True Technology · Hard Power
Two Leading Technologies, Showcasing Hard Power
01.National Patent Potting Technology
Waterproof & Dustproof
Fully sealed "integrated molding potting" technology effectively prevents
water and dust, delays aging, and greatly extends BMS lifespan.
Shock Absorption & Vibration Resistance
High molecular polymer fills the inside of the BMS, completely wrapping components,
fully absorbing shocks and other impacts, effectively protecting the BMS.
Components Encapsulated by Potting Impact-resistant Aluminum Alloy Case Secured with Multiple Screws
02. 10x Super Heat Dissipation Technology Aluminum Alloy Material 4x Faster Heat Dissipation Thermal conductivity of aluminum alloy is as high as 237 W/(m·K) Thermal conductivity of iron is as high as 60 W/(m·K) *Based on experimental data under standard atmospheric pressure, room temperature, and solid-state materials. *Red components in the right image are aluminum alloy. |
|
| Wavy Design 2.5x Larger Heat Dissipation Area The cooling panel uses a non-traditional wavy design, increasing the heat dissipation area by more than 2.5 times compared to a flat panel. |
Active Fan Cooling Higher Heat Dissipation Efficiency High-power cooling fan delivers air up to 100mm/min, removing heat faster and more efficiently. |

Step 1: Connect the 1st wire (black) of the harness to the battery main negative; connect the 2nd wire (red) to the positive of the 1st cell, the 3rd wire to the positive of the 2nd cell... and so on, connect all wires.
Step 2: After connecting the harness, measure the voltage between every two adjacent wires starting from the connector end.
Step 3: Secure the BMS. Measure and confirm the voltage between B- and P- on the BMS is correct, then insert the harness connector into the BMS.
Step 4: Connect the BMS B- wire (blue) to the battery main negative. Connect the BMS P- wire to the negative terminal of the charge/discharge port. Connect the battery main positive to the positive terminal of the charge/discharge port.
Step 5: Measure the total battery voltage and the output voltage of the BMS. It is normal if the voltages are equal.
