So after monthes of wandering and reading (as a guest tho), days of parts harvesting and hours of soldiering my board is (almost) finished. But obviously it doesn’t turn on… Well i have a led flashing once on the esc and the power switch, and then back to nothing.
Well let’s start from the beggining : i got a cheap board from internet something cold Helvei Smartmove (for like 250$). It’s basically a rebranded Liftboard dual motor, as far as i could tell, which is pretty similar to benchweel but the esc and bms seems different. Out of the box everything worked just fine, even though i tryed it like five min in my kitchen.
Because i had to travel by plane, i could not take the battery (nor all the big things) so i dismounted it and let behind the battery, the deck and the metal enclosure.
i don’t really now what motor it is but they are tagged as 2*900W belt driven The battery was a 6s4p (22v 8.8Ah), i made up a new one from an electric bycicle one, so i now have a 6s2p (22v 13Ah) with big flat cells instead of classic samsung accus. The BMS was a bit weird to me because the negative battery wire was a small red wire among the whites balance ones and not a big and sturdy one. Plus it seems like a custom thing with two spareted board one over another, and it has in addition a specific 5v (i guess because when i test it, the voltmetre stay blank when the esc is off) out for the controller.
The motor and mechanical parts looks good quality as much as i could tell, the blets are tight and everything seems good and new.
The ESC seems a lot better than most of the chinese or RCcars one i saw on the net (big and clean) you can see it on the pictures bellow. I didn’t find any similar one on the net so far, and i’ve been trying a lot.
So basically i did all the mecanic, i did all the battery and soldiering thing (even if the esc was looking weird i got a good 24.4v out of the battery and a stable 21.6v out of the BMS), plugged everything… When i press the button, one led on the ESC (see the pictures) and the button itself flash red (like really quick, a third of a second) and then back to nothing. I thought it could have been the “5v” input which didn’t seems to work, but i tested it while clicking the button: it seems to get alive for the flashing time but not long enough to get an actual reading.
I spent the day plugging/unplugging, resoldiering stuff and looking for ints over the internet, but still the same.
I don"t know if the ESC is fried, but the flashing thing makes me hope it’s not. It could be the battery also, but i don’t know how. (i tried pluging it to the charger, it says green and nothing happens, but i’m pretty sure the cells were all fully charged before i made it so it doen’t mean anything) I doesn’t have an other one to test.
I hope one of you could have a int of what is the problem or how to test it up… And if you think that the ESC is definitely fried, which one could i get on a budget ? (already went to more expenses than i thought buying decks and batteries…)
