Seat tube batteries require less space and are usually installed under the bicycle saddle, as well as on the e-bike seat tube. Ideal for folding e-bikes, as well as small mini e-bikes, often used for family trips and commuting to work. It is also a great choice as a backup battery for different styles of e-bikes.
The battery is compact and light weight, the minimum weight of the battery is only 2.5KG, the battery is very suitable for installation in 24V 36V 48V folding electric bicycle and mini electric bicycle. The battery fixing base can be fixed on any round tube of ebike. It can be under the saddle tube, or ebike head tube, etc. The large capacity seat tube battery style is fixed under the saddle with rails and the battery is paddled into the rails to hold the battery in place. This type of battery can reach a longer driving distance and is often used for car valeting.
seat tube type electric bike There are three distinct ways to mount the battery.
The slide type has the largest capacity battery. Depending on the body size of the cells up to 91PCS 18650 cells can be installed. This style of cell is divided into top discharge and bottom discharge. The battery rail can be disassembled by fixing it to the ebike with screws. Battery disassembly requires adjustment of the ebike cushion. The battery has a security lock, after locking the battery will be fixed on the slide rail is not removable.
The battery housing is made of sturdy aluminum alloy and can be installed as a saddle down tube. The battery is perfectly integrated with the ebike, the disadvantage is that the capacity is too small. Commonly used to make 24V 14AH and 36V 10.5AH capacity. The battery is mounted on top of the ebike saddle or electric scooter handlebar. The battery is fixed in the ebike frame and can be adjusted for expansion.
Battery fixing base and battery two in one. The battery base can be fixed to any tubular metal of ebike. The battery is paddled into the base and then locked and fixed. Separate removal of the battery can be easily taken home to charge. Battery weight is only about 3KG. The battery capacity is medium, the appearance is small, as a mini ebike or large ebike backup battery, double battery is also a very good choice.
Depending on the requirements, you can choose a battery with the following functions
E-bike lihtium batteries level indicator light. Press the switch to display the current e bike battery level, when the power indicator only shows the red LED, it is necessary to charge the battery pack.
The power switch controls the operating status of the lithium battery pack. 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 Electric bicycle battery will be activated when the switch is turned on.
A Bluetooth-enabled BMS can be installed inside the Li-ion battery, and the batteries 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.
e bike lithium battery packs waterproof rating is IP650. ebike batteries 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 batteries.

ebike batteries can be manufactured using Lithium-ion 18650 & 21700 cells. Currently seat tube batteries pack maximum capacity is 24 V 38.5AH, 36 V 28AH, 48 V & 52 V 21AH using Samsung, LG, Panasonic and other 21700 18650 Iron lithium battery cells.

Down tube batteries can be customized with up to 60V voltage. We also have 60 V 52 V 48 V 36 V 24 V 12 V battery voltage. The higher the voltage, the lower the capacity.The battery voltage should be the same as the motor controller voltage.

The current Down tube type battery style can be installed in the maximum 40A BMS, the maximum continuous current of 40A. The common 500W motor is 20A current, 250W motor is 15A 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 batteries cells. China’s BAK,DLG,EVE,MOLI 18650 Lithium-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.
Batteries 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!
Don’t hesitate to inquiry today – all batteries are on special until 26 October 2023. Hopefully I will hear from you :)
