Problems charging lipos
I'm just got a few new lipos (below) and I'm am having some issues charging them.. it am using the ascend radiant charger and it have charged lipos with no problems with it. But with these two battery's they just won't fully charge.. they charge for about a half hour and then it will say they are done.. when really they only have about 1000-2000mah in them. They last about 5mins max II have been looking all around the internet and have not found anything. If you know how to fix this it would be greatly appreciated. Thanks. (Also i am charging them at 1c)

All of my batteries have bullet ports in the hard case like your Venom batteries. I was using the supplied charging jacks with bullets on one end and female deans plugs on the other connected to a similar charging jack coming out of the charger with a male deans. I had put all new bullets and deans connectors on my charging leads, but I was still getting these strange false peaks. I even changed to a new charger because I thought something was wrong with my first charger, only to find the 2nd charger did the same thing.
I had a buddy tell me to use Alligator plugs to connect inside the battery bullet ports. I was skeptical, thinking that alligator clips make less of a contact patch to the port than an actual bullet does. I can't explain it, but the alligator connectors solved my problem. I've seen two other racing buddies go through the same issue at our track and the alligator plugs fixed their issue too.

Are you balance charging? What are the individual cell voltages when the charger says the pack is full?
