 Follow these steps: Follow these steps:
   - First understand your battery maximum continuous discharge current. If your battery have only kW rating then divide it by nominal battery voltage, for example 25000W / 72V = ~350A.   - First understand your battery maximum continuous discharge current. If your battery have only kW rating then divide it by nominal battery voltage, for example 25000W / 72V = ~350A.
   - Go to **Controller** > **Battery** > **Discharge max** = Setup 350A or other value specified by battery manufacturer.   - Go to **Controller** > **Battery** > **Discharge max** = Setup 350A or other value specified by battery manufacturer.
   - Go to **Controller** > **Battery** > **Charge max** = Set value specified by battery manufacturer, if not available use 1C rating of your battery, for example if battery 40Ah then setup 40A.   - Go to **Controller** > **Battery** > **Charge max** = Set value specified by battery manufacturer, if not available use 1C rating of your battery, for example if battery 40Ah then setup 40A.
-  - In same **Battery** menu or in **Autosetup** menu (depends on firmware version) select **Cell count** and **Battery type**, for 72V it is usually 20S LiIon (check battery specs).+  - In same **Battery** menu or in **Autosetup** menu (depends on firmware version) select **Cell count** and **Battery type**, for 72V it is usually 20S LiIon (check battery specs). This will setup your battery minimum and maximum voltage, so you wont have to calculate it.
   - Go to **Controller** > **Control modes** - choose your highest power mode, for example mode 2, and change **Battery 2** parameter to your nominal or peak battery current, in this example to 350A.   - Go to **Controller** > **Control modes** - choose your highest power mode, for example mode 2, and change **Battery 2** parameter to your nominal or peak battery current, in this example to 350A.
