[💥Clearance Sale] Humsienk 12V 8Ah LiFePO4 Battery

The Humsienk 12V 8Ah LiFePO4 battery is perfect for small-scale applications such as:
1. Solar-powered systems (small lights, security cameras, and garden setups)
2. Portable electronics (fish finders, small fans, and LED lighting)
3. Backup power supplies for routers, medical devices, and emergency kits
4. Outdoor and camping gear like electric fences and portable speakers

Compared to traditional lead-acid batteries, this LiFePO4 battery:
✅ Lasts 5-10 times longer (up to 15,000 cycles)
✅ Weighs 70% less, making it easy to carry
✅ Maintains consistent power output without voltage drops
✅ Charges faster and is more energy-efficient

Some UPS systems support LiFePO4 batteries, but many are designed for lead-acid chemistry. Check if your UPS allows a charging voltage of 14.2V-14.6V before replacing the battery.

Yes! You can:
Connect in series (4S) up to 48V for higher voltage applications.
Connect in parallel (4P) up to 32Ah for increased capacity.
Make sure all batteries are at similar voltage levels before connecting them.

Absolutely! Unlike lead-acid batteries, LiFePO4 batteries do not produce harmful gases and are completely sealed. They are safe for indoor and enclosed spaces, including homes, offices, and RVs.

This battery operates in temperatures from -4°F to 140°F (-20°C to 60°C). However, charging below 32°F (0°C) may reduce efficiency. If using in extremely cold conditions, keep the battery insulated or opt for a model with low-temperature charging protection.

For best performance, use a LiFePO4-compatible charger with an output of 14.2V-14.6V. A 1A-2A charger is ideal for this 8Ah battery. Avoid standard lead-acid chargers unless they support lithium batteries.

If the battery seems unresponsive, it may have entered BMS protection mode due to:
1. Over-discharge
2. A short circuit
3. Excessive current draw

To reset it:
Connect it to a LiFePO4 charger and let it charge for 5-10 minutes.
Check that the battery terminals are secure and free of corrosion.
If the issue persists, contact Humsienk support—we provide a 5-year warranty and lifetime technical assistance.
