TSDZ2 750w losing power on hills

[Sasquatch260]

In my experience with undersized and older batteries, when they get worn out, there is a large voltage sag on the cells and either the battery or the controller shuts down.

It's true that higher voltage is more efficient in an ebike, but your heat came from an undersized motor spinning too slow, not from not enough voltage, Much as I like my TSDZ2, my BBS02B laughs at it when pulling power is needed.

A new battery is always nice, but get it somewhere other than the lowest price guy, .

Ok. Good advice. ... And the 13 ah that I have is okay for the TDSZ8?

Just try it and see.
Your battery should still work at least well enough to use until your new battery arrives if you need one.

Buying the battery separately is a Really Good Idea, anyway.
Even if you have free returns from wherever you buy your battery, that probably doesn't include shipping.

Mailing a battery back to China requires HAZMAT shipping and has to be shipped by 🛥
That can be REALLY expensive and it can take Months to get your battery shipped back to you.


I bought a 48V 25ah battery from this vendor.
They can build a quality battery that will fit almost any ebike you have.

I'm not sure about proprietary batteries though?

In 2021 when i bought my 48v 21Ah I paid €416, which I think was a good price.

The close up picture of the motor that you posted looks to have a lot of corrosion including a severly rusted tension relief strap screw. Out of curiosity, does your tsdz2 look as bad as the one in this disassembly video? If so it might have lived a hard life and just reached the end of its usable lifespan.

Depending on the type of bike you ride just buying a new discounted Yamaha Cross Core RC might be an good choice since you would get an entirely new, good quality, UL certified bike with warranty for $1199. Too bad they don't still include a free second battery, that was an unbeatable deal.

Mine looks much better on the outside but worse on the inside. I definitely worked it hard.
Yeah that Yamaha is nice.

I'd get a Yamaha but I'd want this one and it'd be 7-10 thousand dollars with tax in Canada??


I dunno?
I thought that they were on sale ??

Add it to your cart to see the discount

Stock at a local Yamaha dealer is getting very thin but they have a YDX Moro for $1919 USD ($2745 CAD). If you live close enough to a US dealer with stock maybe it'd be worth the drive?

I just posted a real-time discussion about the DMO2. It kicks butt. It took me awhile to get up on the programing curve.

I'll check it out. Is it torque sensing like the TDSZ or cadence?

 

[harryS]

DM02 is torque sensing, but probably has a cadence mode.

There is a cadence sensor in the TSDZ2. The OSF third party firmware offers a cadence priority mode which I optioned into my wife's bike. Works really well. When I ride it, I am surprised how much more easier it pedals than mine in T/S mode,

Here's some good info on the different motors available.

Yeah, I really like my torque sensing DD hub motor bike. It has no more noise than non-motorized bicycle. It will do 28 mph on throttle alone, though I like to pedal and shift through the gears. Pedaling and it's a super quiet bike. The downside is at 62 pounds it's 10 pound heavier than my...
