Great info Sturmey, I'm glad you beat me to the Edit/Retract button. Website: "When you use a 52v battery and 48v battery then the 52v battery will be used first until its voltage is the same as the 48v battery at which point the batteries will run at the same time until the 52v reaches its low...

Yeah, when I looked a few listings had FET-ty background images but all the descriptions would be met by any old diodes, so not much chance of a refund if they lose a volt. Best to ask sellers who only do bike bits and are well known, until you get a reply worth saving!

Stem 120mm -> 40mm saves 80mm, basket length ~250mm, hmm. How about a child seat clamp around the head tube so as to frame mount the basket?

So at the moment OP's friend aims to find and make do with the OTS ebike that helps the most. Is he at all open to designing the built up bike that helps him the most, or the most discretely?

A US forum user showed a hoist in use, along with a foldable (or telescopic?) wall mounted arm, a bit like a drop leaf shelf support or monitor arm. Wish I could recall how it attached to the bike.

It sounds as though a throttle's almost essential for hill starts and your TSDZ2B has that, with wide range gearing it seems ideal. Alternatively, two hub drives? Very roughly, if Eddy can climb say 6% by momentum, 22% would need two motors/controllers fit for 8% each. Reduced cooling at slow...

PCL? Put the seat on the frame mounting bracket and center the seat. Any space between the seat surface and the flat bracket fill by using Polycaprolactone plastic like InstaMorph or thick rubber. http://www.thorseat.eu/how-to-fit-seat-to-recumbent-bike

The bin gives it away, it's just another lightening project. The derailleur's no use for a reverse driven chain, the handlebars will be next to go and the reversed saddle mounted in their place. Hardly new though: The forks are correct as is, that "fight with the cables" is just to throw us...

NB that's burst current, continuous rating is about half that. If like me you disconnect the battery often the 2, 3 and 4 pole 'speakon connector's are nice to use and cheap if you look around. Not actually rated for DC but they're well engineered, work great and a waterproof version's...

Hm, inconclusive but I guess it's a regular two port BMS and doesn't rely on a proprietary charger. IIUC there might be a hack to indicate battery condition. If at random times you stop charging the battery reading should drop a LED about one time in four...? When the battery resistance...

No criticism intended, saneagle's reputation speaks for itself and he's pointed to this supplier before. Bootstrapping a business is tough, so if you go ahead @thelarkbox you would do us and the seller a favour if you'd show us the insides and perhaps fit a Wh meter with the savings to watch...

I'm not doubting saneagle's recommendation, after all he's bought batteries and the prices are good especially with free delivery. But I'm curious, how can we tell that the doubts about cell re-wrapping and the rest don't apply here? If it rests on UK supplier and 2 year warranty, companies...

I imagine that for anti-spark the BMS is turned on slowly by the inner flat pins. For charging the anti-spark circuit leaks enough to show on a voltmeter but effectively isolates the charge pins. A cheap way to do that would be to skip a charging MOSFET and use a low Vf diode, they tend to be...

Ah, the Dutch "umpire's seat" manoeuvre, still getting the hang of that :) A benefit of the sideways lean is that when you haven't noticed the ground falls away the lean keeps going until contact is made, doing the splits but still upright. I copy my cat's 'of course I meant to do that' face.

Brakes on and lean the bike works for me too, also on inclines. I thought 'step-through' was a visual term like 'kissing gate', meaning with lower stand-over height. My balance on one leg isn't great and if I aimed my size 12 through the gap I can see it slamming the frame to the ground with...

A lipo fire expels hot gas. In the smallest of fires both the zip and the velcro would be toast. Edit: How do we get an Amazon listing taken down?

Can you get these with an integral time-out and easy indication of whether that's set? I wouldn't want to go out forgetting my phone was set to send an OFF.

"Takes 6 hours to charge my battery so most nights I turn timer allowing for 2 hours charging." That's most of the battle, and begin a few hours before bed because a hot cell can take a long time to go fully rogue.
