    Help! Wiring of electric hub?

    Ok so a totall newbie to brushless motors. The hub has to go thru a motor controller , the three phases connecting to the same colour phase connections (in most cases). Battery power is supplied to the motor controller and not direct to the motor. The hub is unsensored so means it's operation...

    Need help arranging 13s7p 52v battery pack into battery case I've bought.

    Spend more time researching and understanding battery configurations, have a look on endless sphere battery tech sub forum for some good info.

    Need help arranging 13s7p 52v battery pack into battery case I've bought.

    You need knowledge to spot weld parallel and series grouping of cells, tbh if you are asking how to configure such a battery build one is best not to start at all. As it is you have displayed lack of knowldege or understanding. 13s is 48v yet you have said 52v !!! 52v is 14 in series.

    Help! Wiring of electric hub?

    The hub is an older style brushless hub, it is an unsensored hub. The three phase are std and if the motor runs roughly or backwards one simply swaps the wire sequence if colour to colour sequencing doesn't work.

    In southern europe it pays to have solar where the sun shines more. The difference living at 38 degress longitude compared with 51 degrees for the UK.

    Why car drivers DO NOT see cyclists

    From last nights program 25% of drivers deliberately close pass cyclists, an admission of dangerous driving as it is premeditated.

    Investigating Lithium battery generators

    Battery storage needs to be huge for any winter use. It is handy from spring to Autumn as the sun would replenish them during the day with good sun for off grid, following the night time usage. LFP 24v x 280ah is 7.168 kwh in my area with a near 2kw array for my spilt E/W azimuth the battery...

    Investigating Lithium battery generators

    One needs to work out the kwh one use per month or as a daily amount for the year. Over the last couple of years my usage has been approx. 6.8kwh per day for electric use, so an average per month requires approx. 204kwh. I have been more wary of prices and cost of energy and last month...

    Investigating Lithium battery generators

    As an example where I live South facing isn't possible but if it were I would get the following results. The first figures being 35 degree angle at 180 facing and the second figures vertical/90 degree angle both using 1.2kw array as an example: Jan 40/44 kwh. Feb 50/47 kwh. Mar 80/61 kwh...

    Why car drivers DO NOT see cyclists

    What a drive rshould do and will or does do is far form what actually happens. As the latest panarama report goes 1/3 of drivers simply don't give a s**t about cyclists. As I have told the wife, if I'm severely injured or killed by a vehicle she makes sure she sues the ass off the offender and...

    Help! help disassembling UPP EBIKE BATTERY !!

    Fire is unlikely dismantling unless one was really silly and used a metal tool and dropped it across the battery shorting cells out . For a fire it needs something more dramatic to occur usually a charge or discharge fault or major impact. I have deliberately punctured old cells and not seen...

    I shall watch as I also saw the BBC news item, of interest was one of the last clips where a car didn't stop at roundabout. Said car took out the cyclist but from the clip although the car should have given way to cyclist from the right, the cyclist did him self few favours by what I saw...

    Both will be 2 wire generic type, as log as one wires the polarity correct then simply change the mount rail over as already mentioned.

    Battery Unsused for 7 months. Still Safe?

    The main thing is if not using said battery for a while, try and leave it at approx 60 - 80% charged.

    Investigating Lithium battery generators

    A few simple numbers. My current price for elec is 0.35314p per kwh. A 1600watt pv array supposedly will producefor my flat roof 1321kwh of energy. Using those figures would equate to £466.47 in energy cost for electricity and say for a 3k outlay one would break even in 6.5 years. Come April...
