John Eucist Posted September 2, 2015 Share Posted September 2, 2015 Just bought another mten2. Looks like Gotway finally has a fan-less charger. Link to comment Share on other sites More sharing options...

Villac Posted December 4, 2015 Share Posted December 4, 2015 It is the one I received with a new model in OCT 2015. I don't know where to purchase just the charger. Consider contacting Gotway or the nearest merchant via the gotway site: http://www.kebye.com/ Link to comment Share on other sites More sharing options...

I ordered this one when I thought I broke my original charger but in fact I destroyed only my Charge Doctor. http://www.aliexpress.com/item/2A-67-2V-charger-for-16S-lithium-battery-pack-67-2V-Electric-unicycle-charger-recharger-aviation/32475704873.html Link to comment Share on other sites More sharing options...

They seem to be good quality, but be aware they seem more than twice as heavy as the ones with the fans. I suspect they have a much bigger heat sink in them! I use my generic wheel charger when I travel because it's a lot lighter to carry in the backpack. In any case I highly recommend having two chargers because they're not expensive and if you have a problem charging it really helps with troubleshooting.

sbouju Posted December 7, 2015 Share Posted December 7, 2015 Anybody using two of those 2A changer in order to have a fanless 4A charger, with just the help of a right "Y" GX16 adapter...? I have detroyed too my ChargeDoctor, at the exact time when I connected it to my wheel, and this, while CD was already connected to the charger and the charger not connected to the AC outlet... I guess that this is in rapport with the fact my wheel (a Gotway) can send its current to CD, a thing that a KingSong (for example) is not able to do.

I made several "Y" adapters for my friends as well who also have Gotway MSuper2. The suggested way is to plug both chargers to the main socket first, then the adapter, last to connect to the wheel.

Call me stupid, but I still don't know if there's any "intelligence" in these chargers... or is it all handled by the BMS? From the little I can tell from that picture, there's just transformer coils and ac/dc rectifying with some filter capacitors to keep the ripple voltages in check (and some further coils to bring the voltage down/RL-filtering)? But I'm an amateur when it comes to electronics Is there some kind of overcurrent protection for example? Link to comment Share on other sites More sharing options...

But I'm an amateur when it comes to electronics Is there some kind of overcurrent protection for example? 1. There is not much intelligence in these chargers as they are only CV-CC, two-stagger, with no low current cutoff. Because of the CC, the current will be limited to 2A even shorted theoretically(but I did not test this. The min. voltage I tested was 50V and it still gives 2A) 2. There are other components on the back of the board. Link to comment Share on other sites More sharing options...

I suppose the current just drops to near 0A when there is no voltage difference between the pack and the charger? It would explain why those hoverboards without BMS burn so often.
