Hey there
Its been a while since ive been on here...I purchased a test set of prismatic LifePo4 cells, 50 ah to test on a test bike (Emmo DX), , The cells measure about 165 mm tall by 135 mm wide and about 31 mm thick.
I wanted to test these on an ebike so I built a 72 volt pack. .
I designed some batt tops for them and installed in the bike after upgrading the wiring.
I got the following results...On an 80 kph rural stretch heading into London, I kept the bike at around 60 KPH and sometimes higher, but never below 55. I got into town and showed the bike to the ebike owners and customers, and then proceeded back, this time at 50 KPH as I didnt know if it would make it back. Not only did it make it back (112 kms), but by my calculation on voltage it had about 20% left. This is a heavy relatively big bike and by my estimate of 33 Wh/Km the cells are accurate with respect to being 50 ah.
So here is my question..I am going to be ordering aprox 300 of these, as I got a bit of a deal and have had requests for battery packs but if demand doesnt match my stock, then if anyone is interested in purchasing these from me, I will sell at the price I bought them for. Let me know.
