The Etronix Battery Doctor Balance/Discharger is designed for Li-Po and Li-Fe batteries. It can measure battery voltage precisely and balance each cells’ voltage of a battery pack or discharge batteries in preparation for storage.

You can observe each cells’ voltage in the battery pack individually. This helps identify abnormal or failing cells during the charging or discharging process.

The balance function can be executed before or after the battery has been charged. It also can be done during the battery charging process, helping to ensure that the battery pack remains in excellent condition.
