Charge skateboard with MacBook charger. Done

Never trust what you read. Some are 4 volts over.

Good point but out of curiosity, have you tested the life cycle on that? I tried something similar and gave up because near 50v I blew the cap on one module and another one lasted only a few hours. All the modules rated to 60+ were closer to the size of compact chargers

If you actually solder the xt-60 wires at a right angle in the cup, it looks like there’s plenty of room for mounting in two directions. Towards top/Side. Not enough room to rely on bending wires close to 90* after soldering straight into the cup terminals

I just hate xt 60 for this application. I could yes. We are talking less then an amp. :grin::upside_down_face:

I’ve done a 72 hour load test. Warm and happy

I realise the bulkiness of it, but if you’re designing it to be thrown in pockets and bags back and forth, a 1.5-3mm JST plug just isn’t going to hold up. Those things are flimsy, as are their pigtails and such.

Oh. Understand. I made that cause I was sick of losing my xt30 to 5.5mm

I wouldn’t ship with that.

I just have an aversion to using a 60 and connector. But I can change :wink:

I say just use a 5.5x2.1 barrel as the output (the female side, not male). Some powerbanks uses that as the 12v out plug and its easy to find 5.5x2.1 male to anything cables.

I understand that charging a Li-ion battery requires CC-CV charging method. Is this supported?

This is an awesome little charger, solid work and form factor.

Imo Gallium Nitride chargers are the next step in slimming down power bricks. They’re starting to hit the markets already and are hecka promising for a smaller portable charger. Unfortunately they’ll be stupidly expensive for a bit.

I was actually thinking it was the magnetic charging that macbooks have it is super cool and eliminates a port for water and dust to get in.

Why would anyone want to use that. Adds unnecessary parts to the BOM

This is really cool, just looked and there a bunch of PD triggers and a few lower voltage step up that are really compact, for my 6S ebike battery it would be perfect, well, apart from the fact that I have nothing that uses USB C :upside_down_face:

this is bad ass, i’d buy one.

Yeah it definitely does. And I doubt this board supports that, but maybe it does.

Something like this would work though.
Edit: Nvm, it won’t.

I would. Great concept!

One because it is a true macbook charger that way. If it has a plug it isnt a macbook charger but also it would remove an hole for water to get into the electronics.

6s could be made very very small. That’s super easy

Problem with those boosters-. They need a current limiting device after the USBc trigger, and before the booster, or the MacBook charger detects a short. It’s similar to a soft start .

I have about 20 different boost convertors off the shelf. Only a few have inrush current limiting so the caps don’t pull 30 amps when plugged into power in .05 ms
