Advantages

  • High-power cranking capability: Easily drives large-displacement agricultural engines; reliable cold start at low temperatures.

  • Safe & durable sodium-ion cells: Excellent thermal stability; safe against vibration and outdoor storage.

  • Ample energy reserve: Supports long-hour farm operations and reduces intermediate recharging.

  • Long cycle life: Sodium-ion cells withstand frequent start-stop cycles for farm machinery.

  • Application-specific design: Optimized for farm working conditions, balancing cranking power and runtime for outdoor field emergency & continuous use.

  • Wide temperature range: Operates at -10°C~80°C, performs reliably under frigid mornings/evenings and hot sun exposure

Advantages

  • Ultra-low temperature resistance: Reliable starting for diesel equipment at -40°C extreme cold.

  • Ultra-fast charging: Full charge in 20 minutes, greatly reducing waiting time.

  • Extra-long service life: Cycle life 5-8 times longer than traditional lead-acid batteries for high durability.

  • Lightweight & compact: 1/2 the volume and 1/3 the weight of lead-acid batteries, saving installation space and equipment load.

  • High-rate discharge: Strong instant power output for smooth heavy-load diesel engine start-up.

  • Maintenance-free design: No regular water topping-up or electrolyte testing; ideal for long-term outdoor diesel-equipment operation.
