In the pursuit of free energy, Humsienk was born from a simple but powerful idea: to create a more efficient, lighter and longer-lasting power solution. Traditional lead-acid batteries are difficult to meet the needs of modern outdoor, RV, marine and energy storage users due to their heavy weight, short life and slow charging. We decided to challenge the limits and use innovative technology to bring truly durable and high-performance lithium batteries.
Break through limitations and create a more powerful source of power
Humsienk 12V 150Ah LiFePO4 battery is not just a battery, but an upgraded alternative to 12V 100Ah, 12V 50Ah and traditional lead-acid batteries. It provides longer battery life, higher output, and a lighter design, while optimizing the price, allowing users to truly balance performance and cost performance.
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.
