    Battery pack cell balancing

    Yes, absolutely. As a pack ages, it will require more frequent balancing. A couple of days is likely somewhat overkill, but a long balance is never a bad thing for a pack.

    Battery pack cell balancing

    Okay.... A pack becomes unbalanced when the voltage of individual cells differ - The higher the difference, the greater the imbalance. BMS's use a series of resistors to bleed (lower) the voltage of the higher voltage cells in order to equalize the voltage of each cell in the pack. So...

    Battery pack cell balancing

    The main reason for this is because the bleed-down resistors on the BMS used to discharge the high cells are pretty weedy and can only do so at a trickle.

    DIY EBIKE

    For a low powered bike, a geared motor makes sense. Once you want to raise power into the multi kW range however, a direct drive is the only way to go if you require any kind of reliability.

    Brexit, for once some facts.

    +1 argumentum ad hominem - a logical fallacy in which an argument is rebutted by attacking the character, motive, or other attribute of the person making the argument, or persons associated with the argument, rather than attacking the substance of the argument itself.

    Brexit, for once some facts.

    This Spectator article is excellent - it addresses the point of sovereignty in a calm and well thought out way using only facts to back up the writers position rather than speculation or plain inaccuracies - 10/10 - if only there were more like this coming from both sides...

    The Best Mobile Telephone Ever Made for only £9.10

    I'm pretty sure you could still be traced through GSM cell tower triangulation, but only accurate to several hundred meters or so.

    What to do about the controller bag?

    So, these boxes won't fit anything bigger than a 6FET then?

    News - DfT: Pedal cycles converted to ‘twist and go’ exempt from type approval

    Technically you're rotating a magnetic field around a sensor - potentiometers are very rarely used for electronic control anymore.

    Brexit, for once some facts.

    I tend to steer clear of political discussion on this forum, but importing immigrants to maintain the status quo is not a good arguement. Somewhere along the line, the immigrants will require exactly the same and the problem increases exponentially. The solution to this problem requires...

    Batteries

    A 15Ah battery would give you 50% greater range and 50% heavier battery. Only you can say whether this would be better for you.

    Suspension seatpost

    My instinct originally was to go for the soft spring, but having now watched a few videos of the seatpost in action, I'll probably go for the medium. Most riders said they had to tighten up the tension (even for 68kg), so I expect it will be good for my 60kg. EDIT: I went ahead and made the...

    Suspension seatpost

    That's great to know. At least it'll only cost a tenner to rectify a bad decision. Thanks.

    Suspension seatpost

    I just went to purchase a Suntour SP12-NCX and discovered that there are three variations available - soft, medium and hard. Being 9 and a half stone (60kg), I am at the threshold between the soft and medium seatposts, which is 60-65kg. I have always struggled with my weight and was a little...
