Hey There, I just put my first 2 packs that I built from second life cellsin the Cell counter and there was a link to post your projects here.
So my first project is replacing Ni-Mh battery packs in some of my old Electric Gliders and RC planes. I just made 2 3S x 1P battery packs for a total of 6 cells. I used the lowest mAh cells thatstill took a charge and resistance was less than 400 milli-ohms. Even though these were the lowest performance cells, they are still alot better than the Ni-mh cells that I replaced.
2 other Projects--The onesthat actually got me into this are building a portable AC inverter/battery pack, that we can take camping or off grid, or we can run AC on during power outages during hurricane and storms etc.
The final and biggest one is making battery banks for a hybrid 27' ski boat with a small cabin and or kitchen. I want to be able to have solar panels, and run the electric drive motors, and have a powerwall type system in the boat, to charge the boat or run our house when the boat is just sitting in the yard or at the dock. I am still crunching the numbers for how big of a battery bank, how many solar panels, how large of a generator to get and all that. Right now I am estimating a battery bank of 75 KwH and 40S total (144 nominal Volts).
I am planning to practice on all the small projects, and scale up everything as I accumulate more cells. One example will be building the battery pack /ac inverter the same size as a module for the boat, and getting a 300 watt solar panel to charge the module, and experiment with what BMSs, and all the other stuff.
My other totals so far:
So far I have 24 tested second life batteries that are good enough to use and catalog. I just got 10 battery packs today and retrieved 78 cells from those and am testing those now. And I have 22 new Samsung 30Q that I am going use in the boat.
I will probably set up a blog soon too, and will link it here.
Cheers,
Ryan "Rip"
