well Mortymore i am glad that you are testing this out i do not have the proper testing supply to do it all i have is a multimeter and a few lipos and a old server power supply converted to a benchtop supply to power my chargers

i think each output on the receiver is 1a max so 2 a per receiver. also i remember reading the battery box has a 4a current limiter on it so it can run 4 m motors or 2 xl motors at the same time without cutting out

was just thinking that the controller side would be the one we need to protect because the motors can pull some good current threw those and i figure that they are over built just in case. in any case it seems to work find as it is with buffalo and me so i might just let it go and if it poofs just chalk to experience and get some more they are cheap to replace so its not too bad

if im reading the chips schematic correctly then the motors Voltage input is separate from the control that would enable us to keep the control part of the chip below 10.5v while allowing full voltage to the motors?

Thats the plan have a lipo cell checker that i can use to see what level it is when i go to use it. im going to get a second battery box to modify so i have a regular box to use in case of a dead battery or another model to power etc. do lego stores sell just the battery box or is it all in a set?

Well i just got down to it and did it. i have a 3 cell lipo battery that i use on my r/c cars it was at 11.5v when i used it and it made a huge difference in performance. much faster lifting and lowering of the boom and dont seem to load down as much. it what it should have been in the first place. Just fully charged the battery at 12.6v and it runs just fine so far going to have to get a smaller batter to fit into the battery box i think i can get a 950mah 3 cell to fit into the stock battery box just fine so it will not look out of place

Buffalo can you test the output on your 9.6v battery pack? fully charged it should be putting out more then 9.6 should be closer to 12v at full charge if the 9.6v pack i have here is not faulty

That makes sense im going to assume that it can take at least 10v because i saw someone on here with a 9.6v battery. anyone have some good pics of the inside of the receiver?

Well i just got the excavator set 8043 and love it so far just wondering what the max voltage that the power functions can take without frying? i was thinking about putting a 3 cell lipo that at full charge is 12.6v or 11.1 nominal this should provide some extra power for the motor so they wont bog as bad this site Here has tested the motors at 12v just really wondering about the IR receivers thanks in advance!
