Monitor the battery status (charge, discharge, current, temperature, cycle life and so on) and change the data for different applications.
Push Button Wake-Up/Reset Feature 🔄
Located Conveniently on top of the battery case, this button allows for easy waking up or resetting of the battery, ensuring quick and effortless operation.
Built-in Heating ♨️
Uniform internal heating is an important feature of our cold-weather performance batteries, as many external heating blanket options currently available cannot sense the internal temperature of the cells and may not be completely effective at heating the battery throughout. Our system features proprietary technology that draws power from the charger itself, requiring no additional components. The entire process of heating and charging is completely seamless. Simply plug the battery into our lithium charger and the internal heating and monitoring system takes care of the rest.
More stable and firm internal structure ⚙️
The cell holders within our battery protect and separate each cell to avoid any short circuit risks caused by intense vibration or impact. The separation and space created between each cell also improves the overall heat dissipation within the battery pack while charging and discharging.

T1 – Altitude Simulation
This is low pressure testing that simulates unpressurized airplane space (cargo area) at 15,000 meter altitude. After storing batteries at 11.6kPa for >6 hours, these criteria shall be met: no mass loss, leaking, venting, disassembly, rupture or fire, and voltage within 10% of pre-test voltage.
T2 – Thermal Test
This test covers changes in temperature extremes from -40°C to +75°C. Batteries are stored for 6 hours at -40°C (12 hours for large cells/batteries), then 6 hours at +75°C (12 hours for large cells/batteries), for a total of 10 cycles. Testing may be performed in a single chamber or thermal shock chamber, but less than 30-minute transitions shall be used.
T3 – Vibration
This test simulates vibration during transportation. Test is a Sine Sweep: 7Hz – 200Hz – 7Hz in 15 Minutes; 12 Sweeps (3 hours); 3 mutually perpendicular axes.
T4 – Shock
This test also simulates vibration during transportation. Test is a Half-Sine pulse: 150G/6ms for small cells/batteries; 50G/11ms for large cells/batteries; 3 pulses per direction; 6 directions (+/-z, +/-x, +/-y). Same pass criteria as T1.
T5 – External Short Circuit
This test simulates an external short to the terminals of the cell or battery. At temperature of +55°C, apply short circuit (<0.1ohm) across terminals. Maintain at least an hour after sample temperature returns to +55 +/-2°C. Pass criteria are: Case temperature does not exceed +170°C and no disassembly, rupture, or fire within 6 hours of test. Fuse, current limiting circuit, and venting mechanism activation are allowable.
T6 – Impact
This test is only applicable to primary and secondary cells. For cylindrical cells >20mm diameter, it simulates impact to case of cell. For cylindrical cells <20mm diameter and all other cell constructions, it simulates crushing of a cell. Pass criteria for any type is: Case temperature does not exceed +170°C & no disassembly or fire within 6 hours of test.
T7 – Overcharge
This test is for secondary or rechargeable batteries only. It simulates an overcharge condition on a rechargeable battery: 2x the manufacturer’s recommended charge current for 24 hours. Then battery shall be monitored for 7 days for fire or disassembly.
T8 – Forced Discharge
This testing simulates a forced discharge condition for primary and secondary cells only.
