LiTime LiHeat® 12V 165Ah Dual-Mode Self Heating Lithium Battery

Q: How does the new self-heating function work?

When manually choose “Energy-Efficient” mode to initiate preheating through LiTime app, it enables the battery to utilize its own stored energy for self-heating.

Q: What are the differences between 2 Self-Heating Mode?

Regular Mode: Heats the battery via an external charger.Energy-Efficient Mode: Self-heats using its own power, shortens warm-up time.

Q: Can I add heating facilities to help with external heating?

External heating only heats the casing and does not heat the battery cells. In conditions of -20°C, after external heating for two hours, the battery cells temperature rise to 5°C, but the lead-acid casing temperature has risen to 70-80°C.Therefore, it is not recommended to externally heat the battery, as the actual cell temperature cannot be determined at this time.

Q: Do I need a 12V 165Ah self-heating lithium battery?

We've had customers use this battery when skiing ice fishing or doing other various winter activities. You can use and discharge LiTime lithium batteries in cold temperatures, but a self-heated battery might be what you want if you plan to charge it in the cold.

Q: Can I charge 12V 165Ah self heating batteries in cold weather (under freezing temperatures)?

Yes. The 165Ah self heating lithium battery can safely charge between -20℃ to 50℃ ( -4℉ to 122℉). The 2 self-heating modes will start heating the battery before charging.Recommended reading on LiFePO4 Temperature Range Guide for more information on safe usage and performance.

Q: Can Bluetooth and non-Bluetooth batteries be connected in series or parallel?

It is strongly not recommended. Only Bluetooth-enabled batteries can be monitored individually, while the system as a whole cannot be tracked. Mixing them may compromise total capacity and system performance.

Q: Is the BMS passive or active balancing?

The 12V 165Ah li-ion battery uses passive balancing technology, which safely manages cell voltage differences to maintain battery longevity and stability.

Best RV Batteries!

We have a Patriot Camper that came with 300AH AGM ridiculously heavy batteries, replaced with two of these and more than doubled our capacity AND dumped a ton of weight! Also, self heating so no issues in cold weather!
Couldn’t be happier.
