no, you are not very lucky with this. Did you contact support? what did they say?

unless I am mistaken, some 2008 Kalkhoff Agattu sold by 50Cycles are still running with their original 26V 10AH Lithium Mn battery.

current batteries use Lithium intercalation. Perhaps soon we'll see Lithium alloy then fuel cells.

the reason that laptop and mobile phone batteries lose their capacity in 3 years is because we keep charging them all the time, even every day. Some e-bike batteries made in 2008 are still running now, 6 years on.

if you look at life expectancy, then factors like number of points of failures are important. In my example, the failure was due to a stainless screw that was not plated well enough, got corroded then the rust caused humidity to short the screw to the PCB where it joined steel to copper and...

I took the picture below from a dead battery made in 2011. Note the corroded screw and PCB at the bottom right corner. Humidity condensed inside the casing, attacked the screw then shorted out the battery meter. The battery was completely drained last winter. The pack is unrepairable.

corrosion happens whenever you have two different metals that are shorted by humidity like in the picture below, taken inside a car: The same thing happens at the charging port of any e-bike battery. You don't need that much corrosion to kill a BMS. Plus, you have copper, tin and lead in any...

even with current technology, the life expectancy of the electronics (BMS) is shorter than that of the Lithium ion cells. Most of the time, your battery dies because the BMS fails. The bike is exposed to weather, humidity gets inside the battery and corrodes surface mount electronic components.

if you want to charge your average 36V 10AH battery in two minutes at 70%, that will require 7A * 30 = 210A charging current, at 42V that will require a 8.8KW feed. It's doable but not indoors, unpractical as Mike said. The more sensible approach is to use fuel cells. One litre of petrol or...

Viruses are by far the most abundant biological entities on Earth and they outnumber all the others put together - therefore the vast majority are benign. I suspect that the most dangerous viruses could have been genetically mofified.

the 'invention' isn't really new. A lot of effort are being made to develop nanotubes for batteries. What's new in this case is possibly a cheaper way of making TiO2 nanotubes. The one I like best is to get viruses building your nanowires for batteries:

unless i am mistaken, the Giant'sbattery is 27V, it won't work well with a BBS01.

Stuart, looking at this bike objectively for what it's worth in components: bike? £100, motor? £60 controller and wiring? £30 battery? this is a big issue. The battery is probably due for replacement. I think £480 is too much. £250-£300 is a fair price for a working bike of this age.

you can check which wire has 5V, usually red, which is ground, usually black. You only need connecting ground and signal to the brake switch.

if you have 3 wires on the controller side, two of the wires are ground and 5V supply, the third wire is the signal. There are two possibilities: brake signal is active low or active high. You need to find that out first. If it's active low, then it's easy, just ignore the 5V wire.

the 2011 Sirocco motor has Hall wires, 2012 (and later) Sirocco has 8Fun SWX motor without Hall. It's easy to know which one is which, the motor connector with Hall is a large square, the 2012 Sirocco has round, small 3-pin connector.

take away £1000 for the motor and battery, the frame and two air bags cost £10k?

12.5kgs? and the price is.. £3,299 I am just guessing.

that bit is not hard, QR front wheel, remove the stem and saddle if they get in the way.

Southend sea front has the longest pier, lots of cheap eats and a 7 mile cycle route. You can leave your car in their car park and your OH borrow a bike from their shop.
