Help needed for failing batteries

I need to make a new battery carrier. Any suggestions? I can put it on top of the board so I have lots of room. BTW. I just ordered a motor mount from you.

I will try changing the cut off as suggested.

@Erikkondo - You can use one of those waterproof enclosures on the top of your deck similar to the ones that you say EMTB’s using. Some of them are bigger and you can have a higher increase in height.

Sorry to bring this up again, but I am having a similar problem with 2 5000 mah 20c lipo batteries and it is driving me crazy. I have them wired up in series and had a charging cord also connected to them. The first set i had puffed up and then this set puffed up too. I saw that you are supposed to disconnet the cords after riding? So I am supposed to take apart the board every-time i want to charge? Thanks, Jesser722
