Hi,
I am considering this battery:
http://www.ebikes.ca/shop/electric-bicycle-parts/batteries/b5216-lim-dt.html
I wanted to find more detailed specs about those cells, but the official ones are very, very shallow.
For example, it writes only "standard" charge rate at 0.5C, and I am interested in:
1. The maximum continuously allowed charge rate.
2. The maximum peak charge rate. (Regen peak currents)
I rely heavily on regen on all my E-bikes in the hilly city I live, and I can reach braking powers in the order of 1000W for the small-powered bike, to above 2000W on the "armed to the teeth" one.
My current batteries are A123 20Ah prismatic cells, which are perfect for regen (up to 4C continuous), but sucks at mechanical properties like vibration-tolerance, their weight and volume.
Do anyone know where to find detailed specs about the NCR18650GA like A123 provides?
I also consider the 30Q cells by Samsung, which em3ev sells. Their packs are also cheaper, too.
Searching for information about them here vs the other 18650's gives you a jungle of information, with overwhelming page results which I have no time to read... (especially that most topics go off-topics eventually!) Also, none which I found talks about what I asked.
So I thought to ask here, if you recommend the Panasonic NCR18650GA ones, or the 30Q by Samsung?
My 1st priority is the ability to consume large regen currents, 2nd is the life cycle count.
