Sleeve the axle with 0.5mm thick aluminium rings. Many mass produced cheap consumer items use aluminium tubes, always of minimum necessary thickness.

An important technical detail highlighted by the coroner was the likelihood of a charger of the wrong voltage being plugged into the battery that ignited. 48V and 36V chargers and batteries with the same connection is an obvious problem that needs to be solved. Likewise, charging circuitry in...

Highly frustrating, but on the bright side, you only need to find a solution once, and then they never get you that way again. And your wire is not lost, there are teams of undercover operatives going around stealing them (allegedly).

There's no way back for that coat!

A mid-drive torque sensor bike still requires some input from the rider, but with the highest torque ones on their highest assistance level in the lowest gear you will not struggle. The rider input demanded is very low. 70Nm will be fine, even more gives you margin. The worst that can happen is...

A lot of the time, under load, both diodes are conducting, but with currents that may be very different. Whenever the load is light enough for the voltage at the connection point to be higher than that of one of the batteries, the other battery will take all the load, until it falls yo the level...

I give up! I thought you understood internal resistance and ohms law!

Indeed. The consistency of cells keeps the effect extremely small for a properly manufactured battery in good order.

In numbers: Take two fully charged 36V packs connected in parallel, battery one with 0.05 ohm internal resistance and battery two with 0.1 ohm. Apply 30A load. By ohms and kirchoffs laws, for voltage to stay equal where the cables join, the voltage drop across the internal resistances must be...

Yes, the voltage under load stays the same. But a higher proportion of the energy extracted comes from the pack with lower internal resistance, so its position on the discharge curve changes more than the other one. When the load is removed, the packs therefore want to be at different...

Unless the sag characteristics are identical, every time load is applied and then released there will be a degree of current flow between the batteries. The common parameter with directly connected parallel batteries is the voltage. Current under load is shared based on pack internal...

Mine is only needed for the solar, I have to fool the Shimano into not knowing it is there!

Exactly that.

Size matters... the Eleglide is showing as only in Medium, and with 27.5 wheels.

Nearly £40 and not clear what is inside. But clearly intended for what you want to do, so should work. My homemade and rather rough and ready dual diode adapter is an MBR6045WT package containing the two diodes and some connectors soldered on. The MBR6045WT is two 30A diodes, so with batteries...

Eleglide has decent battery size, simple and basic. The mountain bike part of the description only relates to styling and nobbly tyres, with hub motor it will have rather limited capability offroad. Hydraulic brakes is a plus. Metroneer. Small internal battery. Range might be disappointing...

You would need to provide details of the specific adapter you mean for anyone to give advice. Thers are many threads on here on similar topics which the search function might find for you. The basic principles are to do one of the following: 1. Use two big diodes, one in the positive cable...

The metal bit is probably a retaining nut, so it will probably unscrew, and then it will pull apart as normal.

Pictures seem to show no front brake. At 22mph, kinetic energy is more than double that at 15mph, so (a) twice as damaging in an 'off' and (b) in need of more stopping power. My vote is for don't do it.

I'd add an extra layer of protection using self-amalgamating tape. Underneath it will get a hard life.
