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.

Runtime mainly depends on the battery voltage, capacity, and the power consumption of the appliances. For example, a fully charged 12V 320Ah (4096Wh) LiFePO₄ 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.

Yes. A lithium semi truck 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.

It reduces engine idling time, helping lower fuel consumption and operating costs about $6000 during hot summer nights.

A high-capacity LiFePO4 battery, DC-DC charger, and parking AC system are recommended for a reliable sleeper cab power setup.

It depends on the A/C type.12V DC A/C runs directly from a 12V LiFePO4 battery, with a DC-DC charger recharging it while driving. AC A/C requires an inverter, typically 2000W–3000W depending on power needs.

It helps power onboard loads without running the engine, reducing fuel use, noise, exhaust, and operating costs during parked rest.

No. This battery is not intended to be used asstarting batteriesbut 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.
