Humsienk 12V 50Ah LiFePO4 Battery

Yes, this LiFePO4 battery is a drop-in replacement for most 12V lead-acid batteries. It has the same voltage output but is much lighter, more efficient, and longer-lasting. However, ensure your charger is compatible with lithium batteries (with a charging voltage of 14.4V–14.6V). If your system includes a lead-acid charger with desulfation or equalization modes, avoid using it, as it may damage the battery.

The Humsienk 12V 50Ah LiFePO4 battery can last up to 15,000 cycles under ideal conditions, significantly outlasting traditional lead-acid batteries, which typically last 300–500 cycles. This means it can provide power for over 10 years, depending on usage. Unlike lead-acid batteries that degrade quickly with deep discharges, this battery supports 100% Depth of Discharge (DOD) without performance loss.

Yes, this battery is designed for series and parallel connections:
- Series connection (up to 4 batteries) – to increase voltage (24V, 36V, or 48V systems).
- Parallel connection (up to 4 batteries) – to increase capacity (e.g., 12V 200Ah by connecting four 50Ah batteries).
This allows flexibility for larger energy storage setups in solar systems, RVs, and backup power solutions.

To maximize battery life, use a 12V lithium charger with a constant voltage of 14.4V–14.6V. A dedicated LiFePO4 charger ensures proper charging without overvoltage risks. Charging with a lead-acid charger may work, but avoid chargers with desulfation or equalization functions, as they can harm lithium batteries.

Yes, but with some limitations:
Discharging: Works fine in temperatures as low as -20°C (-4°F).
Charging:The built-in low-temperature protection prevents charging below 0°C (32°F) to avoid battery damage. If you need to charge in cold weather, warm the battery above freezing first before charging.

The Humsienk 12V 50Ah LiFePO4 battery has an IP65 rating, meaning it is resistant to dust and water splashes. This makes it suitable for marine use, RVs, and outdoor applications. However, it is not designed for full submersion, so keep the terminals dry and avoid placing it in standing water.

This battery includes a 5-year warranty along with lifetime technical support. If you experience any issues, Humsienk’s support team is available to help troubleshoot and provide assistance.
