As the Hub Motor Turns and the LiPo Fire Burns. What is a fanny pack good for ????? :lol:
answer.
1S - 5P - LIFEPO4 strapped to the handle bars.
Yea. I just can not live with the fact the Currie will not go 30 mph on the flat.
The Voltage SAG is just too much with 12S - LIFEPO4. I did see 28 mph and 27 mph though. Two different GPS speedometer apps.
The power meter clearly reads 34V under load. I think I saw it SAG to 33 for a second as well. If I add 3.5V to 34V that will be 37.5 and 36.5 if SAG voltage is 33V.
Since the 36V 1,000W chain drive is rated at 3,000 rpm at 36V then it is possible to hit 30 mph at 13S or 3.55V * 13 = 46.15V.
Fully charged voltage is 47.4V for 13S but at 97 to 98% is closer to 46V. After SAG should be > 36V and 30 mph.
I will need to order one more box of 15 - K2 energy cells. Also I can buy 2 or 3 fanny packs so when I recharge at 12S out on the road I will have one or two 1S - 5P packs in my back pack to swap out for 13S - 5P.
Yes. I am patting myself on the back for being a true genius.
Thanks.
