Re: BOSS LEVEL CUSTOM SPOT WELDER

Hey Aulakiria! Got your Boss spot welder just the other day and about to test. I have more 4s packs than 3s... Can this use 4s Lipo instead of 3s? I'm charging an old 3s now, but not sure how long it'll last to be honest only a 25c 5000mAh zippy. Fast shipping and seems really well made from first i...

Re: MARBEL ELECTRIC SKATEBOARD

But this sucker is getting cracked open the day the warranty expires! New grip tape at the same time (love Vicious grip). How does it ride now? I'd love a set of th...

Re: CC licence and VESC

If you build a similar "widget" as someone else, and use different components, with different features... even if the schematic is roughly the same - does CC apply?

Re: Need advice on electric longboard Project

a couple things. Trucks - cool hollow trucks, but you won't find a mount that works with them. Plus the shape is going to make it really difficult to fab your own mount if that's what you want to do. I would instead stick with the "tried and true" Caliber II 50's, or Paris trucks. The paris trucks a...

Re: Anti-Spark Stuck On From Charger?

Bruno is typically really great about warranty support. This is the long PCB one w/ 2 or 3 FETs? As i understand it - the FETs take a beating at power on - so when they fail they fail "open" - passing current all the time and no longer work as power switch. Depending on the Mosfets used (FETs) - the...

@flangefrog - is there an advantage or disadvantage of mounting the FETs on top or below the aluminum (yours is copper)? Also curious on the copper you used - dimensions? That looks super clean.

Re: Can I still push an e-skateboard?

MagiicHat - i was going to suggest you look for the DIY hub build. I think the challenge you might find is getting a low enough kv motor to use in a hub. I'm not sure if they are rewinding for lower kv, or more likely buying lower kv from the factory custom wound, but most seem to be 80-100kv now. GL!

Re: Can I still push an e-skateboard?

I'll bite. I just pushed a few blocks back when my Marbel motor gear spun off. I had no problem pushing and riding it with the power off. The up hill sections sucked, but they would suck on a regular board too. Yes there is additional resistance vs a non-motorized board. But not horrible. small down...

Re: DIY Electric Longboard Build (Plan!) - Can you confirm i

Hi Njakts May I suggest you do it another way that may well be cheaper and, IMHO, better? The 97mm wheels are, in my opinion, great. A set of 90mm wheels would be more expensive than changing your wheel gear. If you made that a bit larger then you would reduce your speed and increase your torque - ...

Lemon - i'm pretty sure you are going to set this up poorly and be really dissatisfied. 4s is going to have very little power - especially w/ 270kv motor - it's going to cog/stutter a ton to start.

More power - which you need to move a human vs RC Car. 6s would be the minimum i'd recommend. It w...
