How to safely discharge batteries

The batteries make our life more convenient, as the electric power, we should use them safety. Last week, we talk about how to charge lipo battery, from the article you have learned charge lipo battery is not easy thing, we should take more carefully. Today, we will give you some advises about how to discharge batteries.

the battery fire

1. Don't discharge Batteries at amperage rates higher than specified on Batteries' labels.

2. Don't allow the temperature of Batteries to exceed 140°F during discharge. Adequate cooling for Batteries is required, especially when discharging at or near maximum rates.

3. Don't discharge Batteries to voltage below which they are rated by the manufacturer when measured under load (connected to the vehicle or a charger capable of discharge). Batteries discharged to a voltage lower than the lowest approved voltage may be damaged, resulting in loss of performance and potential fire when Batteries are charged.

4. Don't discharge battery to a level below 3V per cell under load.

For Tattu series batteries which are used for Unmanned Aircraft System, The recommended cut off voltage is 3.5V per cell.

5.Don't leave battery unattended during the discharging process. During the discharging process, user should monitor the process constantly and react to potential problem that may occur.

6. In case of emergency, discontinue the process immediately, disconnect the battery, place it in a safe area, and observe it for approximately one hour. This may cause the battery to leak and the reaction with air may cause the chemicals to ignite, resulting in a fire. A safe area should be outside of any building or vehicle and away from any combustible materials. A battery can still ignite even after one hour.

7. User need to check the conditions of the battery before use it or discharge it. Stop using it if user found the cells are not balanced or cells are puffing or weeping.

And finally, don't over discharge the battery, over discharge the battery maybe let the battery damage or fire, so please take more carefully to discharge batteries
