I've been aware of the possibility of cell connection bolts loosening over time. There are ways to combat this, such as using braided straps and nord-lock washers. Having been reminded of these techniques by several recent YouTube videos, I thought I'd check my cell connections.
I've been cheap, as usual, so I've just used the plain copper interconnects supplied by GWL Power along with the bolts and washers which come with them. It's also been nearly a year since I put everything together, so I was interested to find out if they had indeed loosened. I had also noticed that the pack temperature does rise quite a bit while driving. No visible signs of extra heat were noticeable though.
Turns out not only where several bolts quite loose, I had even forgot to put in all the washers. So yeah, don't forget to check your battery bolts regularly, especially if you don't use nord-lock washers.
