    Change single power level to low/med/high power levels???

    Your motor is also 200w whereas most are 250w , more torque and better hill climbing

    Change single power level to low/med/high power levels???

    With the best will in the world the Evora is a very low spec cheap bike That small 6.6ah battery won't last you very long either What I mean to say is that you are probably better off putting up with the bike you have and, when the battery or something else packs up, then spend the money and...

    Hub motor making horrendous noise!

    Thanks for offer of the bike for spares Kirstin S, but Brighton a little too far from Cornwall! Agreed. It would cost more in petrol or train fares just to come have a look !

    Synergie Mistral- Battery issue mainly

    Do you have a multi meter ? What does the pack read ? If you open it up you'll find 10 x 3.7v 10ah rectangular cells If any are reading 0 then it's game over - cannot revive them You can use a lipo charger to bring each cell back to 4.2v as long This is what I did - took hours . I was told...

    Synergie Mistral- Battery issue mainly

    Don't do that please ! I think you are referring to technique of passing a very high voltage , sometimes a welder, for a moment across the battery to revive them? That's for nicad batteries not lithium that you have. If nicads then can reinvigorate but lithium may set on fire/explode or at very...

    Indicators

    I have had shop bought and also built my own They work BUT they just don't seem as effective as hand signals My guess is that car drivers expect hand signals from cyclists. Lights on cycles are for being seen/ seeing by I did biuld some LEDs into some winter gloves to get best of both worlds...

    80% charge after short time with Lipos?

    Shambolic has a 48v battery. D8veh is quoting you the voltage for a more standard 36v You need to match your current charger

    80% charge after short time with Lipos?

    Good point ! Hadn't thought of that

    80% charge after short time with Lipos?

    Ahh it's nota efficiency thing it's more that the battery won't have 14ah of actually useable power. Once it gets down to about 3.2v per cell the BMS should shut it down Also I didn't bother with any tapering of charge as I can't guess what that might look like. And the taper wouldn't kick in...

    80% charge after short time with Lipos?

    Hmm doesn't sound like a lipo battery to me Sounds like a more standard ebike battery eg liMn It's a 13 cell series battery at 48v nominal. 54.6v is the charge voltage and pack voltage got off the charger A 1.8amp charger is pretty low powered/slow. Especially for a fairly big battery like...

    80% charge after short time with Lipos?

    The short answer is Yes to 80% faster than the last 20% But how fast depends on your chargers capability to pump electricity into your battery (ie what amp rating is it ?) And how much electricity your battery needs to be 80% full (ie what aH rating it is) If you have these figures you can...

    Discharge test

    Yes - exactly the same software and capabilities The only difference is the turnigy version is fan cooled and the IMAX is passive cooled by heat loss fins

    E-Bay Batterys

    Sorry if you consider this a thread hijack But... Can I ask what your booster is ? Lipo or a another type I ask as I use laptop batteries of various chemistries but not lipo I have a totally unsubstantiated feeling that the high c rating of lipo might hurt my main pack z- I think I read...

    Conversion kit poll

    You list is mostly motor manufacturers but kits often use same motor but a big difference in the rest (LCD vs basic led handlebar panel, waterproof wiring vs basic Chinese clips , quality rims vs basic, quality spokes vs Chinese cheese, torque vs rotation, mid vs hub etc) An wether they bought...

    Discharge test

    Just to confirm readings I repeated the test using one unit only Got exactly the same results (well within 1% tolerenace) So this does work
