i think xt30s are rated around 20amp or something iircā¦so all good thereā¦ plus so small and tiny too!

Any idea how to waterproof them? I was thinking if I epoxy the male end into the enclosure and seal with silicone, and tie some paracord through the female end and flood with silicone then it should be a water proof loopkey-like plugā¦but Iām not sure its good enough
I donāt waterproof the jack itself, just make sure water canāt get past the jack.
The high-voltage circuits are less affected by water than the low-voltage ones. If it filled up with water it might waste a few watt-hours of charge but overall shouldnāt be too bad.
You do want to keep sand and other debris out though with a cap
Same goes for phase/sensor wires, loopkey, and voltage display?
I mean Iāve seen people go through a lot to make the enclosure waterproof so I donāt see why youād skimp out on a port
Strip the metal pins out of an extra connector and seal with silicone. Works like a cap/plug

How do you attach battery holders to a deck? Can I hot glue the holder or double side foam tape?
I wouldnāt recommend either of those. Both hot glue and double sided tape have thermal limits, and hot glue also gets weak and brittle in the cold. Iād recommend screws if possible, or epoxy (both surfaces sanded rough), or maybe a urethane construction adhesive like liquid nails, as long as youāve tested it for strength and compatibility with the materials itās sticking to. You want the absolute strongest attachment you can get, with some flex.
Imagine taking the completed board and slamming it on the floor as hard as you can for an hour straight. Thatās the kind of abuse an esk8 takes from vibration, so construct accordingly.

Are you talking about attaching the battery to the deck or the enclosure. Battery I would use industrial strength Velcro for the enclosure I would say threaded inserts and screws. What type of enclosure do you have?
Itās a temporary rigā¦a brushed DC motor from an original metroboard/fake 30Q batteries in plastic holders/sheet steel enclosure thatās clamped between the deck and truck spacers
I have one of these old adapters for dual focboxās 
But then I ended up getting a unity, so my question is can I use this adapter to connect the unity to my battery pack and just leave one of the connectors open? Or would this cause any problems?
Theoretically, it should be good, Just make sure that you isolate the contacts of the xt90 connector you are not using properly. 
If you have a 3D printer you could print something like that:

Guys, while we are talking about charging. I have 3 x 42v chargers (1.5a, 1.8a, 3.5a) and I took a multimeter to them. Not one of them actually measures 42v. They range from 41.5v to 41.9v
Is that normal behaviour? Is it something to do with cc-cv charging?
Not that I really care but I am worried that the bms doesnāt kick in at all to balance the cells at the end cos it never hits 42v 
Any good address in France or EU for a focbox fix/repair, please gentleman ?

I used crap quality brass inserts for my enclosure, and now one of them has the threads strippedā¦ Any ideas on what to do? Need to replace it with a new one, so I canāt just drill it out since the new insert wonāt have anything to grip into. Guess I could fill the hole with some filler if drilling is the only way out
Use a tap and rethread the insert
You need to get it out of there. Use a sharp drill bit that is smaller than the outside threaded section but big enough to remove the inside core. Once you have drilled it then use a small flat bladed screwdriver to wedge out the outside threaded section from the deck. If you get it right the wall of the insert will be thin enough to break away from the deck and leave the outside thread cut into the deck intact. If you get it wrong you will have to up the size of the new insert.
Also if you have the inserts with the part that looks like a flathead screw drive would go in if that was screwed in faceing out you should about able to slowly back it out using a flat head.
What is on the vereal batteries? Xt60 or 90s?
