Humsienk 12V 150Ah Group 31 Bluetooth LiFePO4 Battery 1.92kWh for RV & Boat

This battery has a rated capacity of 150Ah (amp-hours) and an energy rating of 1920Wh (watt-hours).

💡 Testing Method: Using a constant current discharge of 0.2C (30A) down to a 10V cutoff voltage, it delivers approximately 150Ah.

⚠ Beware: Some brands may overstate capacity. Humsienk guarantees full, accurate capacity with no overstatement.

Continuous discharge current: 110A (suitable for most applications)

Peak discharge current: 300A (≤5 sec)

Minimum cutoff voltage: 10.0V

💡 For high-power devices like inverters or motors, ensure the power demand does not exceed 300A peak discharge.

Not recommended!

✔ Recommended Charging Methods:

LiFePO4 Charger (14.6V 20A-50A) → Best option for performance and safety

Solar Charging (MPPT Solar Controller required) → Suitable for off-grid setups

Vehicle Charging (DC-DC Converter required) → Ideal for RVs and boats

⚠ If using a lead-acid charger, ensure:

Charging voltage ≤ 14.6V (to prevent overcharging)

Equalization mode is turned OFF (as it may damage LiFePO4 cells)

💡 For best performance and lifespan, use a 14.6V 50A LiFePO4 charger.

✔ Discharge temperature range: -4°F to 140°F (-20°C to 60°C)

✔ Charging temperature range: 32°F to 113°F (0°C to 45°C)

✔ Low-temperature charging cutoff to prevent damage below 32°F (0°C).

⚠ If charging in extreme cold (below 0°C), use a heated battery or insulate the battery properly.

💡 The battery can still discharge in cold weather but cannot charge below freezing!

✔ Supports parallel connection (increase capacity) → Up to 4P (12V 600Ah max)

✔ Supports series connection (increase voltage) → Up to 4S (48V max)

Connection Guidelines:

Use batteries of the same brand, model, and batch, with voltage differences ≤ 0.1V.

Charge each battery fully before connecting for balance.

Do not exceed 4S4P configuration, as it may affect the BMS protection.

💡 For larger systems, seek professional advice before connecting.

✔ 15,000+ charge cycles (at 80% Depth of Discharge, DOD)

✔ 6,000+ cycles (at 100% DOD, full discharge)

✔ 10-15 years of service life, significantly outperforming lead-acid batteries (300-500 cycles).

💡 Shallower discharges extend lifespan—aim for 80% DOD for longevity.

✔ 110A BMS with:

Overcharge protection (>14.6V cutoff)

Over-discharge protection (<10.0V cutoff)

Short circuit protection (instant shutdown on short circuit)

Temperature protection (cuts off charging if too hot or too cold)

Cell balancing (ensures equal voltage among cells for longer lifespan)

💡 BMS safeguards the battery against improper use, ensuring safety and longevity.

✔ Can discharge down to 10.0V, but frequent deep discharges shorten lifespan.

✔ Recommended discharge range: 20%-100% for optimal longevity.

💡 Avoid draining to 0% often, as it accelerates battery degradation.

✔ IP65-rated waterproof and dustproof—resistant to dust and low-pressure water jets.

⚠ Not submersible or suited for extreme humidity exposure.

💡 Perfect for outdoor use, but avoid prolonged exposure to extreme weather conditions.

✔ 5-year warranty (longer than industry standard)

✔ 30-day hassle-free return & exchange policy

✔ Lifetime technical support

💡 Humsienk provides full support for worry-free usage.
