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.

Don't charge near an escape route, and near freezing I've read you should reduce the controller current if possible. As said a fire needs a cause and the BMS should protect against any misuse. So in theory the culprits ought to be either storing a full battery unused for an exceptionally long...

This. For cell protection to be reliable it must be inside the battery, not reliant on user training or on protocols like plug shapes or stickers. Which is not to say that those can't improve safety. With the market buying on price and scant product details and the brands pushing proprietary...

If this is the XL830L the 200V range only resolves to 0.1V. It's best to calibrate as near as you can get to the voltage you want to measure and using the same range, but I haven't found a reference above 10V off the shelf.

If you did want to stick with the rack battery there are plenty of crossbar bags made for cell packs, you could take the pack out and it would be a fair bit smaller, but that's for fair weather and gentle use. I'd sooner bungee the case in proven place on the downtube just to try it out, and...
