The Electric Bike controller comes with label for each wire. It describes what is this wire for. Their connectors are designed to match as long as its an item from our E-Bike controller set. Your Controller can be upgraded to different currents. Please contact us for more information.
I am delighted with this battery and the contact I had with the company beforehand to ensure it was the correct replacement. It came with a new mount and rack, and although there was no fitting instructions I was able to remove the existing mount and rack, access the existing wiring by removing a plate below the mount, and then the new 4 pin terminal mount was easily connected (plastic plate, terminal mount, plastic cover screwed in place and new retaining bar) with the bullet terminals on the wires. Be careful to match the polarity of the battery with that of the terminal. I have given 4 stars as I time will tell how it recharges but it does come with a 2 year warranty
Not very clear how to operate but after a number of attempts seems to be successful and will become a useful tool some instructions would have been useful
