6 times super capacitor Adapt to more complete models Comprehensive solution to the central control screen flashing. 30°C Easy at low temperature "Intelligent Heating + Strong Overcurrent" Low Temperature Solution. 4G full network communication Beidou high- positioning Built-in 4G Beidou module, supports long-distance communication and Beidou high- real-time positioning. Dual UART communication interfaces enable expansion of smart accessories. The die-cast aluminum housing is one-piece formed without thermal blocking points, which makes the heat conduction more efficient. Better structural strength and sealing, Effectively dustproof and shockproof, suitable for long-term stable heat dissipation in complex environments. 4G positioning antenna parameters Antenna screw hole size:12.5-13mm Antenna mushroom head diameter:46±1mm Antenna screw length:8.5±1mm Antenna mushroom head thickness:15.5±0.5mm parameters Charge/discharge current:200A Main circuit conduction internal resistance:Less than 20m² (The product printed words depending on the batch, but this does not affect use) Charging voltage:27.6V Turn-on voltage 3.4±0.05V Working current:Less than 30mA Turn-on voltage drop:20mV Sleep current:Less than 10mA Balance current:150±30mA :3600S Color: As Shown Material: plastic Package Contents: 1 x Lithium Battery Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
