GWL has supplied more than 30 000 pcs of the Cell Balancing Module CBM1 board. Based on the user experience, we have found out that some customers have damaged the board when soldering the wires to the battery contact terminals.
There is a high risk of overheating of the components especially near the (B-) terminal. When you overheat the components, the board will stop working properly. This is not a product fault, but a user damage to the product. No warranty can be applied.
Be careful not to damage the CBM1. In addition, there is also a risk of the damage to the components by the electrostatic discharge. Please protect your CBM1 against any accidental damage.
