the redcats use the simple molex connectors or tamiya connectors? idk which term is right, so i posted a pic with it.

A little blurry but it looks like Tamiya to me...

yeah its like that white connector thing. will this work in redcat vehicles?

it kinda depends which model redcat.
the caldera uses a tamiya, which is what you have pictured.

IIRC the 10th scale cars use the tamiya connector and the 8th scale cars use the Ultra Deans.

okay thanks guys so this battery will be compatible in my caldera 10E.

the conector is correct. how many cells is the battery? i dont know if the caldera can fit more than a 6cell 7.2v battery.

its a 6 cell 7.2v battery

it will fit fine. its nice to have more than one battery for such a fun truck as the caldera!

yeah and the good thing is, my backyard has got a hill, that 4wd will sure come in handy! too bad its not waterproof though or 4wd in the snow would be awesome.
