I was reading the instructions for the battery i just got and it says charge each individually and not to charge 2 in serial (not sure what that means) But can i charge 2 at same time now that i bought the dual charging part?
The dual adapter is serial.
Google search trumps Wiki. Refer to user guide.
huh so I got the dual adapter for nothing?
I cannot speak for Venom batteries, but the EZ Peak Plus 6A will charge two Traxxas LiPos in series using either the 2s or 3s dual charge adaptor. The packs need to be identical. It also helps if they're run in a vehicle that uses two batteries at once so they're around the same voltage.
The charger basically sees one 4s or one 6s battery, not two individual packs. So if one is at a significantly higher / lower voltage it will spend a long time balancing the cells.
