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.
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.
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.
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.
The battery pack discharge port is connected to the battery fixing base plate. Different discharge connectors and different lengths of discharge cable are available. The discharge connector is connected to the motor controller and thus activates the entire bike and brings it to life.
We can customize Electric bike battery and chargers with your LOGO and become your agent battery factory. We can also send batteries to your customers instead of you, which means you can sell your E-bike batteries worldwide.

The current Down tube type battery style can be installed in the maximum 50A BMS(Battery Management System), the maximum continuous current of 50A. The common 1KW motor is 30A current, 1.5KW motor is 40A current. The higher the current, the stronger the power, but also very fast power consumption.
The battery comes with a base ebike tube mounting plate for screwing to the ebike tube frame.This battery is flexible and can be installed in any part ebike tube
Battery fixed ebike tube kit hidden in the tube frame, the battery can be well hidden inside the ebike tube.This makes the ebike look very beautiful and the battery is well protected inside the ebike tube.
Additional battery frame is fixed above the ebike rear wheel. The battery is fixed on the frame, battery with tail light.The battery is removed by sliding it out through the base rail.
ebike seat under the base fixed battery, the battery can be removed from the base, can be fixed in any ebike round tube part. Another ebike seat removal method is to slide out from the rails
For a quick response, please let me know your eBike motor power, E-bike voltage, eBike controller current, and the battery capacity you want to order. thank you very much!
