## Summary description

NPP LFP12.8-18 is a rechargeable LiFePO4 (lithium iron phosphate) battery with nominal 12.8V voltage and 18Ah capacity. Designed for use in UPS, solar energy systems, RVs, portable power packs and other backup applications. Offers stable output, long cycle life and safer chemistry compared with lead‑acid batteries, reducing maintenance and weight for mobile and stationary setups.

## Long description

NPP LFP12.8-18 is a rechargeable LiFePO4 (lithium iron phosphate) battery with a nominal voltage of 12.8 V and a capacity of 18 Ah. It is designed for UPS systems, solar energy installations, portable power packs and other backup and mobile applications where stable output, long cycle life and reduced weight are important. The battery uses lithium‑iron phosphate chemistry and an intelligent battery management system to provide reliable performance and enhanced safety compared with conventional lead‑acid batteries.
Advantages
The NPP LiFePO4 battery delivers up to 100% usable energy and charges faster than sealed lead‑acid batteries. It is about 60% lighter than equivalent lead‑acid units and demonstrates low self‑discharge (≤3% per month at 25°C). The cell chemistry and integrated BMS allow high discharge rates and a long service life — over 3,000 cycles at 100% depth of discharge — as well as improved float/calendar life.
Suitable for
Uninterruptible Power Supplies (UPS)
Solar and wind energy storage systems
Portable power stations and camping power
RVs and marine applications, including powering fish finders
Telecommunication and data center backup
When it may not be suitable
This battery may not be suitable for applications that require voltages or capacities other than 12.8 V / 18 Ah without additional system design (e.g., many modules in series or parallel). Also, devices that strictly require lead‑acid specific charging profiles without a compatible charger may need an appropriate LiFePO4‑capable charger or charge controller.
Key specifications
Nominal voltage: 12.8 V
Rated capacity (5 h, 25°C): 18 Ah
Energy: 230 Wh
Charge efficiency (0.2C, 25°C): 99.5%
Cycle life: \>3,000 cycles at 100% depth of discharge
Self‑discharge: ≤3% per month at 25°C
Maximum modules: up to 4 in series per string, up to 6 in parallel
Terminal type: T2 / F2 (6.3 mm)
Dimensions (L×W×H): 151±2 × 99±2 × 94±2 mm (total height 94±2 mm)
How to use
Install the battery in a dry, ventilated location and connect using the T2 / F2 (6.3 mm) terminals. Use a charger or solar charge controller configured for LiFePO4 chemistry and observe recommended charge/discharge currents to maintain long life. For higher voltage or capacity, connect modules according to the allowed configuration limits (maximum 4 in series per string and up to 6 in parallel) and ensure the system’s BMS or external management supports the combined setup.
What to consider before purchase
Verify that your charger or inverter supports LiFePO4 charge profiles
Confirm required voltage and capacity and whether series/parallel expansion is needed
Check physical dimensions and terminal type (T2 / F2) for compatibility with your enclosure
Usage recommendations
For best results, use a LiFePO4‑compatible charger or MPPT solar charge controller, avoid deep discharge beyond recommended limits when possible, and allow proper ventilation. When paralleling or stringing batteries, ensure balanced wiring and compatible BMS settings to maintain performance and safety.
