Chosen Solution

So i assembled almost the whole thing but when i tried to plug the battery wire into the port it wouldn’t insert so I looked up the model and it turns out that i got a 6s battery kit instead of a 6 battery kit. So I was wondering if i take out the battery can i send it back for a return, or not.

If it was already glued in place with biadhesive I’d say no, nobody would replace or refund a used battery.
