Why does the battery indicator shown 84% for BBSHD motors?

Lots of customers used a 52V battery to connect with a 48V30A controller.Then the display might shown high voltage error 07. So BAFANG has update the 48V30A controller to 52V28A,then it can compatible with both 48V and 52V batteries. For a 52V battery it will show 100% on the display when connecting to the 52V controller, but for 48V battery,it will show 84%. We're still trying to resolve this matter,it's not a big question, it won't effect any fuctions. SOLUTION:

Step1. Buy a program cable from us, here's the link: There's a youtube video down below for how to use BBS/ENA PROGRAM CABLE.

What's the difference between MAX-CARGO and G20-CARGO?

1) G20 use Dapu mid motor, MAX-CARGO use TSD rear motor, not famous and more cheaper.

2) The Dapu smoother and better on hills than TSD rear motor.

3) The twist throttle vs. thumb throttle- just different.

4) About the display, 500c colorful display is more better than CDC-6,CDC-6 is also great.

But you know the motor of MAX-CARGO is more cheaper so we could use 500C on it.We want to balance two Cargo ebikes.

5) Max Cargo have regen braking and not in the G20 Cargo.
