Help with Rad Runner 2

[all1wordla]

Hi. Bought a used RR 2 on Craigslist. The guy said that he modded it up with a new external battery to get better range (took out the original one). The charger he gave me doesn't work. And now he's ghosted me. (Theres's no info on the battery that would lead me into getting the right charger).

My question is: Can I just get a new after-market battery and do it that way. Any suggestions for the battery? Would rather not break the bank on this...

Thx. I'm a total noob.

Take some pictures of the battery, any label (clear picture) and the charging port and maybe someone here can help point to a charger vs a new battery. And also maybe pictures of the mods. Also pictures of the charger and the label. Upload pictures here.

Thank you so much.

I've attached some pics (the big honking battery; it has a handle that you carry it by)), the charger (when I plug it in to battery it just stays green; the same as when the charger is plugged into outlet, but not battery); pic of the two wires into the bracket); pic of the wire that goes out of the battery into the controller I'm assuming (2 pins)

If anybody has idea for which chargers to buy / try, that'd be awesome. If not, then maybe best battery to buy to be able to use the bike.

Thx again!

Regarding your existing charger "staying green". It's going to do that if this battery is fully charged. The right charger should shut down at that point. The only way to get any idea of what you have going on would require that we know the exact voltage level of the battery.

Thx for your reply. Any idea how to find the exact voltage level of battery (it's like a black box from an airplane... totally sealed with rubber and no markings on it).

Thx again.
