I tried it in all modes & with several different battery sets. TBH the wiring job in the mod isn't the best, pretty thin gauge wires! The battery sled isn't top quality either

If this isn't a know issue, that some one knows about? I will strip down the board & try a Lipo, with proper gauge wiring

I have 2 of these mods & I got them for real cheap @ FT, so no big loss! I'm hoping the 250 is good thou. It seems to function normally? I'm hoping it's a battery config issue?
