Stay Cool Without Idling Your Truck
Before: The Cost of Staying Cool
Idling burns fuel. Summer heat makes rest harder. As regulations change, fuel prices rise, and summer temperatures climb, traditional idling becomes an expensive way to stay comfortable. With 1,800 hours of annual idling, $4.21 per gallon diesel, and overnight AC use, drivers can spend about $7,500 per year on fuel.
After: A Smarter Way To Stay Cool
A LiTime 320Ah truck LiFePO₄ battery solution can reduce annual operating costs and help drivers save around $6,000 per year by reducing engine idling, fuel consumption, and unnecessary expenses. LiTime keeps your AC running while helping you save fuel, reduce costs, and create a more comfortable rest experience every night.

Main installation spot: Under bunk bed for daily appliances, mainly powering air conditioner; secondary option: truck APU box if power input is available; rarely fitted in cab startup area.
How long can a 12V 320Ah LiFePO₄ truck battery power Truck common appliances?
A fully charged 12V 320Ah (4096Wh) LiFePO₄ truck battery can power a variety of appliances. Under ideal conditions, it can run an 800W air conditioner for up to 5.1 hours, a 700W microwave for up to 5.9 hours, or a 45W refrigerator for up to 91 hours. Actual runtime may vary depending on inverter efficiency, battery condition, and the appliance's power consumption. In general, appliances may run longer in spring and fall than in summer due to lower energy demand.
Can I run my Truck AC while the engine is completely off?
Yes. A lithium battery system can power your parking AC overnight without starting or idling the engine, as long as the battery capacity is sufficient for your AC power needs.
Can I use this LiTime 12V 320Ah truck Lithium batteries as starting batteries?
No. This battery is not intended to be used as starting batteries but energy storage, please do not use them to start any devices. Do not mount them in the front starter battery compartment or use them to crank the engine, otherwise the BMS will get damaged.
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 if SOC>20% .
What makes the 12V 320Ah truck battery different from a regular 12V 300Ah battery?
This LiTime 12V 320Ah Mini with Self-Heating delivers more energy with less bulk. It's 35% smaller than typical 12V 300Ah LiFePO₄ batteries and 70% lighter than three 100Ah lead-acid units—while offering a high-energy 4096Wh output and up to 200A continuous discharge. That means you get max energy density, easier installation, and better portability—all in one compact unit.
Can I charge 12V 320Ah Lithium truck batteries under freezing temperatures?
Yes. The 320Ah self heating truck lithium battery can safely charge between -20℃ ( -4℉ ). The 2 self-heating modes will start heating the battery before charging.
