 In the settings of the controller with firmware version 0.8.7 and newer, it became possible to instantly download the desired configuration from the SD card to the Controller by pressing a button. This can be useful when using several different batteries, so that when you change batteries, you can quickly load new settings without using the import and export menus. Or, if you want to quickly change the controller settings from low power to high power config. The configuration loaded in this way is not saved in the Controller upon restart, unless it is specifically saved in the Controller menu after import. To download, the SD card must be in the on-board computer and the number in the configuration file name must match the number of the function configured in the Controller. You can use several methods to load the configuration: \\ In the settings of the controller with firmware version 0.8.7 and newer, it became possible to instantly download the desired configuration from the SD card to the Controller by pressing a button.

 It is instructions for Controllers with firmware v7.18 and for the On-board computer with v0.60B. If you have firmware v0.8.4 and v0.71B respectively, and a brake lever connected directly to the On-board computer, you need to set up a brake lever setting in the menu [[en:display:start#control_setup|section]] **On-board computer** > **Control setup**. Regeneration allows you to brake with an electric motor and charge the battery. This function cannot be implemented on geared wheel motors. It is instructions for Controllers with firmware v7.18 and for the On-board computer with v0.60B.

   - To set the regeneration level, [[en:controller:setup#electric_brake_setup|go to]] **Controller** > **Control modes** > **Braking phase** and set up the level of phase current of braking. If you have a scooter, you can start with **20A**, for an electric bike you can start with **50A**, for a Sur-Ron with **70A**. Next, test the settings and, if necessary, increase or decrease the phase current to achieve the desired result.   - To set the regeneration level, [[en:controller:setup#electric_brake_setup|go to]] **Controller** > **Control modes** > **Braking phase** and set up the level of phase current of braking.

-Upgrading the battery is pretty simple but sometimes needs a bit of calculation, because not every battery manufacturer provides complete specifications.+Upgrading the battery is pretty simple but sometimes needs a bit of calculation, because not every battery manufacturer provides complete specifications. You don't need to run full motor setup when changing battery.  
 Follow these steps: Follow these steps:
- - First understand your battery maximum continious 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.

- - 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.
