycle Life: 4000–6000 cycles @ 80% DOD
– Usable Depth of Discharge: up to 90–100%
– Communication (optional): Bluetooth / RS485
– Built‑in Smart BMS for full protection
Why It Is a True Lead Acid Battery Replacement
Compared with traditional AGM or GEL batteries, this LiFePO4 battery offers up to 3–5 times longer service life, stable voltage output, and much lighter weight. One 12.8V 100Ah LiFePO4 battery can effectively replace multiple lead acid batteries, reducing total system cost and maintenance.
Applications:
– Off‑grid and hybrid solar systems
– 1kW solar generator and portable power stations
– RV, camper, and marine energy storage
– Solar power systems for CCTV and telecom

Smart Battery Management System (BMS)
The integrated smart BMS protects the battery against over‑charge, over‑discharge, over‑current, short circuit, and high or low temperature. Cell balancing ensures consistent performance and extended battery life.
System Integration & Scalability
The battery supports series and parallel connection. For higher voltage systems, 25.6V or 51.2V battery configurations are recommended to reduce balancing time and improve system stability. This makes it suitable for PVHub‑based solar systems, hybrid inverters, and modular energy storage solutions.

I have pleasant experience buying from Shenzhen Suns. They shipped quickly, and very responsive and provided accurate updates. Shipment to Malaysia reaches in just a few weeks with a door to door delivery. Equipment work great, as can be seen from the photos, in the midst of installation and already in operation. The sales representative (Amy) has provided good knowledge and helpful to guide me to make the purchase correctly. Thank you Amy and thank you Shenzhen Suns and this company is highly recommended!
