As many of us, I got the Hailong battery for my soon-to-be eBike.
I was wondering how others are dealing with mounting it. I have square tubes with a bit of an an arc in it and the battery holder only has two places for holes. I can drill 2 extra holes in the bottom piece. However, then all 4 screws will be in-line and it doesn't feel stable for the long term.
How did you mount the battery?
