About product
The Econo Tube M 36V 21Ah 756Wh battery is an electric bike battery assembled in Slovenia. It is designed to be mounted on the lower tube of the wheel frame. Attach the battery carrier with screws to the accessories for the bidon bracket. In the case of the battery, you also get two keys so you can lock it on the bracket using the built-in lock. The battery is compatible with 36V voltage engines.
The battery is located with a charger connector and a battery charge indicator. The 21Ah battery capacity gives you enough energy to plan longer trips in the countryside. The battery is only compatible with the original Econo charger 2A or 4a with a 3pin connector, which ensures greater safety and temperature monitoring during charging.
Easy to shake
The battery can be locked on the wheel with a key. We can charge it on or off the bike. We can use that in the winter when we feed it.
Long life
The Econo Battery Control System (BMS) protects li-ion cells from use in extreme conditions such as high temperatures, oversuspation...
Low self-discharge rate
Even after long storage periods. This means that econo rechargeable batteries do not need to be charged after a long break (after winter).
No memory effect
You can charge the Econo batteries at any time, regardless of the current charge level. Interruptions of the charging process do not harm the battery.
Outstanding cell performance
Samsung cells are perfectly balanced in terms of performance and reliability. They are very stable, even with the greatest effort.
Universal use
Econo batteries are compatible with a wide variety of engine brands, as well as with the implementation of the engine (central, front, rear).

Installation
Tube L is easy to shake. Installing the battery on the frame is the best solution, as the centre of gravity of the wheel is kept low and closer to the centre of the wheel, which also affects the control of the wheel. It can be installed on a wide variety of types of wheel frames.
Tube L and Tube M have the same base, so econo batteries with different capacities can be replaced on one wheel.
