Hi I’ve got a question about my charger the hi tech mutlcharger x4. Whenever I put in a certain charger cable with a nimh sc2500mah it says reverse polarity what do i do to fix or is it unfixable.

These are the connectorsSounds like you may have it plugged in backwards. Are you matching red to red, black to black? What kind of connectors are you using?
I did that and it is currently charging it worked thank you!It looks like your red plug and black plug are mismatched.
Make sure the red wire is connecting to the red wire and black to black.
Well I got the charger cable from hobby bench a rc store told them what charger cable and gave me that one. It’s currently charging right now I matched the red and black wire together.Those two plugs are not the same plug and are not intended to be used together. The black plug is a futaba connector and the red plug is a JST-RCY connector. You need an adapter. LINK

Those 2 plugs are not matching plugs. I mean you can force them together it will charge since both plugs use the same connector pitch but those are not meant to go together and the futaba connector is going to get stretched out.I did that and it is currently charging it worked thank you!

Is there ones with banana plugs to them? I have found one but I don’t know if that’s the same. Also yeah the guy just handed me a cable I barely know about the cables. Was hoping he would know…Those 2 plugs are not matching plugs.

I'm hoping your hobby store person misunderstood what you needed otherwise hes an idiot. just sayin'
Yeah, those will work. Id also make sure to use a temp probe on the pack while charging it too. I'm assuming you're using a hobby grade battery charger? If you are then using a temp probe on your NiMH packs will lengthen their life span because your charger will be able to adjust the charge current according to how hot the pack is. Heat kills batteries, especially Nickle based packs.Is there ones with banana plugs to them? I have found one but I don’t know if that’s the same.
