Switching to a 36 volt system so where can I get another cable to connect the additional battery to the other?

you can find it at an auto or marine store or anywhere that sells wire

Thanks

I bought the cable at lowes and the 2 ends at a Autozone/Oreilys. Don't remember the size but it was thick, like pinky finger size cable- in red.

Thanks bugzout. Particular gauge?

Need to use 6awg, Boris Marine sells it for like 2.00 a foot and will crimp the terminals for you .

Awesome. Boris is where I'll go. Much appreciated

if youre closer to south arlington i can make you one. i have plenty of 4 gauge wire and ring terminals. would save you some gas and time.

Dimitri, I appreciate the offer but I'm just a few mins from Boris Marine.

no problem

I use welding cable, red and black, and keep battery connectors on the shelf.
