    I wonder why these one-way sprag bearings/freewheels break? Is is perhaps because we put more battery power through them and then add our own power, particularly when we move away from an almost stopped position? Too much sudden torque and the weakest thing goes - at the point where the metal...

    Lithium Battery Pack - Build or Buy?

    Hi You may have decided on the laptop battery route already. I have had a good experience with using Headways (LiFePO4 cylindrical) bought from Eclipsebikes in the UK. Reasonable price, some warranty. Heavy for Lithium but robust and easily mendable packs. Easy to put together (no welding) with...

    Great Tommes, thanks for your trouble. This is the part I'm looking for in Europe. It fractured too when the bearing broke. I'd post in the German forum but I'm not as well educated as you guys and don't speak other languages so well!

    Hi Tommes, Thanks. The helical gear I was talking about is this one with the bearing (I can get) in the middle: It's the first gear you get to when dismantling the gearbox and the thing that broke first too - so presumably it's the weakest link. As I say I got a couple of spares from CATIC (and...

    Tommes - that's a useful German thread you linked to. I have the older style gearbox and have put a granny chainwheel 24t on it but haven't got round to fitting a front derailleur so I have to stop and manually change the chain over - not a major pain as I have a small 34t main chainwheel which...

    Combining 2 batterie packs with sep. BMS in parallel

    I don't know if that diode you described would be meaty enough as I'm no expert! I would ensure that it was a higher rating. They're only a few £s. Well I take the advice of EEs - there's a guy called Tiberius on here that seems to know what he's talking about and I quote one of his posts...

    Combining 2 batterie packs with sep. BMS in parallel

    jk1-all I know is I researched paralleling 2 batts here and Pedelecs UK forum and this seemed the easiest and safest solution. There is no other parallel wiring to do - just attach each live batt output to one or other of the Schottky (causes less V drop than normal diodes) diode outer legs...

    Combining 2 batterie packs with sep. BMS in parallel

    Yes 2 batts in parallel double the AH and halve the draw from each batt. Less strain on each batt. It's probably best to use a double Schottky diode to protect the BMS's from reverse surge current. See http://www.maplin.co.uk/30a-schottky-barrier-rectifiers-46429. It's about 3-4cm long. Attach...

    I've got an older version of the Tonaro gear box. Put about 900W max through it but at lower gears/higher RPMs. Gets me up some very steep places offroad without pedalling. Had to replace one bearing/helical gear but I think that was not strain but collision damage. Got that (2) direct from Javy...

    Tonaro bighit clone - battery question

    Yes always better to keep the battery as fully charged as poss - unless storing for months - then 50% or so and topped up reg as BMS draws a small current (check this...). Just adding a small amount of solder to the thick, U-shaped, bare metal wire (easily accessible by taking the 'wireless'...

    Tonaro bighit clone - battery question

    Hi Anders Yes it might be the battery is a bit depleted - was it sold to you as brand new or had it been used as a demo bike previously? Batts degrade apparently from the first day they are used. They also don't perform as well in cold weather - don't know how far North you are?! I found my...

    Busted Tonaro/iGO type gear box

    Hi Just got my bike almost where I wanted it then in a mad fit took it somewhere good.... and trashed it! Crank or something hit a rock as I was accelerating - nasty snapping noise and no power to the pedals. Opened it up later and found cracked final bearing and also cracked final 'helical gear...

    Fet current sharing? Noob alert..

    Cheers Boost. I've got bogged down in calcs for heat transfer and too many unknowns but that's all useful info. Maybe this thread ought to be included in the wiki for noobs?

    Fet current sharing? Noob alert..

    Thanks for that encouragement and info! Haha I think I may have given the false impression of more understanding than I actually have... it's some of the basic things I don't have a grasp of - on the level of 'that's not a cup holder, sir, it's for the DVDRom drive'. I was thinking that I would...

    Fet current sharing? Noob alert..

    Hi I've read around a lot but get confused by differing answers and general ignorance on my part... I just want to guestimate how many A's I can mod my tiny 6 Fet or a 9 fet controller shunt to before blowing a fet - as it can be an expensive experment - so looking for very rough 'rule of...

    RMartin R10 running at 1800Watts through Nuvinci N360

    Ta for the pics and the help. Yep, looks nothing like mine! Not worrying, just want to know what to do to maintain things properly really... prevention better than cure. Health means I just can't afford the bike to break down any distance from the car. Got the controller working fully now and so...

    Help with wiring in new no-name controller please!

    OK - reversed leads in new PAS connector and then re-flipped PAS disc and it worked. So disc did have to be reversed to work with different controller but so did the leads - had to get the right combo. Now trying to calc how much current I can put thro this controller without frying components...

    Help with wiring in new no-name controller please!

    Thanks d8veh. Tried what you suggested but still no go. Disc is on the non-chainwheel side. Was working with the old controller. Hmmm.. Was concerned re which PAS wire was which on the new controller. Presumably the 4.9V is 5V and the 4.2V the signal? Tried swapping in plug - made no...

    Help with wiring in new no-name controller please!

    OK got the new controller working - sort of! I decided to just disconnect and ignore the 3-way that included the orange wire from the stock wiring loom - so bypassing the power switch etc. Everything seems to work but the PAS... Throttle OK. Brakes cut throttle. Runs with/without Halls...

    Help with wiring in new no-name controller please!

    OK guys think I've got the idea now. Just awaiting a 6-way from ebay to wire the new controller to fit the stock wiring so I can use it. Thanks again for chipping in.

    Help with wiring in new no-name controller please!

    Cheers guys - always count on you two! OK bit confused re Orange wire which is on the old controller - so are you are saying it does carry a 36V supply back to the controller and wakes it up? So does it have to be connected or can I just ignore that whole 3-way and attach thin yellow wire to...

    Tornaro Bighit Review and Upgrade

    Wiring diagrams anybody? You can see my struggles with wiring in a new controller to the Tonaro here http://endless-sphere.com/forums/viewtopic.php?f=2&t=40635. I've attached the one for the UK Tonaro which is almost identical to mine. I think I've identified most wires but I'm stumped as to...

    Help with wiring in new no-name controller please!

    Got a Tonaro stock controller - see attached wiring diagram. Want to sub it for a no-name Chinese 36/48V with/without sensor BL one. Only got pics showing role of each plug for that - see attached also. Tried to plug the new one a via soldered on Deans into a 36V battery. Big spark first time...

    RMartin R10 running at 1800Watts through Nuvinci N360

    Yeah Greg, yours and gorach's crank/freewheel and your gearbox construction/disassembly seem way different to mine...! Mine just 'falls out' after removing the crank and some screws! I also couldn't see a pin holding the motor pinion so another difference. I think I must've got an old model...

    Tornaro Bighit Review and Upgrade

    Well, my Tonaro moves off and drives on throttle alone without pedalling, with the front chainwheel freewheeling. Does yours go faster than about 4 mph on throttle alone? If not it may be a 'walk with the bike' kind of throttle? So are you saying you have no freewheel ability on the front? If...
