Popular Post Garrie Lim Posted September 4, 2019 Popular Post Share Posted September 4, 2019 (edited) Hey guys, as you know, I made some adaptors to use my current escooter chargers to my new wheels. So basically I just need one charger and different adaptors to fit into the different ports/connectors of my wheels. However there seems to be this void when it comes to knowing the polarity of certain wheels. So allow me to reveal the polarity to you if any of you ever choose to do a DIY project. I don’t own all the wheels in existence but what I’m sharing here will be the ones I have come across Gotway(MSX 84v, Nikola 84V, Tesla) GX16-4 1:Positive 2: Negative Gotway(MSX 100V, Nikola 100V) GX16-5 1: Positive 5: Negative Kingsong(KS16X, KS18L, KS18XL) Inmotion V5/10F(??? Not sure I dun own inmotion wheels?) Lenovo-type/C36 connector Inner contact: Negative Outer contact: Positive Hope this info helps you out for your DIY projects.

Lenovo-type/C36 connector Inner contact: Negative Outer contact: Positive I can contribute a little regarding this -- the Lenovo-type connector has 3 connection points, not 2 (you missed the pin), and the V5 has it wired slightly different from the KS18L: KS18L charger Outer contact: positive Inner contact: negative Centre Pin: disconnected KS18L wheel Outer contact: positive Inner contact: negative Centre Pin: positive V5 charger and wheel: Outer contact: disconnected Inner contact: negative Centre Pin: positive This has two important implications: The KS18L can use the V5 charger, but the V5 cannot use the KS18L charger. If you wire up a female C36 connector in the same way as the KS18L wheel, you can accept both V5 and KS18L chargers. Making a charge adapter for the Inmotion V5 is much more difficult than the KS18L because male plugs don't seem to be available on their own, and the off-the-shelf barrel-to-C36 plugs leave the centre pin disconnected as well. Additionally, the Inmotion V8 uses a GX12-3 connector, but the Solowheel equivalent (Glide 3?) uses a GX12-4 connector (those jackasses just had to make it incompatible). I don't recall what the pinout was, though. Edited September 4, 2019 by hyperair 6 Quote Link to comment Share on other sites More sharing options...

If you are not careful you can short circuit your battery. Ah sorry, @hyperair gave a more detailed explanation Quote Link to comment Share on other sites More sharing options...

Jean eRide.ie Community Posted October 13, 2019 Share Posted October 13, 2019 (edited) I asked a chargers supplier on Aliexpress about the limits current for GX16-5, and I was told 100.8v 10A is close to the limit and GX16-5 1+ 5- (2 pins connected) is not recommended. They suggest using 4 pins connected, like 1+ 2+ 4- 5-. Is this something already supported on the Gotway Monster v3 100V? Or should be modified? As per Gotway, the v3 can support up to 20A, meaning the GX16-5 male port can stand that too? Also eWheels suggests not to go over 8-10A just in case a battery ever fails, no mention of the connector limits.

Jean eRide.ie Community Posted October 13, 2019 Share Posted October 13, 2019 (edited) So Gotway improved the Monster v3 to have thick gauges to support 20A, but didn't use 4 pins instead of only 2 on the 5pin connector, making it stand 5-6A maximum, it makes no sense Edited October 13, 2019 by Jean Dublin 1 Quote Link to comment Share on other sites More sharing options...
Jean eRide.ie Community Posted October 16, 2019 Share Posted October 16, 2019 @Jason McNeil can you please confirm the above? I see you say its not recommended to charge the Monster v3 with more than 8-10A, but it seems like the connector can only stand 5-6A maximum?

Jean eRide.ie Community Posted October 17, 2019 Share Posted October 17, 2019 Someone from Spain told me the limit is 5A per Pin, so if using 2 pins (1+ 5-) the limit is 10A. I've been trying to find that confirmation online hard to find... But found an eBay seller who said that. But then discussing with the Chinese charger supplier, he insists that the limit is per 2 pins (1 pin positive, 1 pin negative), so 2 pins used (current setup) limit is 5A, and if I modify the EUC plug inside to be 1+,2+,3-,4- it would be 10A limit... Any expert in here who knows? Thanks. Ebay listing I mentioned: Quote Link to comment Share on other sites More sharing options...
Hansolo Posted October 17, 2019 Share Posted October 17, 2019 heuuuu, if you want decrease the current by pin, you must use 4 pins, 2 for + and 2 for -. but watch out for short circuits if the socket is turned upside down by forcing...

Thanks. Yes, makes sense. But, with the current connector setup, 2 pins used 1+ 5-, is the limit 5A or 10A? @Seba you probably know?

First, I strongly recommend not to exceed 10 A of charging current even in case of Monster V3 100 V. It's because you can't be sure how well current will balance between each pack inside EUC. I also suggest to use pinout as suggested by the seller: 1+2 for positive and 4+5 for negative. Even if single pin could handle 10 A for some time, every connection/disconnection will cause contacts to degrade. This will raise their resistance, causing more and more heat to build up. In higher temperature contact corrosion and oxidation will be faster, thus expediting whole degradation. 2 Quote Link to comment Share on other sites More sharing options...

I don't want to modify the Google Monster connector to use 4 pins, I will leave it with the original 1+ 5- setup. So, 100v 6A (c600c 750w) would then be OK for the GX16-5? That seems to be the most powerful charger I could find under 10A which wasn't adjustable and doesn't look massive. Quote Link to comment Share on other sites More sharing options...

esaj Posted October 18, 2019 Share Posted October 18, 2019 (edited) @hobby16 has a list of connectors and their polarities in his site ( http://hobby16.neowp.fr/2016/11/20/charger-customization/ ), I guess it's ok to copy-paste them here. Do note that these are from several years ago, and newer wheels might have different pin-out or connectors, so check beforehand to be sure: Most frequently found connectors e-Wheel Socket Wiring Voltage Topo* Remark Most e-wheels GX16-3 1: V+ ; 3: 0V 67.2V 16S connector for Solowheel, Airwheel, Gotway, Firewheel, King Song… Gotway MSuper3 84V/1600Wh GX16-4 1: V+ ; 2: 0V 84V 20S other MSuper3 with battery <1600Wh have GX16-3 connectors IPS (Holtz, Zero…) GX16-4 2: V+ ; 4: 0V 67.2V 16S warning, same connector as above but different wiring!

Planemo Posted October 23, 2019 Share Posted October 23, 2019 I know this thread refers to the Monster (with 5 pins) but just to clarify, we are saying that its OK to run 6A into 2 pins only (for example a stock 84v MSX)? Quote Link to comment Share on other sites More sharing options...

Planemo Posted October 24, 2019 Share Posted October 24, 2019 Thanks. I will keep an eye on it (or rather, laser temp probe) for the first couple of charges just to be sure. I think it will be ok, given 5 amp is officially ok so 6 shouldnt be horrendous. 1 Quote Link to comment Share on other sites More sharing options...
Jean eRide.ie Community Posted March 22, 2020 Share Posted March 22, 2020 It turns out that Monster v3 now use 4 pins direct from factory. So 10A is OK without modification. 1 Quote Link to comment Share on other sites More sharing options...
