I checked the battery everything looks fine but it won’t charge 
The charger has the full charge green light and won’t turn red
Was it charging before? Is your battery liion or lipo
Liion i can’t make sense of this hehe
It may be wrong cell order, or a faulty charge port
It’s the second charge port
Not sure what is going on here…
Neg charge port lead goes to p- B1 on the bms goes to the neg batt terminal Pos charge port lead goes to the positive batt terminal.
There are no other connections to make other that your balance leads.

I will start with a charger, where do I buy a good 12s charger
I believe TB has a good one, but any 50.4v will do
Ok I just ordered another because everything on the battery seems fine
Thanks everyone for the help
Had a prob like this just the other day, turned out one wire on the b- had come loose. I spend about an hour checking everything until I finallly found the broken solder joint

I doubt this is a charger thing. Most likely a loose connection somewhere.

Check continuity to ground from your charge - cable to battery ground. Do the same for the positive wire. Go from there
Ok I’ll do that because when I connect the charger and check the ables 50v are going though Could it be a lose connection on se negative on the battery to the bms
