First ride out I got 62 miles!
I got the Bafang 750 w conversion last year and am super pleased with that. I was using a no name battery that I already had, and it was pretty clunky. It died, so on with the Whale Shark! Easy installation with the included 40amp plug. Really appreciate the built in charge indicator. Time to hit the road!
Did a 50 mile ride using the Whale Shark today. The battery was at 50% when I finished… That means I can easily get 80 miles out of this battery on a day with no wind and no hills! Motor BBSHD.
The battery worked great as it was totally compatible with my existing battery mount that I have been using with a 17.5 Ah Jumbo Shark battery.
No issues and works as intended.
