E-bike battery level indicator light. Press the switch to display the current battery level, when the power indicator only shows the red LED, it is necessary to charge the battery.
The power switch controls the operating status of the lithium battery. When the switch is closed the battery will enter a low loss state and the battery will no longer supply power to the motor. The battery will be activated when the switch is turned on.
Lithium-ion battery USB port can provide charging for mobile devices. It can be customized with 5-12V output voltage and 1-2A current. The USB port is female.
A Bluetooth-enabled BMS can be installed inside the battery, and the battery condition can be checked at any time by connecting to the battery using Bluetooth on your cell phone. It is also possible to turn off the battery and adjust the battery parameters remotely by Bluetooth.
Battery charging and discharging insurance. Additional fuse is added to the positive side of the battery discharge line. Effectively prevents damage to the battery BMS caused by motor controller, external short circuit, etc. The charging insurance prevents battery damage caused by charger damage or lightning.
ebike lithium battery waterproof rating is IP650. ebike battery internal battery pack wrapped with insulating waterproof PVC, can effectively prevent the infiltration of rain. There is a danger of short circuit in heavy rain. You can additionally increase the battery waterproof production process for all seams of the battery.

The current Down tube type battery style can be installed in the maximum 40A BMS, the maximum continuous current of 50A. The common 350-500W motor is 20A current, 750-1000W motor is 30A current. The higher the current, the stronger the power, but also very fast power consumption.
We have Korean Samsung, LG and Japanese Panasonic, Sony 18650 Li-ion cells. China’s BAK,DLG,EVE,MOLI 18650 Li-ion cells. At present, the hot market is Samsung 35E, 30Q, 29E and other models of cells. We can also help you to source other cell brands you specify.
Battery cells are mainly distinguished by capacity, material, brand, discharge rate. ebike batteries mainly use power cells with high discharge rate. If your motor power is very high, and need ebike range for a long time should choose Samsung, LG, Panasonic and other high capacity high discharge rate of 3500mah 18650. usually Chinese brand 18650 cell capacity and discharge rate is lower.Please contact us for details and we will recommend the best cost effective battery solution for your situation.
Our battery cells are all brand new A grade. We strictly select cells with the same voltage and internal resistance and capacity to form the battery pack before producing the cells.
Before production we check that each cell is in good appearance, in addition we use 100% brackets to hold the cells in place during cell production to keep the cells free from crushing and good heat dissipation. The new 18650 top is with pressure relief safety valve to stop the fire and explosion caused by short circuit and overheating of the cell.
For a quick quote, please let me know your motor power, battery type, and battery parameters. We will reply quickly within 8 hours. Thank you very much!
