Built tough, this HQST 12V 100Ah lithium battery packs more power for your next adventure. The optimized BMS combines low and high temp protection to provide improved charging and discharging safety. Supports connecting up to 4 in parallel and 4 in series to wire 16 batteries to build a powerful home battery bank system with a power of 20.48 kWh. 

With a lifespan of 4,000 cycles (70% DOD), this battery will last up to 8 times longer than your conventional sealed lead-acid battery - providing exceptional value over time. Perfect for family RVs, off-grid cabins, marine vehicles, solar energy, and more.

Important Note:

● Make sure to tightly screw the battery terminals in, as having loose battery terminals will cause the terminals to build up heat resulting in damage to the battery.

●  When the battery is fully discharged at a continuous 100A, it cannot be recharged at 50A immediately, which will trigger high temperature charging protection.

Warranty Information

  • 10-year material warranty

1.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.

2. 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.
3. 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.

4. 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.

The DC voltage rating on the inverter will tell you what battery bank it is compatible with. For example, a 12V battery bank will require an inverter that is compatible with 12V DC input.

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.

5. 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. "

6. 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℃.
