Battery wiring.
 

Ok so i had to rewire some connection in my gun. The battery im using is an 8.4v 1400mah large battery. Now, I was wondering, does the red wire go into the round terminal and black to square, or is it the other way round. I rewired the thing wrong 3 times already and I really dont want to have to do it again.

red-round/black-square

ok thank you, I was told that, but then told to make sure because large and small are different. thank you

yeah, i had to learn the hard way too. mini and large connections are different.

Hang on there guys, I was sure the red goes into the square of the large connectors, but I didn't want to reply until I checked out both the batteries I have here with large connectors as well as my stash of cut off large connectors (to solder on Deans Ultra plugs) and every single one of them has the red on the square side, not on the half round side. Mini Tamiya are the exact opposite, which is a pain in the ass because of all the adaptors wired into stock AEGs to make removing the mechbox easy without having to rip out all the wiring. If you go by the mini connector adaptor in your stock gun, it's wired up the opposite of what your large connector should be, and the result will be blowing the output fuse on your charger (happened to me a few years ago when I accidentally used the mini connector polarity to wire the large connector on).

Get Deans plugs. Less hassle all around.
