    Grin Satiator: Any way to force battery recognition'?

    I stupidly left my ebike on all night and, this morning, found the battery totally flat. Hooked up the Satiator but, even after being connected for 3 hours, it is not recognizing the battery as being connected. Is there any way to force the charger to start charging?

    TSDZ2 Large Sprag Clutch: What Causes Wear?

    Not the clutch in the blue gear, but the larger one. Is it worn more, the more hours that the motor is assisting? Vice-versa? Is the failure mode sudden/total or gradual? Mainly, can failure strand the rider by rendering the bike not pedal-able even without motor assist? Finally, can...

    TSDZ2: Calibration for Real-World Human Power?

    I am trying to set up my TSDZ2 w/aftermarket firmware so that the "Human Power" readout bears some relation to reality. Not having access to any of the bike power meters, I am fiddling around with Settings.Torque Sensor.Weight on Pedal and one of the Settings.Assist Levels.Power Assist values...

    TSDZ2: How to Set Odometer?

    Open-Source Firmware Version 20.1c-22 When I go to Settings/Various/Odometer and change the number, it jumps to 1,400-and-some miles when I exit "Change" mode. IIRC, I succeeded in changing the odometer value once in the past, but do not recall doing anything different. What might I be missing?

    TSDZ2 OSF: Unable to Change Odometer

    At first I thought it was my 860c being on the way out. Then it failed completely and I flashed/installed a new one. But, even with the new 860c, I am unable to change the Odometer value. It increments & decrements while in Edit mode, but reverts to the original value when I exit Edit mode...

    TSDZ2: Is my use Light, Medium, or Heavy? Maintainence Schedule?

    TSDZ2 mounted on a ICE Adventure HD tadpole trike running through a Rohloff 14-speed hub. Trike + rider = 308#. No throttle connected, PedElec only. Used mainly to help on hills and against headwinds once I start to feel like I am "Grinding". Typical range w/that use on a "52V 14AH... 40...

    TSDZ2 blue nylon gear: failure mode?

    Does the blue nylon gear on Tongsheng's TSDZ2 tend to fail catestrophically/totally or gradually? i.e. does it give off warning noises vibrations that tell one that it needs replacing, or does it tend to just totally strip the teeth?

    TSDZ2: Pre-emptive blue nylon gear replacement?

    Can anybody cite a number of miles for pre-emptive replacement of the blue nylon gear on Tongsheng's TSDZ2? One guy said he does it at 800 miles, but his use case seemed extreme compared to mine. I have mine mounted on a tadpole trike, capped at 400w, and used as seldom as I can - mainly when...

    How to maximize battery shelf life?

    INR (lithium nickel manganese) chemistry. I have two batteries and it turns out that each one has more miles in it than I do, so I want to store one against the day that the other wears out. Assuming a life of 500 full charge/discharge cycles and keeping the active battery between 20 and 80...

    Hard-Wiring Battery Mount into Trike?

    Right now, my battery slides into a mount, out of which comes a 10-gauge wire. In use, the 10-guage wire is connected to the trike system via Anderson Powerpole connectors. The trike's system consists of a TSDZ2/OSF mid-drive and a 4-watt LED glow whip/flagpole. Eventually headlight and tail...

    Cycle Satiator: How Precise Watt Hours?

    Each time I charge my lithium battery, I compare the number of watt-hours that the TSDZ2 w/OSF reported used before charging with the number of WH the Grin Satiator says were put back into the battery to get it back up to 80%. Sometimes the numbers are not even close, as in 49/97, 44/69, and...

    Noise-Reducing Grease?

    I dropped a bundle on a tube of M23 grease with an eye to giving my TSDZ2 the best there is when it came time to replace the nylon gear and maybe install a temperature sensor. But then I started reading about greases that are specifically formulated to reduce noise. Is it worthwhile to seek...

    TSDZ2: Rider Torque Suddenly High?

