the throttle + pedalling = legal + precise control of the amount of assistance, from snail's pace (negotiating gates for example) to 15.5mph while pedalling as little or as much as you like. A combination often overlooked because difficult to explain to the police and most people don't need the...

16.2mm is OK, the sensor won't crack, just jiggle the sensor case a bit to fit it better. Post a picture of the splines on the bb cup if you want me to check.

I noticed that point in your experiment but you have not yet repeated the same experiment with Sturmey 's diode idea.

I think there is strong interest in charging at 41v in order to prolong life of the battery and reduce fire risk during charging. However, the cost needs to be quantified, how much loss in capacity? I can get 41v chargers made.

Can you make a discharge curve like saneagle's in the other thread?

the charger has CC-CV function

You have to deduct National insurance and income tax, management cost repairs and insurance etc there is little left if you have to pay the mortgage.

You can't because of the molding. The middle blade is the polarisation key. It is placed in slightly nearer to one side in the 18v

properties tie you down for a very long time though. Personally, I dislike dealing with tenants rents, maintenance, refurb etc on top of taxes.

They have the same physical size but the polarisation key makes sure you can't use them in the wrong adapter

a fast charger is an attractive proposition but should we warn potential takers that fast charging accelerates the ageing of your battery?

burping is enough if you are careful not losing any liquid.

don't forget the issue of public liability whenever you put something in the market. If the bike battery sets fire to their garage, you may be jointly liable.

has anyone got time to run another e-bike company?

so I thought...There are actually millions of tool batteries languishing in garages.

It's free from the point of view of the customer. He already has the battery in his lawnmower

Those tool batteries are made with chemistry to allow fast charge.

Shanshan makes the case but not the pack inside. You need to test the pins with a tester before you drop the battery in.

Yes, it's straight forward but you need to make sure that the positive and negative pins are the same.

Yes, I did. There are dewalt, makita etc the Chinese company I contacted has similar adapters for other batteries. it would be much better to make my old mold for the downtube on the long run.
