I need your advice as I don't know how to charge my bike battery.
My bike was broken for more than 4 months, battery fail.
On warranty I've received a brand new battery but come with another type of DC plug.
My old one, left photo had female port with a male 5.5x21mm.
The new one, right side photo come in with male!? But I don't know what type of plug need.
Is not a RCA DC.
Anyone knows what port and plug is?
