Thx!

some more pics

Thx everyone for help.   

thx.  having issues posting pics.  hopefully these go thru

The drama continues...

Took the battery off to try and find a sticker that would tell me the info so I could buy a charger (since I still haven't heard from the guy who sold it to me.).   Didn't see anything.   (I've attached a couple pictures -- he attached the new big battery to the post from the Rad Bike and wired it that way).

I now would just like to salvage the bike.   Is there a battery that I can buy and just wire in that way?

Sometimes I hate Craigslist.  

Thx in advance.   

Thx for the reply? understood a couple of those words and numbers. 

One last question.  Could I use a rad mission 1 battery on this?   Just pop it in?  Thx again

Thx for reply.   Sounds like job for my handy neighbor.   

Hi.  Bought  a rad runner 2 off Craigslist.   The guy who sold it to me swapped out original battery for a bigger one that he suspended under the rack (and is supposed to give better range).   

The battery won't charge with the charger he gave me.  (He ghosted me).   I don't see any stickers on the battery saying what the battery is.   Any idea how I can figure out the right charger to buy?   

thx
