dubgee2002 Posted June 23, 2015 Share Posted June 23, 2015 I finally got my hands on a TG-M3. After unpacking, and getting everything set up, I noticed that the charger is not charging the EU. I charged it for over 2 hrs, and still only 1 red light is on. I couldn't wait so I tried to hop on with not much success. It was only about 5 min.My question is, is it easier to ride with more power/full battery, or does it not matter much? Link to comment Share on other sites More sharing options...
KaleOsaurusRex Posted June 23, 2015 Share Posted June 23, 2015 It matters more than you might realize, especially with the lowest priced ones right now. When the battery is low, there's a chance it might drop you at random. Try attaching the charger to the unicycle before plugging it in, then look for the light on the charger to turn on red. I recommend charging before every ride on beginner micro unicycles with small batteries like that one. This is based on research and experience with TG T3 and Airwheel X8.

Gimlet Posted June 23, 2015 Share Posted June 23, 2015 Wheels use a lot of their power to keep you balanced forward and back.Low battery equals low power equals low balancing ability.Get the charger replace asap. and get it fully charged. Link to comment Share on other sites More sharing options...
dubgee2002 Posted June 24, 2015 Author Share Posted June 24, 2015 Thanks for the input.Urrggh, so frustrating. Im raring to go (ie: fall) and learn how to ride. Link to comment Share on other sites More sharing options...
Gimlet Posted June 24, 2015 Share Posted June 24, 2015 There are normally a few euc chargers on ebay. You may be able to get one more quickly off there if you can find a local seller. They're not very expensive.It's always useful to have a spare when you do sort out a replacement from your original supplyer as you can then either carry one with you or leave it at your most regular long distance destination to charge up for the return.

dubgee2002 Posted June 25, 2015 Author Share Posted June 25, 2015 I got a reply from the customer service at banggood, and they told me that it looks like a battery problem, not the charger.Anyhow, they have agreed to send me a new battery. Is this difficult to replace on my own? Don't want to mess around taking apart a brand new EU, especially when I don't know how to do it.Thanks, Link to comment Share on other sites More sharing options...
hobby16 Posted June 25, 2015 Share Posted June 25, 2015 Anyhow, they have agreed to send me a new battery. Is this difficult to replace on my own? Don't want to mess around taking apart a brand new EU, especially when I don't know how to do it.With TG wheels, it's very easy, see here : http://trottinetteselectriques.heberg-forum.fr/sutra9032_tg.html#9032The battery is on the side opposite of the control panel.

dubgee2002 Posted June 26, 2015 Author Share Posted June 26, 2015 Thanks hobby16. The website doesn't work, but i'll figure it out. Good to know at least where the batt is. Link to comment Share on other sites More sharing options...
Gimlet Posted June 26, 2015 Share Posted June 26, 2015 It might be worth your while to get a cheap multi meter and poke the probes up the holes on the charger plug just to check if it's providing the 67v that it should be.If it isn't I would still allow banggood to send a new battery as they are much more expensive than chargers, like I wrote before, you can pick up a charger from eBay quite cheaply.

Lorents Posted June 26, 2015 Share Posted June 26, 2015 Bangood also sells a great charger at a good price:http://www.banggood.com/Electric-Unicycle-Charger-AC-to-DC-Power-Supply-p-966060.htmlAlways a good idea to have a spare one. Measured mine with the charge doctor and it charges at 1.96A and evens out at 67.3V Link to comment Share on other sites More sharing options...
dubgee2002 Posted July 10, 2015 Author Share Posted July 10, 2015 I got my spare charger, but had a question. Is it supposed to be green when I plug it in, or red? I have two chargers, and they're both green when I plug them in. Fan does not run at all either. Banggood is cheap, but man about about 2-3 weeks to ship.

esaj Posted July 10, 2015 Share Posted July 10, 2015 I got my spare charger, but had a question. Is it supposed to be green when I plug it in, or red? I have two chargers, and they're both green when I plug them in. Fan does not run at all either. Banggood is cheap, but man about about 2-3 weeks to ship. At least both the chargers I have (one for the generic and one for Firewheel) show red light when they are charging. The generic charger has a fan which runs always when it's charging, the Firewheel charger is fanless. Sounds like the battery (or BMS) is dead or there's a connection issue, see if this gives you any clues:http://forum.electricunicycle.org/topic/294-newbies-first-day-on-wheel/?do=findComment&comment=3300One of the wires had came off from the charger port, but it could also happen in the connector between the port and the battery, or somewhere else.

MetricUSA Posted July 11, 2015 Share Posted July 11, 2015 Good gully, bad battery, don't throw away battery! If you find what's wrong with it, you maybe are to install both if you have room, if not, breaking down that pack and use the 18650 batteries for other uses...as only one cell can ruin a packpack, others good, and said dam expensive...

dubgee2002 Posted July 19, 2015 Author Share Posted July 19, 2015 I finally received my battery in the mail...it doesn't fit. Picture 1 is the battery attachments for the EU. Picture 2 is what came with the battery. This whole process has taken about 1 month,and I still haven't even been able to try the dang thing out. Its very frustrating to walk by my EU everyday, and not be able to ride it because they shipped a faulty battery. Im worried getting another battery that fits will take another 2-3 weeks or so just be be resolved. Is it simple/possible to just swap out the connector that doesn't fit to one that fits? I would guess a hardware store would have the parts. Link to comment Share on other sites More sharing options...
Gimlet Posted July 19, 2015 Share Posted July 19, 2015 The yellow connector is the one which supplies power to the wheel and is correct the other connector is for charging and you can swap out the connector from your other battery.If you don't have a soldering iron the easy bodgers way to do it is to cut the wires an inch or so from the fitting and reconnect with a small connection block which you can get from any electrical or diy store.

esaj Posted July 19, 2015 Share Posted July 19, 2015 Pretty much any connector should do, as long as it can handle the current (charging side current is much lower than the power-wires side) and you don't go shorting it or connect the wires wrong way around. If using screw terminals (which I think Gimlet means with "small connection block"), better put some electrical insulation tape around them, so the bare metal parts cannot go shorting anything.About the connectors, the yellow connector is called XT60 (can handle 60 Amps), and those are available from pretty much any RC-store, as they're very common in radio-controlled cars/boats/helicopters/planes/whatever: https://www.sparkfun.com/products/10474The white one looks like MAYBE a female Tamiya-connector: https://en.wikipedia.org/wiki/Tamiya_connectorThe red one in the lower picture looks like female Deans-connector: http://www.nghobbies.com/cart/index.php?main_page=product_info&products_id=543You can probably get any of these from a local RC/hobby-store for a few bucks/euros.

Tilmann Posted July 19, 2015 Share Posted July 19, 2015 With "small connection block" I believe @Gimlet is referring to this sophisticated device from the early ages of electrical engineering (source: wikipedia DE). If there is enough room, it should do the trick. Link to comment Share on other sites More sharing options...
Gimlet Posted July 19, 2015 Share Posted July 19, 2015 That's the ones! Although a small 5amp one would probably fit in more easily and be more than adequate. Link to comment Share on other sites More sharing options...
devvdude Posted July 31, 2015 Share Posted July 31, 2015 I too have the same issue with the cheap chinese EU.They sent me a charger that they claimed didn't work, so they sent me another charger. When i turn the EU on it moves forward, backward, then all top lights light up red and it beeps. They claimed next it was the battery, but i asked for a refund and they gave it to me (plus let me keep the EU) So if you figure out what is wrong with yours please let me know so that i may be able to fix mine.
