Daurema attaches importance to the ecological and recyclable aspect of its batteries, but also to the long-term satisfaction of its customers. In this context, this battery, which is manufactured in the Daurema production unit, in Belgium, is repairable and reconditionable for life .

Capacity and Autonomy

The capacity of the DA140 48V battery is 1460Wh , which allows you to travel approximately 100km in a cargo bike with a full charge.

Waterproofing and Durability

The DA140 battery is IP65 and resistant to splashes, as well as heavy rain. Its aluminum shell with interior foam gives it good shock resistance .


This model is seamless.

Current batteries include small lithium-ion cells welded together in a pack, which makes it difficult to dismantle.

Daurema has created a seamless lithium cell connection system, modeled on Lego blocks, with two printed circuits pressed against the cell supports, and a battery management system that clips onto the assembly.

This system makes the battery easily repairable and reconditionable, in addition to being safer and more reliable.

Connectivity and Installation

The DA140 battery has the following connections:

  • Charging/discharging: a single XLR 3pin male port
  • Wireless: none. No wifi, no bluetooth. Non-communicating battery.

The DA battery is easy to install. Simply position it in the bin of your cargo bike and connect the controller cable to the XLR discharge port.

When charging, simply connect the XLR port of the charger to this same port.


The DA140 battery is compatible with all cargo bikes that have the following characteristics:

  • Motorization: 48V
  • Controller: 30A max, XLR 3Pin female discharge port, non-communicating with battery

Check the technical data sheet and contact the bike manufacturer to confirm compatibility.

Buttons and Indicators

The DA140 battery is equipped with a 4-light capacity indicator. Just press the indicator button to display the battery capacity: 0%, 25%, 50%, 75% or 100%.

An on/off button also allows you to turn the battery off or on. It is recommended to turn on the battery only when in use, in order to preserve battery capacity.

Charger and charging time

A 48V - 4A charger , tested and certified, which does not overheat, is supplied with the battery. The charging time for a 1460Wh battery is 8 hours .

Second life cells & circularity

Daurema uses sorted reused cells , at 95% capacity, in good condition, verified and tested, from used batteries, in order to manufacture this battery with guaranteed capacity . This recycling allows each lithium cell to be used for longer, avoids their premature crushing, and therefore reduces the quantity of greenhouse gases released by the battery.

Repairability & refurbishment

The DA140 battery is repairable and reconditionable for half its purchase price .

Its optimized interior design made up of 3D printed parts allows for safe and rapid repairability .

Belgian manufacturing

The DA140 battery is designed and assembled in Belgium , in the Daurema workshops.
