Looking for info for replacement of Lishui LSW1155-29M controller

[larryvand]

Here are the specs of the Lishui LSW1155 controller:
Rated Voltage 48V
Maximum current 22A
Rated current 11A
Low voltage protection 40V
Throttle adjustment voltage 1.2v-4.4v

Since this controller fits inside the frame, any replacement must have same or smaller dimensions
Length=4.25 inches, width=2 inches, depth=1.125 inches

This LSW1155 controller drives only Lishui LCD displays. I would prefer the replacement to drive all Bafang LCD displays.

Thank you for your help.

This one is small enough at least
