So I am at the very end of my Ryca CS-1 build. Going through the process of starting the bike up for the first time in months, taught me one thing about compact lithium batteries (Ballistic Evo2 4cell). They have very small power reserve! It was not really a surprise to me, I knew what I was getting into from the start.
I ended up draining the battery a few times in attempt to fire up the bike, and I also learned to hate removing my seat to access the battery terminals to charge it. My solution is below, best part is that it cost me $0, just a few random parts around the house.
Bike side. Connected to positive terminal and tucked away inside battery box. The end provides good protection against any unwanted metal touching it.
Charger side. Clean solid connection can be made to the little dongle on the bike side. I left the standard 3 prong AC end because my charger can clip nicely to it.
Connected.
I haven't actually tested it with the charger, but I have tested with multimeter and there is good conductivity between both ends.
Parts used:
- A common desktop PC power cable. (This has 3 prong AC wall outlet on one end and female side of the coupler on the other end.)
- Male side of the coupler. (A little less common to have laying around, but can be harvested from a dead power supply)
- Ring connector
- Shrink tubing
- Electrical tape
Let me know what you think
