Hi Have built my apple tree 80l into a dedicated foil assist using flipsky 6384 motor with the waterproof 150amp vesc running on 50p 12s3p. It runs well I’m 95kgs and I tested on the UHA870 with the 170surf tail
It ran really well heaps of power maybe could be backed off a bit but as voltage dropped to lower if I grabbed too much throttle the motor would skip or cut out slightly I would have to be very smooth on throttle response is there something in programming that I could change or is it that the system telling me that the battery is reaching voltage cut off of 3.2v.
All epoxy filled, you can maybe see the 5mm hole on some of them. The way I’ve designed them the connectors click into place, I 5 minute epoxy the connector in place so it’s sealed before filling with regular epoxy. TPU seal between male and female connectors works very effectively.
Those connectors look great! I’m currently on a 3 phase wire connector rabbit hole. I assume the yellow connectors are the AMASS MR30? They are only rated for 30A burst and 15 continuous, is that ok for 12S?
I reeally need to disconnect my mast, currently hard wired from ESC to motor and The board is taking a beating from the mast and motor while transporting.
FOC
Battery current 42.5amps
Motor current 100amps
Max Current 135amps
Wattage 1575w
Battery cutoff start 37.09
Battery cutoff end 34.36
Positive ramp 1.6
Negative ramp 0.25
erpm 30000
duty cycle control
This gives a pretty linear power delivery across the battery range 12s3p, can get a 40l board going with a 900 foil at 75kgs
normally when i hit the cutoff voltage it just looses power no skipping or cutout,
All good fellas more info the better I believe.
I’m using XT90 for the amp rating. Your plugs do look great but I’m a little worried on amp rating as well. Can I get the file for them please I’d like to give them a try.
Cool build! How is your hatch holding up, does it leak at all? Where did you get it from? There are so many options for those circular hatches, not sure which one to get.
try getting one where the seal gasket is on the hatch itself, and not the lid that comes off an on. osculati makes some good ones but hard to find in the US
I just bought this hatch from local BCF camping store nothing special. I haven’t had leaks from hatch but I did get a leak because I ran Rx wire external to top front of my board which leaked a bit I’ve fixed with silicon.
