Humsienk 12V 100Ah Group 24 Lead-acid Replacement Bluetooth LiFePO4 Battery 1.28kWh for RVs/Boats

Yes! Our LiFePO4 batteries are designed for series and parallel connections to expand voltage or capacity:

Series Connection: Up to 4 batteries can be connected in series to achieve 24V, 36V, or 48V systems for higher voltage applications like golf carts and solar storage.

Parallel Connection: You can connect up to 4 batteries in parallel to increase the capacity to 400Ah for extended power storage (up to 20.48kWh total).

⚠️ Important: Always use identical batteries (same model and capacity) for safe and optimal performance.

Yes! Our Bluetooth-enabled version allows real-time monitoring via a dedicated mobile app (compatible with Android 4.3+ and iOS devices). The app provides detailed battery status, including:
✔ Battery voltage and state of charge (SOC)
✔ Charging and discharging current
✔ Temperature monitoring
✔ Cycle life tracking
✔ Protection status and alerts
📌 Tip: Bluetooth function works within a 5-10m (16-33ft) range. Ensure GPS permissions are enabled for connectivity.

For optimal charging and battery life, we strongly recommend using a 14.6V LiFePO4 charger with an output of 20A. Using an incorrect charger (such as a lead-acid charger with automatic desulfation) can damage the battery.
✔ Standard Charging: 14.6V, 20A for full charge in ~5-6 hours
✔ Fast Charging: Up to 50A (if your setup requires faster charging)
✔ Trickle Charging: 10A or lower for maintenance charging

Yes! Our low-temperature protection feature ensures safe operation in extreme weather conditions.

Operating Temperature: -4°F to 158°F (-20°C to 70°C)

Charging Temperature: 32°F to 122°F (0°C to 50°C)
📌 Tip: In freezing temperatures (below 32°F/0°C), the built-in BMS prevents charging to protect the battery. To charge in cold climates, consider a self-heating version or preheat the battery before charging.

Yes! It features an IP65 waterproof rating, which means it is dustproof and resistant to water splashes.
✔ Suitable for outdoor use, RVs, boats, and off-grid setups
✔ Resistant to moisture and light rain exposure
⚠️ Not submersible – Do not expose it to direct water submersion.

This battery is designed for 15,000+ deep cycles at 80% Depth of Discharge (DOD), meaning it can last 10+ years with proper care. In comparison, traditional lead-acid batteries only last 300-500 cycles.
✔ Lead-Acid Lifespan: ~2-3 years
✔ Humsienk LiFePO4 Lifespan:10+ years
📌 Tip: Avoid overcharging or discharging below 10% to maximize lifespan.

Absolutely! The built-in 100A Smart BMS (Battery Management System) provides:
✔ Overcharge & Over-discharge Protection – Prevents battery damage
✔ Short-Circuit Protection – Ensures safety in case of electrical faults
✔ Temperature Protection – Prevents overheating and freezing-related issues
✔ Current Overload Protection – Automatically disconnects in case of excessive current draw (300A±50A cutoff)
📌 Tip: If the BMS disconnects the battery for safety reasons, simply wait a few minutes and reconnect.
