Yes! The Humsienk 12V 100Ah LiFePO4 battery supports:
– Create a 48V system for solar storage, RVs, and marine use.
– Expand capacity up to 20.48kWh for larger energy storage needs.
📌 Note: When connecting in series or parallel, all batteries should have the same voltage, capacity, and manufacturing date to ensure optimal performance and safety.

Yes! It is a drop-in replacement for 12V lead-acid batteries, offering higher efficiency, longer lifespan, and lighter weight.
-Lead-acid batteries typically last300-500 cycles, while this LiFePO4 battery lasts 15,000+ cycles, offering 10 times the lifespan.
-Lead-acid batteries have a 50% depth of discharge (DOD), while LiFePO4 batteries can be discharged 100%, giving you more usable power.
-Faster charging, no maintenance required, no need to add water, and no memory effect!

Yes, this battery is designed for extreme conditions and has built-in low-temperature protection.
Discharge Temperature Range: -4℉ ~ 158℉ (-20℃ ~ 70℃)
Charging Temperature Range: 32℉ ~ 131℉ (0℃ ~ 55℃)
Low-Temperature Charging Protection: The BMS will automatically stop charging below 32℉ (0℃) to prevent battery damage.

📌 Tip: For charging in extremely cold environments, consider batteries with a built-in heating function or use a battery heating pad.

It is recommended to use a LiFePO4-specific charger or a smart charger with a LiFePO4 charging mode.
📌 Recommended Charging Parameters:
- Charging Voltage: 14.4V - 14.6V
- Cut-off charging Current: ≤0.05C (below 5A)
- Maximum Continuous Charging Current: 50A

❌ Do not use traditional lead-acid battery chargers with desulfation (high-voltage pulse) modes, as they may damage the BMS system.
