    Old ebike, new controller and throttle

    Hi. I have an old ebike, basic frame from 2000, modified for lipos and brushless about 15 years ago. The controller broke recently so I replaced it with a cheap one on ebay with many more wires than I needed. I also bought a new throttle at the same time, a basic 3 wire one. I have connected...

    Power analyser over 60V?

    I have a couple of cheap HK power analysers that I use for charging and on the bike to monitor voltage and battery capacity. They do a reasonable job with my 12S setup. I'm thinking of upping the voltage of my pack by adding 3S giving me a fully charged pack of 63v. The power analyser I've got...

    Cheap 72V charger

    Sorry if this has been asked many times before. I've spent a while looking but failed. This continues from my thread over on the ebike general discussion http://endless-sphere.com/forums/viewtopic.php?f=3&t=44743 I have a 8 lipos configured in a 12S 4P2S setup which I am bulk charging with a...

    Possibility of putting 66V through an MXUS DD rear hub?

    Hello all. I have one of these: from cellman. It's a 500W MXUS Direct Drive hub (XF40 I think). It's ace. Top speed is 25mph on the flat with 48V of lipos powering it. Inevitably I want a few more mph in my pocket, for 'occasional use' on 'safe' roads. Only 2 - 3 more mph you understand ;-)...

    Meanwell clone fail...?

    So I got my new Meanwell clone from eBay. http://www.ebay.co.uk/itm/170661884432 I did the current limiting mod, set it charging my lipos and turned the screw on the pot until the current hit about 6A. I hadn't yet done the 'always on' fan mod. Half hour later the green light went off on the...

    SLA charger on Lipos

    My modified 48V PSU failed just now. I think it's a 'Meanwell' clone. My friend modified it to output 50V. Anyway, it had been working happily for a few months but (despite reasonable cushioning, so I thought), did not like being transported to and from work on my panniers and the coil bit...

    Fitting a CellMan DD hub to 10yo 'Strong' ebike....

    .... or confessions of an impatient newbie bodger. I have this: which I'm told is Chinese in origin and they were imported into Canada under the name 'Strong GT', or Strong GT-S210. I bought mine from a little shop in London 10 years ago and they called it a 'Tornado'. Just recently I've...

    Connecting lipos - noob alert

    I'm trying to think through how to connect 4 lipos together in series and parallel. Here is my rough diagram so far: I'm thinking of the XT60 series and parallel connectors because I've seen them on the HK website and it would save making any (or paying someone to make some). At the moment I...

    HK site refers to a 'charge plug'. Is it a charge plug?

    Hi. I am a Lipo noob, although have used them for my small r/c helicopters. When I charge my small 7.4V Lipos for the helis I plug in the 2s balance charge lead into the charger and it charges the battery until auto cutoff. I assumed this was the same for larger Lipos that I'm thinking of using...

    Noob needs help putting rear wheel back on.

    I am revealing the depth of my ignorance here, but I can't work out the proper order that things should go on the rear axle. Here is what I've decided is probably right: But I'm not sure. Maybe the washer goes on the other side of the fork. Maybe the ring bolt thing does too. I know it all looks...

    Please help me identify my nuts!

    Hi. I've removed 2 nuts from my rear axle. They need an 18mm spanner on them. They are 1cm in height (when you lay them flat). I want to buy a couple of replacements (I mangled one of them a bit). But I can't find any online and don't really know what to look for. i.e. what search terms to...

    Please help me with my brushed motor!

    I had a short on the wires going into my brushed motor. I'm trying to get further back on the wires so I can rewire the connections. I've taken the wheel off and the disc pad but don't know what to do next. I'm a bit of a beginner with bikes and may need to buy a tool or two. Hopefully someone...

    10 year old lead acid 36V e-bike needing an upgrade!

    Hello everyone. 1st post from me. Thank you in advance and all that :-) I have a 10 year old electric bike. It's similar to this one: http://www.ourcar.co.uk/ECOtornado.htm but runs on a 36V lead acid battery. It has a brushed rear hub motor and is limited to 15 mph (due to UK law). I had a go...
