Mac motor, em3ev battery, 56t ring, CA V3, ebrakes, etc...

Post by Peterfr12 » Jul 28 2019 3:25pm

I am building a new ebike with a MXUS motor, 12F nucular controller and a 20s14p battery with a new 80t ring and ENO freewheel. Hence, I need to get rid of my former ebike kit and other goodies which has been unused the last 6 months.

EM3EV KIT with 9684 km on it used only on Tarmac in UK. Kit was purchased in June 2016.

MAC hub motor 8t laced to a new black 26 inch Halo SAS rim (at 5000 km) and fitted with a brand new 365 Schwalbe marathon tyre (0 km on it). Dropout: 135 mm. Motor has been fitted with a new clutch at 5000 km. It includes the DNP 11t 7speed freewheel and two torque arms and 2 brand new nuts and a new electric plug. The Halo SAS is a very strong rim. I have no issue with this wheel. Price : 140£ negotiable

DC DC converter from em3ev. Never been used. still wrapped in plastic. 7£

One 14s9p battery. 58V 27Ah with 80A BMS; 30Q cells. Rcold= 0.016 ohm; Rmax=0.070 ohms after 30 miles . At least 215 cycles as I forget to reset the battery after charging it several times. Always charged at 80% and never discharged below 20%. When new I could cover 30 miles with only 11 Ah @ 30 mph. The battery is still working well and I can cover 30 miles easily @ 30mph while charging it at 80%. However, it seems that a row of cells has been disconnected as suddenly the voltage dropped to 54V when I pulled 40A in January 2019, and then the voltage decreases continuously slowly from 54V to 51V. I have not opened the battery. For someone who can solder, it will be really a good bargain. 200£ negotiable.

Hi John,

My top speed with a battery (14s9p) charged at 80% was 35 mph with a recumbent bike, 31 mph with a diamond frame.

Where are you based, i am in hertfordshire? I made an offer to someone who wants to purchase the wheel, CA, controller and also the big battery. if he refused it, I will come back to you.

Best regards,

Peterfr

Thanks.

Re the battery if someone can help out on the voltage drop?..

The reason I ask is I believe they are spot welded, unlikely a cold solder fix?. Also read 30q cells don't last too long, which brings me to the conclusion some cells have failed? Is this an easy fix,find?.. I'm interested in buying but need to be sure what I'm buying?.
