I've finished the first of the non-voltage-readout versions (ESJ-5AD).
One thing I did have to do is change to a 470uF 10V cap, which isn't a major problem. If additional decoupling is needed it will be better to be plugged directly into the RX with a VP470 or VP1000 unit.
Attached are some piccies
I've got two 2S lipos attached here but it'll work with 5 cell Ni, A123 or LiFe no problems.
