Technical Help

Batteries:

​

When you recieve your battery connect it to the charger.  See section below for charging.

 

Check your controller for short circuit before connecting your battery.  Failed controllers can internally short circuit and damage batteries.  If your replacing a dead battery or connecting a used controller, we recommend checking your controller with ohm meter before connecting your new battery.  If your ohm measurement across black and red ternminals is similar to touching meter probes together, do not connect your battery.  Connecting to short circuit can damage the BMS.
 

The BMS is a computer that protects the battery.  Do not reset your BMS.  Your BMS will protect your battery from; overcharging, overdischarging, drawing too much current and charging with too much current.  The BMS also protects cells from overheat and other conditions.  Since your BMS manages charging and discharging, you don't have too.  When your battery reaches the minimum voltage rating on the sticker it will turn itself off and it is time to charge.

 

The BMS continuously draws a small amount of power from your battery.  If you drain your battery and let it sit for a month or more, your battery voltage can drop below the minimum for discharging/charging and the BMS will not allow you to charge your battery.  If you have ANT BMS with Bluetooth connectivity the charge port can be forced on.

 

​Batteries with Bluetooth BMS do not require the user to connect with BMS to use the battery.  BMS connection allows the user to view battery voltage, cell group voltages, charge/discharge current as well as all other technical parameters used to manage and protect your battery.   To connect to your BMS,  check your battery sticker for BMS manufacturer and download the appropriate app

​​​

ANT BMS App for iOS & Android can be found here https://www.amdapps.com/.

JBD BMS App, search XiaoxiangBMS or SmartBMS Utility.

​

Open the app and connect to your battery.  If you have a ANT BMS, connect the battery to charger or draw current from the battery to wake up the Bluetooth function so you can connect.

 

When accessing the BMS the user should be careful not to inadvertently change any of the parameters.  Parameter changes void warranty.

​

Short circuit protection means the BMS will protect your cells short circuit but short circuit can still damage the BMS.  Often times if the battery is immediately disconnected from the short circuit it will not cause BMS damage.  The response time of the BMS is long enough that damage to the discharge port will occur and in some cases requires replacement.  Batteries left in short circuit will be damaged permanently and not covered by warranty.

​

Charging:

​

Charge your battery when you receive it.  Your battery should not be left empty for more than 1 month.  Batteries should be stored at or near full charge and should be recharged every 3 months to prevent under voltage condition.  Some batteries may be able to go longer.  If your battery is near the minimum voltage stated on the sticker it needs to be charged.

​

One red and one green light means your charger is in open circuit (charging complete)

Double red light means your charger is charging the battery

​

When the cell bank with the highest voltage exceeds 4.2v, the BMS opens the charge circuit to prevent overcharging.  After a short period of time the cell voltage naturally drops below 4.2v and charging occurs again until 4.2v is exceeded.  This cycle takes place until the cell holds above 4.2v.  Charge cycling at the end of the charging process is normal.  You may see the lights cycle as the charge process completes.​

Fardriver Controller:

Bluetooth Connection

Fardriver is compatible with both iOS and Android.  Controller must beep when powered on and bluetooth dongle must flash before you can connect with your mobile device.

Speed and torque adjustment

Speed and torque are programmable for each speed switch setting.  This means you can independently set max speed and torque for all three switch positions.  Kits come with instructions for torque and speed adjustment from your mobile device.  

Controller Restore and Reset

Controllers are programable for many different combinations of motors, throttles, and batteries.  If you purchase a kit, your controller was programmed for your specific combination.  If you reset or restore the program, you will clear the parameters needed for your controller to function properly and it will need to be reprogrammed. 

Autolearn

Autolearn must be performed to teach the controller the motor configuration before use.  Autolearn should be performed with the chain off and motor bolted down.  Select the Autolearn function from the graph page, after the controller starts to beep hold the throttle at full the entire time.  The motor will run rough and change directions during the process.  When Autolearn is complete your motor will stop spinning, controller will beep, and the app will show a throttle alarm.  At this point release the throttle and Autolearn is complete.  You can reassemble the chain and ride.  If during autolearn your motor stumbles and stops after twisting the throttle, release and try again up to 4 attemps.  After the forth attempt, swap blue and green phase wires and repeat.  Trying to ride before completing the autolearn process or after resetting the controller can result in controller damage.

Motors:

Motor shafts are left handed thread.

Motors can handle more power than rated if motor temperature protection is properly set in the controller.

The unused fourth mounting bolt is a pathway for water to be drawn in and should be plugged.
