-===== Control modes switching setting =====+====  Configuring the config loading with the CAN button ====  
 + 
 +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: \\ 
 +  - [[en:controller:examples#loading_the_config_using_the_on-board_computer_buttons|On-board computer buttons]]. 
 +  - External switch, connected to On-board computer. 
 +  - External switch, connected to Controller. 
 + 
 +==== Loading the config using the on-board computer buttons ==== 
 + 
 +This method is the easiest to set up, configuration loading is activated by one of the four buttons on the On-board computer. 
 +  - Make sure you set up and export the configuration to the SD-card to a file **NCconf1.cfg** — **NCconf5.cfg**. \\ 
 +  - For example, you want to load the configuration **NCconf3.cfg** on pressing the first button on the On-board Computer. Go to the **Controller** > **I/O configuration** menu section, then assign the **CL3** function to the **CAN port 1** menu item. \\ 
 +  - Save the settings in the menu item **Controller** > **Save settings**. \\ 
 +  - Go to the menu section **On-board computer** > **Button setup** and for the button **Hot key 1 func.** assign **CAN_1**. Button type **Hotkey 1 type** select **Normal**. \\ 
 +  - Save the settings in the menu item **On-board computer** > **Save**. Setup completed. Go to the main screen. Now by pressing and holding the first button of the On-board computer you will be able to instantly import the **NCconf3.cfg** configuration from the SD-card. After importing, you will see a notification with the name of the loaded configuration. \\ 
 + 
 +If you specifically do not save the loaded configuration in the Controller settings, then after switching off and on the Controller, your previous configuration, which was used before the import, will be automatically loaded.

 Three control modes are available in the Controller settings, for which you can make different power and speed settings. To switch modes **S1**, **S2**, **S3** you can use several methods: \\ Three control modes are available in the Controller settings, for which you can make different power and speed settings.

-===== Regenerative braking setting =====+==== Regenerative braking setting ==== 
  
 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.

   - Save the settings under the **On-board computer** > **Save** menu item. The setup is complete. Now, when you have **Mode S2** enabled, after you have pressed the brake lever and completely stopping, you can press the brake lever again within 4 seconds and hold it down to activate reverse. If more time passes between presses, the reverse will not be activated and you will have to press the brake again and again to activate the reverse. You will see **R** at the top of the screen when the mode is activated. To disable reverse you must release the brake lever, the controller will return to control **Mode S2**.   - Save the settings under the **On-board computer** > **Save** menu item.

 +==== Upgrading the battery ====
 +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:
 +  - 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** > **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). 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.
 +  - Test your setup at safe area to confirm battery power output!
