  • [10-Year Longevity] HQST's 12V lithium batteries come with a reassuring 10-year commitment to both product quality and service life. This marks a significant advancement over lead-acid batteries, which usually last only 1 to 3 years. A perfect option to replace lead-acid batteries and enjoy extended durability.
  • [Low & High Temperature Protection] Equipped with low and high temperature cut-off protection, HQST LiFePO4 battery ensures safety during charging and discharging processes. When temperatures dip below 23℉ or rise above 140℉, the battery's charging is auto suspended to preserve its lifespan. Similarly, if temperatures fall below 5℉ or exceed 158℉, discharging will cease, maintaining optimal performance.
  • [In Series & Parallel] Connections HQST's 12V 100Ah lithium battery supports series and parallel connections. You can create a 12V, 24V, 36V, or 48V battery bank via series wiring, a 12V 200Ah, 300Ah, or 400Ah power system via parallel connections, or even connect up to 16 batteries in series and parallel, building a powerful home backup power system with a 20.48 kWh capacity.
  • [100% Power Output] The HQST 12V 100Ah LiFePO4 battery delivers an impressive power output of 1,280 Wh, 2 to 3 times more potent than conventional sealed lead-acid batteries. With a continuous discharge current of up to 100A, it can power most household appliances.
  • [Durable and Lightweight] Weighing only 25.11 lbs, this 12V LiFePO4 battery is smaller, lighter, and at the same time delivers more power than conventional lead-acid batteries. The improved BMS expertly manages cell balance, over-current, over-charge, over-discharge, temperature extremes, and short circuits, providing enhanced performance and prolonged lifespan.

How many life cycles does this LiFePO4 battery have?

This HQST Deep Cycle LiFePO4 Battery enables more than 3,000 charge/discharge cycles at 80% DOD (Depth of Discharge), and more than 4,000 cycles at 70% DOD.

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.

Does this battery have low temp and high temp protection?

Yes, this battery has low temperature protection and high temperature protection. When the temp is below 23℉ or over 140℉, the battery will stop being charged to protect its lifespan. When the temp is below 5℉ or over 158℉, it will stop discharging.

Can I run these batteries in series and in parallel?

Yes. These HQST lithium batteries support series and parallel connection. Please note that you need to use identical batteries to connect.
For optimal performance, we kindly advise you to follow the requirements listed below to connect your batteries together:
1. Fully charge all ready-to-connect batteries.
2. All battery interconnect cables should be the same wire gauge (AWG) and length, and come from the same brand. Otherwise, the impedance will be inconsistent, resulting in unbalanced charge and discharge performance.
3. Connect your batteries one by one in series (up to 4 batteries) or in parallel (up to 4 batteries). Secure all cable connections between the cable lugs and terminals.

Does this battery have low voltage protection?

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

How to properly store this battery?

To store your battery, keep it at least 30%-50% charged. We recommend that you charge the battery every 6 months when not in use to prevent overdischarge. When storing the battery for 1-3 months, you can place it in an environment with a temperature range of -4℉~113℉/-20℃~45℃; when storing it for 1 year, it is recommended to place it in an environment with a temperature range of -4℉~68℉/-20℃~20℃.
