Any clues what settings should be used on a Lipo compatable ProTrak? :confused:

Cheers Mark,

How do you know it's 3 cells?

The Pro-Trak does some voodoo magic stuff when you start to charge a Lipo to work out what the pack is, but at the end of doing that it says to me "check 12V or external fuse". When I press a button to clear that it seems to charge ok :(

it says 3S - this means 3 LiPo cells in series (LiPo cell = 3.7v nominal)

one cell is 3.7 two is 7.4 three is 11.1v

make sure that the prtrak will do 3 cells

Mark,

The Pro-Trak will only charge 2S :thumbdown:

Is this charger any good just for a TX pack?

looks like it could be, you need to make sure the plug on the pack matches the charger

this is a good un and it comes from your sponsors http://www.teamorion-avionics.com/Advantage+Chargers/Li-Po+Charging+System
