    Difficulty in dismantling ebike front hub motor

    Yes-makes sense-I have bought these from BMS battery and they are not that expensive. Fright can be expensive

    Difficulty in dismantling ebike front hub motor

    Thanks for that comment Papa-appreciated. I bought 2 of these motors and unfortunately when dismantling I used screws that were too long and they went through the component and damaged the clutch ( on one of the motors) For other readers please use screws that go no deeper than the original...

    Difficulty in dismantling ebike front hub motor

    Thanks for that information-problem solved. I would never have thought that it came apart as a threaded component-in many ways a very cleverly put together piece of equipment. My reason for wanting to pull it apart was that occasionally when riding the bike the motor seemed to grab-making what...

    Difficulty in dismantling ebike front hub motor

    This motor (Pictured) is giving me a heap of trouble trying to get it apart. The supplier BMS Battery has not answered my email and I have not been able to locate parts diagram. Has someone successfuly taken one of these apart ModelQ100 350w Thanks Peter

    Does an MPPT solar controller have ripple in the output

    I have read LiFePo4 cells last longer if the charging current does not pulse ie the best charging current is a flat voltage rather than a pulsing current/voltage which may be better for lead acid batteries. Is there any truth to this and is there a better type of controller for these lithium...

    Battery charging

    I have a 24v 5A dc supply which I have linked to a buck converter. The output of the buck converter is set to 13.4v and then connected to a 12v lead acid battery reading 12v-so the battery is a little low on charge. An ammeter between the buck converter and the battery reads 0.15A however...

    Bigwei LIFEPO4 100Ah cells

    Does anyone have any experience with these cells? Available in Australia AT $A139 per cell-Chinese brand so perhaps not that good???

    Using a buck converter to make a battery charger

    I have a 24v dc power supply and have been attempting to make a battery charger for a12v lead acid battery using the buck converter pictured here. I find that the potentiometer for current adjustment has no effect and want to know just how fragile these devices are. It should be easy enough to...

    Looking for e bike enthusiast in Brisbane Qld

    I have been using ebikes for about 15 years and have replaced LiFePo4 cells in 36v packs and done other fairly simple fix up jobs such as replacing the bms. Now living in Brisbane after living in a provincial town in Qld (Maryborough) and hoping to meet up with like minded people who do some...

    10w solar panel connected to lead acid battery

    I have a question about whether a 10w solar panel left connected to a typical car battery-about the size of a Toyota Camry would prolong the life of the battery or actually cause harm by overcharging. That is connected without a solar regulator direct to the battery. The solar panel has an...

    Anderson plug irritation

    I am using 2 Anderson plugs as a substitute for main switch on my electric bike. When I go over a bump the bike sometimes loses power and pulling the plug out and re-inserting it fixes things until it happens again. Looking carefully at the plug I can see that the clip that sits under a lip on...

    12v Battery out of 18650 cells

    Thanks for those replies-appreciated However I have another question-I am making up a few simple projects and one of my concerns is that the Li ion cell becomes over discharged and damages a cell. Have looked on eBay and not found anything suitable so far. Would you need under voltage...

    12v Battery out of 18650 cells

    I want to make a small battery out of 18650 cells with 3 groups of 6 cells joined in parallel then the 3 groups joined in series to give the amount of power and voltage that I want. I have been charging individual 18650s with a TP4056 board and mobile phone charger for the power supply. Is...

    Electric bike has very stiff steering when in motion

    Took the headset apart to grease it-the lower bearing was caged and only bit of the cage left-bearing balls missing or chewed up. Surprising that it still turned. A new set of bearings cost $5. They probably won't have a long life as the places where the bearings seated are worn-but one big...

    Electric bike has very stiff steering when in motion

    Thank you for that information. I sprayed the headset bearings with WD40 and took the bike for a ride-very much improved so i upended it and soaked the bearings with engine oil-now really good. I realise that the oil is not a long term answer and the headset will have to be dismantled and the...