    Today, I started seeing ludicrous torque numbers for my own input. Used tb 125-200 watts - which seems believable. Now, suddenly I am seeing 400-500. Can anybody suggest where I should look? Hardware? Software? (mine is flashed with OSF). FWIW, torque has never been calibrated.

    350 Watts Max, 4' Run: Is 10-Gauge Worthwhile?

    Is is worth the time and trouble to replace the four feet of existing 16-gauge wire from battery to motor on my trike with 10-gauge if the motor is limited to 350 watts/7 amps? 52-volt battery, TSDZ2 motor.

    TSDZ2/OSF: How reliable is the watt hours reading?

    I an trying to benchmark a recently-purchased "52V 14Ah/728Wh (Samsung 35E/14S4P)" battery. But my numbers are not even beginning to add up. To Wit: Discharging from 56.8V (a little over 85% charged) down to 45.4V (20% charged) got me 24.2 miles, and supposedly used 235 Wh. Discharging from...

    Recumbent Trike as Legal Wheelchair?

    Have you ever heard of a disabled person getting their e-assisted recumbent trike legally classified as a wheelchair? I am thinking in terms of protection under the Americans With Disabilities Act.

    TSDZ2/OSF: Does torque sensor calibration affect Human Power?

    860c: 20.1c-22 TSDZ2: 0.20.1 As an 80+ year-old user, I find it hard to believe that I can put out 220+ watts in a sprint and 150 sustained. Do I need to go through the Torque Sensor Calibration procedure to get more correct values? If so, can anybody point me to a "Torque Calibration for...

    Are Anderson PowerPole connectors the de-facto standard?

    I have been using Anderson PowerPoles, but to me, they look less than optimal: A bit too easy to disconnect. Not weatherproof - as in extended exposure to a driving rain and/or seashore conditions Or are those considerations moot in the real world? If not, what are you using?

    TSDZ2/OSF: Watt Hours per Mile Running Average?

    Seems like some sort of running total for Watt Hours - either overall or per-ride - would be useful to many riders. I see Instantaneous Watt Hours and I see Odometer, but nothing in the way of totals or averages. Is it there and I'm not seeing it?

    Basic, non-tandem, Rohloff Hub: How many watts?

    I have a Newton-Meters number, but don't know enough to relate it to watts - which I can control and view in realtime on my TSDZ2/OSF. I figure that my personal output maxes at 200 watts and have my mid-drive limited to 300 - giving a worst-case scenario of 500 watts. How many watts can I...

    TSDZ2/OSF/860c: How to set up SOC for mostly charging to only 85% ?

    Firmware Versions 860c: 20.1c-22 TSDZ2: 0.20.1 My plan is to extend battery life by mostly charging my LiPo battery (https://www.electrifybike.com/collections/batteries/products/52v-40-amp-14ah-super-shark-e-bike-battery) to only 85%. "Mostly" bc I have been advised to charge it to 100% every...

    LM35DZ Temperature Sensor: Reliable Source?

    Seems like the sensible thing to do is install a temp sensor on my new TSDZ2/OSF. But I am not getting any warm fuzzies as I read Amazon reviews. Seems like there are a lot of unreliable sensors out there. Can anybody recommend a supplier? Will other sensors work?

    TSDZ2 Controller: over-volting tolerance?

    I stupidly ordered a 52v battery instead of the rated 48v to go with a TSDZ2. Given that: A 52v battery at 80% puts out 55.4 volts A 48v battery at 100% puts out 54.6 volts. I would be charging the 52v battery to only 80% What are my chances of getting away with using the 52v battery at 80%...

    TSDZ2: Installation of heat sensing?

    My understanding is that TSDZ2's firmware (with OSF?) allows for automagically cutting back on amps when a preset temperature is exceeded, but that there is no built-in temperature-sensing hardware. True dat? If so, can anybody point me to a cookbook for installing said hardware?
