Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks for the video mingonn, that sure is a lot easier than the instructions from Tongsheng. Can you let us know what the cost was for the Brass Gear? I have ordered some replacements from China & if I can get them closer to home it might save me 2 or 3 weeks & possibly shipping cost. Also, please...

Re: New "TSDZ2 Torque Sensor Central Motor"

Metal replacement gear arrived during the week and I installed it tonight. Just put a light smear of ordinary bearing grease on it, no plastic to worry about any more. To remove the blue gear I just tapped the shaft with a flat punch whilst holding the blue gear, came apart easily enough, made a lit...

Re: New "TSDZ2 Torque Sensor Central Motor"

Got the OK from PswPower to open it up. Mine came apart pretty easily, nothing too complex. Little wiggle and the motor came out easy enough too. Blue gear stripped a tooth as expected and PswPower have offered a replacement, so far they have been very helpful. I have asked for the metal one which s...

Re: TSDZ2 Blue Gear opinions

I have my fingers crossed that the brass upgrade will do the job, really like this kit but guess what you pay for it what you get. That said there are a few reports around of BB02's stripping a similar gear and those kits cost a quite a bit more.

Yup, they are fragile. Just stripped mine today, had around 700km. It runs in parallel so your effort doesn't go through it.

Re: LiPo battery care and basic information

Hi guys, I am running both my bikes on rc lipo packs but would really like an individual cell motiored LVC. I have been thinking about using rc lipo battery meters but they would have to be plugged in and un plugged after each ride if I am not mistaken. Any one know of an off the shelf LVC with adju...

Re: Folding E-Bike

Just a heads up. Most folding 20" bikes run a narrow 70mm front hub which means you will need a rear hub motor or be prepared to so some serious metal work to get the gap to 100mm.

Re: Ping problem 36V 12ah 2.0 Bulging

Another cell bites the dust. Repalced 2 100km ago now another has gone, looks like a neighbour to the one I replaced but will check tonight, I am guessing the swelling of the previous failures damaged the neighbouring cell, will pop the hood tonight and check. My pack came wrapped in heat shrink whi...

Re: RC Lipo's

Hi deanoseadog; Go lipo mate, I run a 44.4v (3x14.8v) 3800mah packs. Bought the cheapest I could find on ebay and they have done 1100 km already no problems, I haven't even had to balance charge yet as the cells have stayed within .01 of a volt. If you use deans plugs you can easily make a parallel ...

Re: LiPo batteries

Hi wilscombe, Don't be to quick to give up on replacement LiPo's. I am running RC Lipos and they have been great. If your LIPO pack already includes a BMS and hopefully a temp sensor etc it should be pretty straight forward to just replace the cells. I bought the cheapest I could find on ebay and th...

Re: Ping 2.0 Reports

My pack is made up of single cells in series, yours will have groups of 3 cells in parallel which are then wired in series. The bms manages each group as a single cell I think. I suspect that is why mine showed up so quickly, any weak cells have no where to hide. Hope Ping starts selling single cell...

Re: Ping 2.0 Reports

jha07, I have been leaving the charger on over night as ping suggests to allow the cells to balance. Straight off the charger all cells are the same but after an hour that weaker cell shows up as a slightly lower voltage. With the bms its always the weakest cell that triggers the lvc, I didn't notic...

Re: Ping 2.0 Reports

Unfortunately it's middle men like Ping who seem to be trying to provide a good product and service that are going to get burnt. I'm sure the guy is running on a shoestring compared to western standards, I doub't he has factored in alot of extra to cover dud cells. I had to replace two of mine with ...

I had two cells go bad in my v2 pack. Ping sent me 2 replacements cells and a single cell charger, I had to cover the $25us postage to australia. Its quite fiddly to swap out the cells with the hot glue securing the cells and all the sensor wires, but if you are handy with a soldering iron it will b...

All symptoms sound the same, false peak by the weak cells then upto an hour of requent pulsing (on/off) by the charger as the BMS trys to balance the pack. Weak cells then...

Re: Voicecoil's red, fully rigid commuter

Hi Voicecoils, I have 400 km up on my 20 bafang now, but my system is only 44.4 v and limited to 5.6 amps. I reckon your problems are two fold, first is wheel size and second is the current. Going 20" requires alot less torque to get moving than a 26" (I am guessing you stripped the gears on take of...

Re: Small portable fanless charger for a 48v ping pack?

Great to hear about the store and the charger Ping, look forward seeing all the goodies.

Do you think it is OK to disconnect the fan in my current 2A charger? Ambient temp here in the office never gets above 25 C.
