GPT 12V High-Capacity LiFePO4 Battery (50Ah to 400Ah)

Standard-capacity 12.8V LiFePO4 batteries for heavy-duty off-grid and mobile applications.

What safety protections does the BMS provide?

The all-in-one BMS covers Over-Voltage Protection (OVP), Low-Voltage Protection (LVP), Over-Current Protection (OCP), Over-Temperature Protection (OTP), Low-Temperature Protection (LTP), and Short Circuit Protection — fully automated with no user intervention needed.

What kind of cycle life can I expect?

3000+ deep cycles at 80% depth of discharge. With proper maintenance, this translates to 10+ years of reliable off-grid service — a clear upgrade over lead-acid which typically needs replacement every 2-3 years.

Is this battery suitable for marine environments?

The casing is IP65 rated and described as “heavy-rain resistant.” Combined with corrosion-resistant copper terminals, it’s well-suited for marine house power — running refrigerators, lighting, and electronics on sailboats or cabin cruisers.

What makes this series different from the Mini series?

This series is built for sustained high-current loads. It ranges from 50Ah to 400Ah with heavy-duty machined copper terminals that provide low-resistance conductivity and can handle the demands of RV appliances, large trolling motors, and whole-cabin solar setups without thermal issues.
