Cells amp rating is tricky although rated for 10a it will not last long running at 10a and life will be shortened, the max amp rating is a short burst rating. Generally one should be looking at a max 60/70% of the call amp rating or follow the battery spec guidance. If a manufacturer rated a...

A good spot. A battery at 80% SOH, one could declare it is waning and and not far from recycling. One at 90% is half way to being at end of life.

You haven't been following the furry badger thread then!!!! Injuries sustained were quite serious and a longish road yet to recovery.

If the voltage on the jack reads 42v then there is nothing wrong with it. Read the battery manual to see if the battery is in sleep mode as it hasn't been charged for a while, some batteries with sleep mode need a long depress of the on button for 10 - 30 odd secs to wake them up. The wake up...

Plug the charger in to the wall and switch on, the two pins at a 3 oclock & 9 oclock are the v+ & v- on the charge jack. Carefully put your meter probes on them and tell us the voltage, just don't short the two jack ins together.

So the pics in #12 weren't the charger but the battery docking connection. Show us the correct charger pic.

One would have to carry out a voltage test on the halls to find out, usually a duff hall does mean no motor power, ebike systems use a 5v rail for peripheral's using halls.

Bottom Bracket.

More current will reduce battery life and not all cells used will like a 4 or 6a charge, it will depend on the cell spec's.

Footpump replaced the TS with a traditional cadence sensor and a new BB. One can buy TS BB and controller kits but they work out at about £200. With the KT on gets 5 power levels using current control, if one wanted to there is OSF programming that can preprogrammes KT signwave controllers...

Forum member footpump I think was the first to retro fit an e - crossfire with a KT controller system on thus forum.

We have had guys in here replace the Suntou controller/display with another brand and successfully use the suntour hub and battery. In your case E42 is motor hall failure, as the motor isn't working any way it is worth opening and replacing the hall sensor. Hall sensor is about £3- £4 as I...

Knackered battery or one out of balance, what is the voltage reading fully charged ? It is typical of an old battery to have the voltage collapse or sag horribly even when fully charged, when this occurs it is usually a sign of aging and ready for recycling. 10 years is a good life span for...

Hub motors have proved to be pretty much ultra reliable for me over the last seven years or so, more so then the mid drives I have fitted with both having failures to the controllers three mid drive units and four controllers. All diy bikes using bog std mechanical parts means nothing is off the...

I have never yet built a wheel using L or R different lengths, even with dishing I still use the same spokes.

It may use extra comm's wiring as it has 4 extra pins so you might not get a reading. One assumed the meter was set to 200v DC. One could open the charger to check for a blown fuse if fitted/used, if the clicking noise to the charger is with no battery connected then it indicates power supply...

Do it your self easier and about the same price without waiting, tools are about £5 and a cassette about £30 - £40, time to do the job 10 - 15 mins .

It is the current flow that causes the warmth rather then voltage.

Didn't have my thinking head on last night and it has just registered this is a mid drive Bosh bike as well. If under warranty get Halfords to repair it or if out of warranty do it your self.
