24V 200Ah Parking Air-Conditioner Battery for Trucks is a LiFePO4 parking and start battery for trucks, buses and heavy vehicles. This 24V 200Ah battery is sized to run an overnight parking air-conditioner and still retain enough capacity for the next day's start. It provides 5.12 kWh of nominal energy at 25.6V (24V class) and weighs approximately 28 kg, replacing lead-acid units of the same group size.
Cell & BMS Technology
The battery uses grade-A prismatic LiFePO4 cells in a 8S1P configuration with a dedicated 8S, 100A BMS. Protection covers over-charge, over-discharge, over-current, short-circuit and over-temperature events, plus low-temperature charge cut-off to prevent lithium plating in cold weather. Communication is available over RS485 / UART, Bluetooth optional, and the BMS retains fault and cycle history for fleet maintenance records.
Safety & Cycle Life
LiFePO4 chemistry gives more than 6,000 cycles at 80% depth of discharge, several times the service life of lead-acid, with no gassing, no acid handling and no stratification from partial charging. The battery operates between -20C and +60C and is sealed to IP65, so it is unaffected by road spray, dust and vibration.
Charging & Alternator Compatibility
Charging is handled by the vehicle alternator or a mains charger at a recommended voltage of 28.8V and up to 100A. With a 100A continuous charge rating the battery recharges from the alternator during daytime driving without additional equipment in most installations. An optional DC-DC charger or isolation relay is available where the vehicle alternator output must be regulated for lithium charging.
Mechanical & Enclosure
The enclosure is sealed ABS shell with steel mounting frame with dimensions of 480 x 260 x 220 mm. The case uses a standard truck battery tray footprint with a steel mounting frame and hold-down points. Terminals are M8 bolt terminals, matching common OEM and retrofit cable lugs.
Typical Use Cases
Fitted to long-haul trucks, sleeper cabs and refrigerated units where drivers run air-conditioning overnight at rest stops, reducing idling time, fuel consumption and engine wear.
Customisation
Capacity, case size, terminal layout, BMS current rating, heating function, communication protocol and brand labelling can be customised for fleet and distributor programmes. Heated versions with internal heating film are available for cold-climate routes, and parallel connection kits allow two batteries to be combined for larger parking air-conditioner loads.
Every battery is capacity-tested, high-current-tested and balance-tested before shipment. Compliance target standards: UN38.3, IEC 62619, CE and RoHS. Warranty: 3 years / 5 years optional.
