I have followed " Emmetts " method of sealing my new 3540 using J and B black ultra RTV and used sealed Nachi bearings ! No leaks for wire side , some weeping from pressure relief hole ! Using 130 cc of synthetic transmission fluid ! The improvement in cooling is dramatic !! Climbing the 12 %...

I love Justin and the contributions he has made . My experience with Statoaid: the motor cry 3540 R with cooling fins , the test continuous acceleration with no cooling period between accelerations , start 65volts at 100 amps . Run until thermal cutoff of 110 C reached . Motor stock 17 runs ...

Chilo please be careful riding your 250 watt super bike those tricycles might run over you !

Thanks Offroader I ordered the bearings you suggested only cost $ 22 dollars delivered ! Got the size form the Grin web site 17mm x 40 mm for all H Crysolite motors !

Thanks for your brilliant god like observation Chilo . Since you are all knowing I better not waste my time doing any original thinking . My motor is not leaking at ALL from the wires , the major leak is on the opposite side of the motor . Chilo better not use statoraid it is oil based and...

Does anyone know then bearing nomenclature for they 3540 crysolite motor ? I am trying to find a bearing replacement that will not leak oil through the bearing .

These bearings look like they could be the answer . Looks like they have a rubber seal around inner diameter where the axle passes through . I will check them out in the near future . Thanks !

Thanks Offroader for your comments ! I liked the term " stress test " reminded me of my medical stress test for my heart . A resting heart or an idling engine are not very useful functional tests . I don't spend all my rides going from 0 to 30 mph at WOT , but I did experience thermal shutdown...

This is sure to cause some controversy ! First my bike : Beach cruiser type frame 24 " x 2.5 " wheels H 3540 with cooling fins , battery 18 x 12 18650 pf cells , controller Lyn 18 FET 100amp . At wot 6000 watt max output . I ride on flat streets in Sacramento . If I take off at wot ...

I am going to use soybean oil in my 3540 motor . Safeway vegetable oil. $5 for two quarts. This is the oil used in high power transformers. Tested all over the world . No toxic (food grade). In case it leaks will do no harm to pets or people ! Put some in the freezer it did not freeze solid. Had...

Wow ! What fun , some REAL TEST data . Overall made me feel good about my newly made 18s 6p 18650pf battery. The differences I see between the Tesla cells and pf's are mostly explained by the 3.4 ah and 2.9 ah ratings , of the cells . Panasonic cells are good .

Pedigo's battery recall. Pedigo is recalling 5000 battery packs , after some of the batteries in the pack shorted causing fire events . Unamed Chinese manufacturer. They will source batteries from Sanyo in the future. Good old Chinese batteries again.

Thanks again ! You are the MAN !

Is it a good idea to set the balancing voltage of the BMS at 4.1 volts ? Will this allow the max charge to be 4.1 volts , thereby charging the cells to 90% and extending battery life.New Panasonic 18650pf cells 18s12p 66.6 volts. Or go for multi chargers the hobby guys use ? Thanks ES source of...

Nissan, A123 ? Nissan in class action suit over bad batteries in Leaf. No way ! Panasonic and Tesla . I hate malfunctions ! Own 8 bad 38140's out of a 40 cell pack, at 30 cycles. "Jake it's China Town" . Rising Sun or Korea batteries ONLY !
