    Battery charger

    I just finished my ride with 15% battery life. I went to charge it 5 days later with 3% battery life but the charger doesn't charge. Its cycles from green to red . Has anyone had this problem ?

        Did you find the troubleshooting section for Surron battery charging problems,it had several things to try.It does say that doing the battery charger trick can take 20/30 tries

            What's your voltage reading on your battery at the supra connector?

              You won’t get a true reading until the Bms wakes up.Does your headlight come on when you turn the key?When the light is on ,for a few seconds after disconnecting you can get a reading on the Supra conection.It will continue to drop voltage as the capacitors drain.

                  Do you have the dongle that plugs into the small battery plug?That might give you a trouble code.

                        I did increase my battery3 % to 6% after doing the battery on and off process. But still not charging like normal.

                          Your cells are probably out of balance with some under the lvc for the Bms,I would try to get it higher by doing what your doing until the low cells start excepting a charge.My first Surron battery that got water damage that corroded the cell strips and caused the charger not to except charge.Mine is not an isolated case,as my replacement had internal corrosion to,now I wash my bike minus the battery.

                            Great to know; remove the battery before washing!

                          Were your battery replacement under warranty ?
