E-skateboard motor burned out, what are my options? Can't get spares

Hey folks, So a few years ago, I bought a SkateMaster UK-branded board and modified it to use li-po batteries instead of SLAs . It actually worked pretty well, but I got relatively little use out of it before, during a trip to work in 2017, it stopped working and smoke started escaping the motor. I ...

Re: Hacking a SkateMaster (UK) board - help needed!

Well, it's been a very long time. I have actually been using the board as much as I can - it's been working very well with my idea to use the charge adapters and a parallel board. Charging is a simple matter of unscrewing the watertight box on the side of the battery carrier, connecting the main, ba...

Re: Hacking a SkateMaster (UK) board - help needed!

So, been a while. I haven't given up with this board, but the UK summer has given up without a fight and I've struggled to see decent boarding weather. Thankfully the controller wasn't fried. Surprisingly, the broken positive wire didn't short all the way through - there was still continuity. Still ...

Re: Hacking a SkateMaster (UK) board - help needed!

Shit shit shit...! I connected the 4 batteries up minus the charge alarms, and sure enough got only a small spark when 24V was applied. As the board stops running long before the cell voltage drops to dangerous levels, I didn't bother with the alarms. However, I got halfway to work this morning and,...

Re: Hacking a SkateMaster (UK) board - help needed!

Okay guys, I think I was right about the charge adapters. I didn't realise they bridge the batteries into series - the central pin in the seven-pin 6S connector is connected to both the positive end of the first battery and the negative end of the second (taking GND to be of the first battery). I tr...

Re: Hacking a SkateMaster (UK) board - help needed!

Ugh... that drawing doesn't help me. OK, looking at it again it makes a bit of sense... As for your friend who says that looks normal needs to not ever touch electronics again... that isn't spark that's WELDING. That is a short and mine looked almost identical. Smoke and black/melted is not "spark"...

Re: Hacking a SkateMaster (UK) board - help needed!

Gargravarr - sounds like a short to me. I'd quadruple check your + and - ... I had similar happen to me one time and turns out i flipped one of my xt-90's i soldered onto the ESC. Fried a couple connectors before i stopped, double checked, and finally found it. D'oh! moment. The spark you should se...

Re: Hacking a SkateMaster (UK) board - help needed!

The charger wasn't giving an error code, just trickle-charging until it hit either the capacity or time limit. However, while trying to get a photo for RMA'ing the pack, the charger decided it would fully-charge it this time. I've had all 3 cells reading 4.20V, so I'll give it the benefit of the dou...

Re: Hacking a SkateMaster (UK) board - help needed!

Quick question - I bought a pair of 5,000mAh Flightmaxes and ended up using them (before giving them a full charge) when the board ran out about half a mile from home on Friday. Although I didn't use them much, I think one of them is giving me trouble. Whilst one of the pair charged up fine, the sec...

Re: Hacking a SkateMaster (UK) board - help needed!

Well, I was able to use the board only once more last week, and again it ran out very quickly about half a mile from home. The hills must be killing it quickly, but at the same time, I was expecting >10 miles range with the 7Ah stock batteries. Sure, these have gone down to 4Ah, but I would hope tha...

Okay, progress. I got it working :D http://i342.photobucket.com/albums/o432/quantumleap2032/Skateboard%20Hacking/P7060347.jpg I ordered some HXT-XT60 adapter cables plus some XT60 plugs and sockets. I painstakingly removed the original power connector and soldered on an XT60 connector instead. I als...

Re: Hacking a SkateMaster (UK) board - help needed!

I was more wanting to know if it should be sparking with the board's power switched off, especially since I can't see any obvious shorts or crossed wires - could it just be to do with the voltmeter? Again, I really don't want to short this thing out and be left with a smouldering crater where my boa...

All right, photo time gents! http://i342.photobucket.com/albums/o432/quantumleap2032/Skateboard%20Hacking/P7020336.jpg This is the board itself, with my 360 controller shown for scale. Bit of a beast, I think, although I've never seen another in the flesh. http://i342.photobucket.com/albums/o432/qua...

Re: Hacking a SkateMaster (UK) board - help needed!

Well, I took the battery case down to Maplin at the weekend and their Yuasa 7.0Ah batteries are a perfect fit, so I'll assume the stock batteries are about the same power. I'm wondering, from a cost point of view to get this thing working, whether there's anything to be gained from buying a pair of ...

Re: Hacking a SkateMaster (UK) board - help needed!

Thanks for clearing that up sl33py, great help! Remember what I said about the stock batteries being Chinese junk? Guess what, they're labelled in Chinese as well!! I could unsolder one of them and compare it to similar batteries on sale at my local Maplin store to get an idea, but I can't find anyt...

Hacking a SkateMaster (UK) board - help needed!

Hi guys, Brit and skateboarding n00b here. I've been hankering after an electric board for years, after discovering xkcd author Randall Munroe is a big user of them - this despite me never having ridden a board before, btw. So, I finally took the plunge last week and dumped £85 into a Skatemaster bo...
