What all vehicles can we use battery cells from?

You can use NiMh modules from 2020 AWDe (like mine) and maybe other AWDe Prii through 2023.

Gonna be tough to find . The wait will be an issue . You got to try and find it in your area so you can go put your eyes on it before you plop down your money because sellers will take a dump on you and you'll have no recourse the sellers have gotten wise they understand what they need to do all that stuff so depending upon your market should be sometime lot of salvage yards don't communicate anymore and don't ship stuff around the places so you have to be careful seems like all the dilly-dally and around what have you and what you're going to pay for that buying a new battery before the price increase should have been the thing I guess.

 

If you are looking to get the most fresh NIMH battery modules than you have the only option which is Toyota Corolla up to 2022.

 

yes, it's essentially identical to the Gen 4 Prius NiMH pack. There's plenty of them here in the $750 ish range. Just be sure to verify it's an NiMH battery, not the Lithium

Any modern hybrid Toyota car with a high-voltage NiMH battery uses the same modules - 7.2V 6.5Ah. In different cars, the number of modules is from 20 to 38 per battery.
Prius Gen2 requires 28 modules.

 

At 40k and 4 years miles the pack should be good to go. Just measure each module voltage and make sure that they are all within 0.1 volt. If so, just install the "new" modules.

the end clamps are not interchangeable. Move just the modules to your Gen 2 pack

 

No, forget it. This process is called equalisation, not balancing. In essence, it doesn't do anything useful because there is just not enough potential difference between modules to move enough electrons to do anything of worth.

Please if you could explain what are the differences equalization and balancing. And why it's different for NiMH and Lithium.

 

I don't know much about lithium, but from what little I know, what works for NiMH does not carry over to Lithium.

Very simply, equalization is simply just trying to make the voltages of all modules the same.

Balancing is the process of gently (over)charging a module (at 0.05C or 325 mA for Prius 6.5 mAh modules) so that each cell within reaches a fully charged state and then discharging down to a set voltage. This is repeated 3 (or so) times with each subsequent discharge to a lower voltage. Some advocate 1 volt per cell for the first discharge; 0.8 volts per cell for the second; and 0.5 volts per cell for the third discharge. Some say going lower than 1 v per cell will destroy the module, but my experience is that unless you go to at least 0.8 volts per cell you are not going to break up any crystalline formation on the battery plates and restore the battery to its optimal capacity.

After doing a proper balancing you might find that the voltages of the modules have diverged wider. If this happens, it highlights the difference in the capacity of the modules. To make a successful battery repair all modules at the end of the balancing process should be within 0.1 volt of each other once the surface charge has been dissipated. Furthermore, after sitting for several days, they should not significantly self-discharge or diverge from each other.

There are plenty of threads on PC with the details of how to do the balancing procedure.

 

Thanks, I like the way you explained that and the concept works for both stick and pack based reconditioning. Only difference between the two, stick and pack conditioning are the charge / discharge machine settings.
My take on your description here is that this part is the meat and potatoes.

While this part is the gravy.
