Rechargeable LiFePO4 battery NPP LFP12.8-8 — 12.8V 8Ah, T2 terminals

NPP LFP12.8-8 is a rechargeable LiFePO4 (lithium iron phosphate) battery with a nominal voltage of 12.8V and a nominal capacity of 8Ah (102Wh). Designed with T2/F2 (6.3 mm) terminals, this compact battery provides stable voltage, high usable capacity and improved safety compared with lead‑acid technology. Its internal intelligent BMS monitors and protects the cells to ensure reliable operation in small-scale energy storage, backup power and portable applications.

Advantages

LiFePO4 chemistry delivers up to 15 times longer cycle life and around five times longer float/calendar life than lead‑acid batteries. The battery can supply up to 100% usable energy, supports fast charging with about 99.5% charge efficiency at 0.2C (25°C), and shows low self‑discharge (≤3% per month at 25°C). It is approximately 60% lighter than equivalent lead‑acid units and supports high discharge rates with over 3,000 cycles at 100% depth of discharge. The built‑in intelligent BMS optimises performance and safety.

Suitable for

• Solar and wind energy storage
• High‑power inverters and UPS
• Data center auxiliary power and telecom equipment
• Emergency lighting
• Camping and portable power
• Small marine electronics such as fish finders

How to use

Install the battery on a stable, vibration‑reduced surface and connect using the provided T2/F2 (6.3 mm) terminals, observing correct polarity. Use a compatible charger or charging system configured for LiFePO4 chemistry and follow recommended charge/discharge currents for best life; typical test values are given at 25°C. When assembling multiple modules, do not exceed four in series or six in parallel. Ensure the intelligent BMS is active and that the system wiring, fuses and any inverter or charger settings match the battery specifications.

Usage recommendations

Store and operate the battery in a cool, dry environment; avoid prolonged exposure above recommended temperatures. For long‑term storage keep the state of charge around 40–60% and check voltage periodically. Follow manufacturer guidance for charging profiles and system integration to maximise cycle life and maintain safety.
