Our take on the HumsiENK 12V 100Ah Lithium LiFePO4 Battery Bluetooth with 20A Charger, Group 24

The HumsiENK is a 12V 100Ah LiFePO4 deep-cycle battery in a Group 24 case, sold with a 20A charger. It uses A+ grade cells rated for over 15,000 deep cycles and a 10-year service life, with an IP67 waterproof case and a 100A smart BMS that cuts off at 300±50A. Low-temperature cutoff protects charging below freezing, and units can be wired in series or parallel up to 48V and about 20.48kWh. It suits RV, marine, off-grid and DIY solar builds where a drop-in lead-acid replacement with built-in safety electronics matters more than peak cranking amps.

About the HumsiENK 12V 100Ah Lithium LiFePO4 Battery Bluetooth with 20A Charger, Group 24

This is a 12V 100Ah lithium iron phosphate (LiFePO4) battery with Bluetooth, sold with a 14.6V 20A charger. It is a Group 24 size with a 1280Wh energy rating. It is built with A+ grade cells and is rated IP67 waterproof and shock resistant.

An integrated 100A Smart BMS protects against overcharge, over-discharge, overcurrent and short circuits. It disconnects automatically when discharge exceeds 300±50A. The battery works from -4°F to 158°F (-20°C to 70°C), and a low-temperature cutoff prevents charging below -4°F.

Up to 4 batteries can be connected in series or parallel, for systems up to 48V and 20.48kWh. It can power RV appliances, marine electronics, trolling motors, off-grid and solar systems, DIY power stations, home backup and garden equipment such as lawn mowers and trimmers.

Questions and answers

Is this a good replacement for a lead-acid Group 24 battery?
Yes, for deep-cycle house loads. The Group 24 case fits many existing trays, and LiFePO4 gives far more usable capacity and cycle life than lead-acid. It is not meant for engine starting.
How much can I run on it at once?
The BMS allows 100A continuous discharge, roughly 1,200W, with a cutoff around 300A for surge protection. Size inverters and loads to stay under that continuous limit.
Can I connect several together?
Yes. Units can be wired in series or parallel up to 48V and about 20.48kWh, so four in series makes a 48V pack. Match age and charge state when combining batteries.
Does it charge in cold weather?
It has low-temperature cutoff, so charging pauses below freezing to protect the cells. Discharging is rated from -4°F to 158°F.
What is in the box?
The 12V 100Ah LiFePO4 battery and a 20A charger. Bluetooth monitoring is built into the battery.
Do I need a special charger?
Use a LiFePO4-compatible charger set to the battery's absorption voltage; the included 20A charger is matched to it. Avoid lead-acid chargers with desulfation modes.
