I have a problem with my EZ Peak Plus and my Venom 3s batteries. If I check the Venom battery with a cell checker, I get 11.4 total, 3.8, 3.8, 3.8. If I try to balance charge, I put in 3 cell Lipo, and it confirms 3 cell LiPo and starts to charge for about 4 seconds, then says low cell voltage. Then the EZ Peak shows 3.8, 3.8, 3.8. 1.9, 3.8, like it is a 5 cell battery with a bad cell. It happens with both of my Venom batteries. They are the only 3 cell batteries I have. The charger doesn't have this problem with any of my 2 cell batteries. It will charge fine if I take off the balance plug.
I wouldn't take off the balance plug, no. I would call Traxxas... could be a dirty socket on the charger or a faulty solder joint internally.
Whatever it is I just typed... could be wrong.
I'll give them a shout.
there not gonna help U if ya tell em ure not using traxxas batteries.
