    Help! Controller - speed or current? Carrera Kraken conversion?

    it's not a limitation by Lishui. They supply the code to suit OEMs. Their default code is practical for most users. It's not an on/off switch based on speed, it's a step change in effort based on the selected assist level. The main difference in the Lishui's 'speed control' - for lack of a...

    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...

    Charging pack to 41V experiment

    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.

    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

    E-Bikes: The phenomenon, The Problem.

    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

    Batteries Charging Routine

    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.

    Battery upgrade

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