Re: EBike wireless standard (like Specialized Turbo Levo) -- Flexible OpenSource firmware and mobile app

Keep it going guys, always fascinates me how you programmers can code as you do and get results despite the lack of documentation and the likes from the manufacturers and other coders.

Big thanks from all of us for your endeavours in this really exciting application for the TSDZ2 engine.

Re: TSDZ2 open source firmware only for KT-LCD3 (v0.19.0 / v.0.20.0beta1)

Hi All. My old faithful LCD3 with V20 has died. I have had a dead short between the batt pin and the next pin beside it on an 8 pin connector, it was a dead short and has blown the pin off of the female 8 connector Batt voltage pin and fried the male connector at that point. Now I had been riding in...

Re: New "TSDZ2 Torque Sensor Central Motor"

The only time we have seen motor current draw problems was both times a battery fault. Turned out to be a poor weld on some of the cells which was restricting the current, as soon as you stopped or at rest the voltage would recover back to the norm.

Re: New "TSDZ2 Torque Sensor Central Motor"

I've replaced two now without using locktight and without problem. Just be aware as with all press fit bearings, if it pushes in without much effort then do use a locking agent. Also note it will cost you a lot more too get the correct bearing with the O ring indentation, I've been using the standar...

Re: Shipping Dengfu E10 frame to England

Yes its sitting on my bench waiting to try and locate a M500 motor, looks really good quality and in some ways overly built. Bit chunky looking on the front downtube but everything else looks really good. Melody at Dengfu organised a deal that it came over by train and boat and took about 4 weeks, b...

Re: New "TSDZ2 Torque Sensor Central Motor"

So stick with hub motors, whats the problem ? In my useage I would destroy a hub motor on probably the first ride, we do a lot of low speed climbing where the hub motor would be only rotating a few 10's of rpm at near full power, the heat generated would cook every bearing in it. If we used a geared...

I think I remember someone has run the M500 on 48 volts or even 52 volts, can anyone confirm this as all my packs are 52 volts and it will be a pain to have to change them.

Re: New "TSDZ2 Torque Sensor Central Motor"

You obviously dont fix bikes then, they are not the most reliable of things. To put things into perspective I have more things fail on my bike than I do the motor, so I guess on a bike measure of relaibility,the motor is more relaible than a bike.

Where’s the market where you are going to sell max number of motor conversions, the Asian commuter where a cadence of 60 is high, so do you then concentrate your design on full on cyclists who have a cadence of 100 and number just a few thousand, nope you hit the market where you can sell a few mill...

Re: Economical intelligent charger for 14S2P packs

It may sound that my battery balance regime may seem a bit agricultural compared to yours at 0.001 volts, but this is how I’ve been doing things. Correct me if I’m doing it wrong. I have been looking at the fully discharged ( where the BMS low cell voltage has tripped ) voltage of each pairs of cell...

We had been running Samsung 30Q’s as 14S2P without problems @ 12A max across the 2 cells without problem but have recently gone across to Samsung 35E’s using the same BMS’s to get the larger capacity and more so now availability. The 8A max on each cell of the 35E’s was always a push at the 12A we h...

Economical intelligent charger for 14S2P packs

Hi, Getting into problems with cells coming out of balance from the packs being used hard ( Ebike ) and being used until the lower voltage is being reached. It would seem that after a few months of this type of useage 1 or 2 groups of the 2P ( we need small light weight packs ) get to a stage where ...

12 volt LiFePO4 50 amp battery build.

Looking through the forum, I can't seem to find much on building a LiFePO4 12 volt replacement leisure battery of about 50 - 60 amps. Anyone built one and why so few as they would seem pretty much an ideal replacement if a B2B charger is used off an alternator or even say a 200W panel over the day.

Did you guys receive the front downtube cover or is that part of the battery case. I plan to use existing 52 volt batteries I already have and will need someway to cover over the battery compartment.
