Hello,
This is only my second post. I've read a couple threads on ES on various battery packs and cells and I narrowed down to a couple options.
I would like some advice or feedback you could give on the next few cells. They may not be the best, but they are the ones that ship to France. I would very much like to get some A123 cells, but I have to choose from these:
1. 18650: Microvast mv18650fpca http://www.ebay.com/itm/LiFePO4-18650-battery-3-2V-30A-1100mAh-Power-Battery-Cell-LiFe-w-tabs-3-2-Volt-/320948578691?pt=US_Rechargeable_Batteries&hash=item4aba06a983
2. 18650: Phet pat.C http://www.ebay.com/itm/PHET-PAT-C-LiFePO4-18650-3-7V-Rechargeable-Battery-/130773264801?pt=US_Rechargeable_Batteries&hash=item1e72b1a9a1
3. 26650: http://www.ebay.com/itm/1pc-3-2V-LiFePO4-Li-ion-LFP26650-energy-type-3200mAh-flat-cap-battery-cell-/271225694535?pt=US_Rechargeable_Batteries&hash=item3f264fa947
For the first two I even found data-sheets. The Microvast cell has soldered contacts, so it would be easier to integrate it in a pack. The third one seems to be more no-name, has high energy, but lower C-rating for discharge. The pack may see bursts of 3C load, but in general it should work at 0.3-0.7C.
The battery pack will be part of a very light-assisted ebike project. Do you have any info or opinions on these cells, or are there others that (even if more expensive) would be worth considering?
Thanks for reading,
D.
