I have never heard of anyone doing partial charges as being normal, the people I know here with e-bikes, make sure they charge to full once the charge is less than enough for their needs. I have recommended to them to remove the charge cycle once the green LED goes on, as I have also had first...

This link you may find interesting, it details clearly why leaving Li-ion batteries on a charger, is not a good idea for the long term life of the battery. Something I have experienced, but many do not believe! https://batteryuniversity.com/learn/article/charging_lithium_ion_batteries Best of...

Firstly, love you answer/information, nobody could guess that, you have to know that! I am sure that the OP is most grateful, and I know that I have learned a lot today about PAS sensors!! They can be far more complicated than I ever imagined.... May I ask you to take the time, to write a...

It is possibly all in one unit. How many wires go to the sensor? regards Andy

I really think everything is OK, and its just the fine adjustment. Did you see two sensors, or only one? regards Andy

I've not had the problem itself, but I know electronics, so I do believe that there are two sensory, and the timing relationship between them decides if the pedal movement is for forwards or not. I would imagine that the distance between the sensors is important,but only move one say 2.5 mm, in...

I understand your wishes fully, but what does a USB charging really mean, just that the light will be more expensive, and just as easily stolen as a cheap one....depending on where you park the bike of course. And unless you have a USB charging station on your bike (I have one myself), you still...

Its the same everywhere, you contact the post office, any parcel services and inquire. Or you search them out online, I like this one:-...

Firstly I have never done it, sorry! But for the price some of the companies take here, I could drive there and back fuel wise, in Germany......and I have then no worries about it getting damaged either..... Find out what it costs and get it well insured!Let us know what you decide and why...

Batteries do not like to be charged too fast, but only Bosch can answer your question 100% accurately. I personally prefer a 2 amp charger for any Li-ion battery.... But is a second charger such a problem to take with you? If the one charger you take "dies" on you at the beginning (or middle) of...

Re-celling by a good company, with top quality new cells is usually the best way to go, I myself like Panasonic cells, but there are several good makes.... If you are electrically trained/knowledgeable, you can do it yourself, but never forget that such cells can be dangerous if badly treated...

I agree entirely. Many modern laptops need more current than that! No need to be discreet, or is there some silly Byelaw about what can be plugged in? regards Andy

Always, with any sort of power problem, measure the battery voltage with a known good multi-meter, check against another occasionally, and replace the battery if the results are not what you expect. If you need assistance with any problem here, tell us that voltage value, and also mention the so...

The positive of the charger, needs to connect to the positive of the battery. What does the label on the charger show, there is usually a tiny graphic depicting which part of the connector is plus and minus. If this is the opposite to what you are measuring, you have a problem!! You might like...

Do remember, especially with Chinese made equipment, they do not always stick with the correct colours of leads, which has cost many dearly!!! Do not forget this!! It does sound as though the charger needs the polarity (connector) changing!! It depends upon the type of meter. Older style with a...

The very first job is actually to accurately measure the exact battery voltage first! On both Batteries. When a Li-ion battery has not been used/charged for a long time, remember it discharges slowly and eventually goes below a certain value, and the normal charger will not charge it, but shows...

You might want to run your hand around the inside of the tyre, to check for thorns still "hidden" in the trad, that are only apparent when the inner tub is blown up and the tyre is stretched. I had one like that years ago, also on a rear tyre! Very annoying! Always mark the place where the valve...

You are right, as some controllers are "programmable" for both voltage and maximum current, it might have accidentally changed itself! A check would be a great idea. regards Andy

Sounds very possible.

The voltages you quote, how are you measuring them? If a bike display, they might be wrong. If you are using a voltmeter, check its battery is still good, and then compare it to a known good meter, both on the same voltage source, just in case yours is bad. If everything is accurate, then as...
