CARKU JS-617N: 12V/24V Jump Starter for Passenger and Commercial Vehicles

CARKU JS-617N combines intelligent voltage recognition, manual-start capability, and multi-layer safety protection for reliable vehicle starting in demanding conditions:

• Extreme-Temperature Performance: The JS-617N has successfully started vehicles at temperatures as low as -40°C^[2], demonstrating its capability in extreme cold.
• Automatic Voltage Recognition: Automatically recognizes the vehicle voltage when residual battery power is available, while one-click manual startup provides an alternative when the vehicle battery is too depleted for automatic recognition.
• 10 Safety Protection Functions: Integrates 10 protection functions covering electrical, thermal, and software safeguards to help ensure safe and reliable operation.

CARKU-G51-24V: Sodium-ion Starting Battery for Commercial Vehicles

Beyond LiFePO4, CARKU is extending its starting battery technology with Na+ chemistry. Leading the lineup is the CBN50-G51-24V, a sodium-ion starting battery developed for commercial vehicles operating in demanding temperature conditions. Its Na+ chemistry is designed to support reliable engine starting across a wide temperature range.

CARKU CBL230D-24V: LiFePO4 Dual-Purpose Battery for Commercial Vehicles

CARKU also showcased the CBL230D-24V, a LiFePO4 battery designed to combine engine starting with auxiliary power for fuel-powered trucks. When paired with a power inverter and parking AC system, it can support an integrated power solution for commercial vehicles. This 24V battery series is already in mass production in Southeast Asia, reflecting CARKU's broader push to extend LiFePO4 applications across automotive, marine, and truck sectors as an alternative to traditional lead-acid batteries.
