I know this was a while back, but since then I’ve gotten a bunch of my plans in place, and am at the point where I need to actually order some cells!
You’re right that 30Q and VTC5a are basically the same price now. Probably going to be fitting a 10s4p pack to my board. So would there be any benefit going for the VTC5a cells? I know I lose a little range, but don’t I also gain better braking and discharge? Though there’s only so much braking I could use before I get thrown off the board, so if the 30Q is already more than adequate at 4p then I guess I’ll go for them.
For an all terrain like you plan the 30q should be fine. With vtc5a you might have a bit less voltage sag, means you could still blast when you below 40% battery, but that’s just what I would expect from the specs I can get out of both cells. I don’t have a 30q pack, so unfortunately I can’t really compair real life performance.
And don’t worry about braking. You will have good brakes with either of them.
Further 3D modelling of cover designs. Though the NESE modules seem to be pretty strong by themselves, so I’m mostly aiming for splashproof and deflecting stones.
I may remove those spring-mounting loops for the nese, and instead mount the boxes using something like these.
Looks nice! What is the flap kind of thing? BTW, if you make the edges of the outer enclosure that thin, it’s going to chip.
BTW, In addition to the spring mounts, I have added 4P NESE style boxes that you requested to the thingiverse “thing”. There are 2 kinds of boxes: 1. It’s a single piece 4P+4P mount that is totally flat 2. Just a 4P mount with an incline end so that you can glue them together to make a 4P+4P box that better conforms to the curve of the deck.
They both utilize the vibration proofing standoffs. Couple of pics of each:

The flap covering the drop-through? I hadn’t gotten around to finishing the holes, but the idea was that it would be part decorative, part truck-riser, and part securing for the enclosure as it would have 4x bolts running through it.
It would mean that that section of enclosure could only be removed if the trucks were also unbolted, but I was going to try and design things so that the battery modules could be removed from the open end if needed, so that section of enclosure wouldn’t ever -need- to be removed.
Also trying to figure out how I want to bolt the stuff to the deck. I don’t want to have bolts going straight into the wood, as if I ever need to remove and replace components it might weaken the inserts and split the wood. Not sure. Was thinking of having permanently bolted-in mounting brackets, and then having the batteries etc bolted to those brackets. Might be unnecessary though. Also considering using the rubber vibration mounts, or just thick rubber washers.
Oh and the edge goes thin because it looks nice in the graphic haha. I may round it off a little so it doesn’t end up as a razor-thin edge.
Ahh awesome, I will take a look. However I notice the central piece is solid… but doesnt that need to be a continuous bar on the first pack in the series? (not describing it well, but here’s a picture)
The ‘8p’ bar at the bottom. I guess it can be done with a wire going around the pack though.
VESC - Probably going to get one of the newly updated Flipsky 4.20 Duals. Seems they’re (meant) to have fixed any capacitor issues now. The 6.6 would be better, but probably hugely unecessary for my needs, and not worth the extra $100. (or at least this is my thinking, by all means someone chime in with an alternative, especially if it’s cheaper!)
Remote - I want to have a fancy one, with the LED screen and all. Considering making myself a Firefly Nano. But in the short term, I should probably get a pre-made one so that I at least have something reliable for testing with. All the usual options though, I’m struggling to find for sale in the UK (at least under the names given on this site). Closest options are things like the Flipsky one for $50. Any thoughts/suggestions?
