felixx Posted January 7, 2017 Share Posted January 7, 2017 So I'm picking up an electric scooter (like a nifty 50 but electric. ) It was free but isn't charging Anyone know much about these? Quote Link to comment Share on other sites More sharing options...
Willdat? Posted January 7, 2017 Share Posted January 7, 2017 Not specifically about electric scooters but I'll probably have some ideas - cheap option is that charger is poked - more expensive is that batteries are not happy. Post some photos up once it shows up and I'll throw some ideas at you for fault finding. 1 Quote Link to comment Share on other sites More sharing options...
8ball Posted January 8, 2017 Share Posted January 8, 2017 +1 for the batteries Quote Link to comment Share on other sites More sharing options...
UTERUS Posted January 8, 2017 Share Posted January 8, 2017 I can also offer guidance on what to probe when you get it. Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted January 8, 2017 Share Posted January 8, 2017 Increase the power supply and it will go hard for what it is. My guess is the batteries will be fucked. Check to see if the charger is supplying voltage to the battery Then whack two 18v batteries in it in series and do hunnitz. 1 Quote Link to comment Share on other sites More sharing options...
8ball Posted January 8, 2017 Share Posted January 8, 2017 Mate had one (was ild looked agricultural as f#ck lol) We ripped it and fitted 6 Milwaukee batteries. And a new motor setup after we fried the original lol. If you nailed it straight off you almost guaranteed to find yourself sitting on ya arse staring at the scoots about 10m away lol. That thing was scary as f#ck. Probably also due to the severe lack of brakingand shite handling lol Quote Link to comment Share on other sites More sharing options...
felixx Posted January 8, 2017 Author Share Posted January 8, 2017 4x 12v batterys 2 Had terminals that corroded that they broke off. They were lead acid batteries. I will look into some power tool batteries or similar Quote Link to comment Share on other sites More sharing options...
8ball Posted January 8, 2017 Share Posted January 8, 2017 See if you can use the power tool (recreate/copy) the quick release clip i setup for quick easy battery swaps. And get the biggest amp hour ones you can get. (Ie 6.0 or 5.0ah) Quote Link to comment Share on other sites More sharing options...
Muncie Posted January 8, 2017 Share Posted January 8, 2017 I have a speed controller and hand control here leftover from my electric to petrol conversion on a stand up scooter a few spare 12v batteries too. Will watch to see what you find is poked. Quote Link to comment Share on other sites More sharing options...

The cost of replacements is about $120 each so 500 bucks is a bit mad. Those only gave it 10 km or so range. Hmmm Quote Link to comment Share on other sites More sharing options...
Willdat? Posted January 8, 2017 Share Posted January 8, 2017 Do you know what wattage the motor is rated at? You may find it's only one of the batteries that is fried/dead/dry. Pull the batteries out and have a go at charging them individually with a car charger. Is it a hub motor or separate chain drive unit?

8ball Posted January 8, 2017 Share Posted January 8, 2017 Yeah this was too. We ran them in parrallel and series so it gave extra voltage yet also larger capacity. If you're just after a commute (then a different setup may be required.) We had this setup for a hoot. Probably ran 10-15mins. But most of it was flat out launches/drags and the odd burnout lol. (Elec burnouts are weird) You may want a few SLA batteries to keep it cheap and give you distance? You may also find the electronics (speed controlller etc) as the juice killer. A cheap inefficient motor and speed controller will not only give poor performance but also limit its distance of travel. You may find swapping the motor etc for something better may enable you to run "less" battery for the same results or better. Quote Link to comment Share on other sites More sharing options...
felixx Posted January 8, 2017 Author Share Posted January 8, 2017 They were set up in series. 2 of the 4 were that corroded that the terminals actually snapped off. . I will try the rejuv function on my charger on the other 2 It is a hub motor. I will get more details when I get time later in the week Quote Link to comment Share on other sites More sharing options...
h4nd Posted January 14, 2017 Share Posted January 14, 2017 250w solar panel / roof / sunshade? Unlimited range... May even be quicker than with 40kg of batteries. 1 Quote Link to comment Share on other sites More sharing options...

felixx Posted January 18, 2017 Author Share Posted January 18, 2017 Lol genius Does anyone have a 48v battery in canterbury I could borrow/test this? Quote Link to comment Share on other sites More sharing options...
h4nd Posted January 18, 2017 Share Posted January 18, 2017 Yes, actually; though it has a horrifying short circuit capability (like 20 - 50kA). I have a more benign PSU I can drop in instead. Quote Link to comment Share on other sites More sharing options...
