I’ll try waterproofing my Flipsky vx2 remote that i bought but never used so i thought i’d describe it. I found suprisingly little info on the VX2 here and elsewhere, hope it’s still worth the effort.
First issue: charging doesn’t seem to be regulated properly, already after 1hr of charging it’s at 4.22V. For the longevity of the battery it should’ve maxed at 4.15 or even 4.1
I’ll leave it on and see if it goes above 4.25, if so, then it’s a dangerous design.
If it doesn’t, then might be worth to waterproof. This is the insides, read on esk8.news that it’s the same pcb as the VX1 remote.
