  • Real-time LED display shows state of charge, voltage, and charge/discharge current at a glance.
  • Charging stops automatically below 32°F (0°C) and resumes above 41°F (5°C); discharge cuts off below –4°F (–20°C) to prevent cold-weather damage.
  • Delivers 1280Wh usable capacity and 100A continuous current — 2–3× more powerful than equivalent lead-acid batteries.
  • Weighs just 22 lbs, roughly 1/5 the weight of a 12V 200Ah lead-acid battery, yet fits the standard Group 31 size (13.07" × 6.77" × 8.66") for drop-in replacement.
  • Features <3% monthly self-discharge at 77°F (vs. up to 30% for lead-acid), built with Grade A+ UL-tested cells for a 10-year lifespan and backed by a 10-year warranty.
  • Easily scalable up to 4S4P, supporting systems up to 20.48kWh.
  • Advanced BMS provides 20+ protections against over/under-voltage, over-current, short circuits, and extreme temperatures.
  • IP65-rated for dustproof and water-resistant outdoor reliability.
  • Ideal for RVs, trailers, trolling motors, boats, off-grid cabins, and home backup during winter storms or hurricane season.
  • Not for engine starting — for deep-cycle use only.

Why Isn’t the LED Display Accurate?

If the LED display isn’t showing the correct readings, you can try calibrating it by following these steps:
1. Discharge the battery completely to 0%.
2. Use a compatible LiFePO4 battery charger or solar charge controller to fully charge the battery.
If the issue persists, please contact us at sales@myhqsolar.com for further assistance.

What are the charging voltage and charging current for this battery?

The max. charging voltage is 14.6V and the max. charging current is 50A. For optimal charging performance, we highly recommend adjusting the voltage to 14.2V-14.6V and using a 20A charger.

Does this 12V 100Ah battery offer low-temperature protection?

Yes, it does. When the temp reaches -5℃~5℃, this lithium battery will stop being charged, and when the temp reaches -25℃~15℃, the battery will stop discharging. Ideal for harsh and rugged environments. It also has high temperature protection.

Does this battery have low voltage cut-off protection?

Yes, it does. When the discharge voltage is lower than 11.1V, the battery will shut off automatically.

Can I use my lead acid battery charger to charge the lithium battery?

We recommend using a lithium battery compatible AC to DC charger to charge LiFePO4 batteries, or else cause unreversible lifespan damage to the batteries. You can also charge these batteries using compatible solar charge controllers and solar panels.

Will the battery come with the terminals? And if not, what's the size of the connector terminals?

Yes, it comes with two M8 screw terminals.

Can I charge the battery directly using a solar panel?

No, you should not connect the solar panel directly to the battery. When charging this battery with a solar panel, make sure to use a solar charge controller (either PWM or MPPT) between the panel and the battery. Directly connecting the panel to the battery could result in unstable solar power, which may damage your devices.
