High CCA Lithium Starter Battery 12.8V 24.2Ah 3.5kg IP56 ABS Case M8

High CCA Lithium Starter Battery 12.8V 24.2Ah 3.5kg IP56 ABS Case M8

Powerful Starting Battery for Trucks
This 12.8V 24.2Ah lithium iron phosphate battery is engineered for starting diesel and petrol truck engines. With a cold cranking ampere rating of 1000 CCA, it delivers reliable starting power even in cold weather. Weighing only 3.5kg, it is a fraction of the weight of a lead acid battery with similar CCA. The integrated BMS protects against overcharge, over discharge, overcurrent, short circuit, and temperature extremes. The IP56 rated ABS housing resists dust and powerful water jets, making it suitable for engine compartment installation.

Core Specifications
Nominal voltage is 12.8V with 24.2Ah rated capacity. Total energy is 309.8Wh. Internal resistance is extremely low at ≤2.5 milliohms. Efficiency reaches 99 percent. Self discharge is only 2 percent per month. Cycle life exceeds 3000 cycles at 1C and 80% depth of discharge while retaining over 80% capacity. Cell configuration is 4 series and 11 parallel (4S11P). Dimensions are 165mm length, 126mm width, and 175mm height. Weight is 3.5 kilograms. Terminal type is M8. Housing is ABS with IP56 protection. Cell chemistry is LiFePO4.

Discharge Performance
Continuous discharge current is 24.2 amps. Cold cranking ampere rating is 1000 CCA, providing ample power to start large displacement diesel engines. Recommended voltage disconnect is 10V. BMS discharge cut off voltage is 14.5V (note: likely a typo in datasheet; typical cut off should be around 10V for a 12.8V battery). Reconnect voltage is 10.8V. Short circuit protection activates within 300 to 800 microseconds.

Charge Parameters
Charging uses the CC CV method with charge voltage of 14.4V. Recommended float voltage is 13.4V. Standard charge current is 24.2 amps (1C). Maximum charge current is 96.8 amps (4C) for fast charging. BMS charge cut off voltage is set to 14.4V.

Cycle Life and Longevity
Rated for over 3000 cycles at 1C charge/discharge and 80% depth of discharge. For a truck that starts twice daily, this provides over 4 years of reliable service. The low self discharge means the battery stays ready after long periods of inactivity.

Temperature Range
Discharge temperature range is -20°C to 60°C. Charge temperature range is 0°C to 45°C. Storage temperature range is -20°C to 45°C. BMS high temperature cut off is set to 78°C, providing an extra safety margin under hood.

Extremely Low Internal Resistance
The ≤2.5mΩ internal resistance ensures minimal voltage drop during high current cranking. This allows the battery to deliver maximum power to the starter motor, resulting in faster engine starts even in cold conditions.
