    Hub motors on a reverse trike freighter.

    It's a really bad idea to put two brushless motors on one ESC. Does it sort of work? Yes IF both motors are identical, and the load on them is identical. But it's still a really bad idea, plan on failure if you try it, and try to get it on video! ;-) Here is a You Tube video with some...

    JJL's 1500w 48v E-Bike Battery Build

    Range testing completed! The battery has enough power to get me into town, and back, but climbing the big hills on the way home really eats up the power. So 26-28 miles of range with lots of hill climbing, stop and go traffic, and almost no pedaling on my part. I'm taking all the chargers and...

    JJL's 1500w 48v E-Bike Battery Build

    Bike testing updates: Further tests make it seem like my e-bike has the power to go faster than 35mph, but the motor controller is either limited to, or not capable of, putting out significant torque above 35. On a long flat stretch it quickly got to 35, but then the power seemed to evaporate...

    JJL's 1500w 48v E-Bike Battery Build

    Victory! It works! It took WAY longer than I had hoped it would to create all the buss wires and solder on all the 30 AWG fuse wires on to the buss's. That took at least 12 hours, ridiculious! It was my first time and, I was making it up as I went. There are many things that I think...

    JJL's 1500w 48v E-Bike Battery Build

    Progress! I wanted to post the pack configuration here for future reference. (Boring numbers, picture at bottom) I used RePackR.com, it's a 14s 8p battery, the cell list is...

    If a gas engine produces 9.9 hp what motor size would be the equivalent

    As a very vague rule of thumb an electric motor can replace a gasoline motor thats three times the horse power. - Said another way: your electric motor probably needs 1/3 the horse power of the gasoline motor. The big problem I see with making these comparasons is that horse power as...

    JJL's 1500w 48v E-Bike Battery Build

    Thank you for the info on the wire! I don't know how much the surge at start will be, but it's probably significant. I'm going to go for it with the 30ga wire, and I'll have to check on it after a while. Seeing as this is an experiment for me failure is an acceptable option. I'd rather have...

    JJL's 1500w 48v E-Bike Battery Build

    They are "Transylvanian Naked Necks" - A friend dumped them on us as a joke cause she thought they were ugly. So far they are ok chickens, not really sure I'm ready to judge. I've nwvre had a rooster before, but they seem more aggressive than the Bard Roc's (SP?) we had before.

    JJL's 1500w 48v E-Bike Battery Build

    Seems like it took forever to get the correct battery packs shipped to me. The summer weather here in Oregon is quickly coming to a close. - The e-bike project had to be put aside because my wife decided to get some chickens; and I just had to build the a chicken pallace. That's complete now...

    JJL's 1500w 48v E-Bike Battery Build

    Thank you! - So I've switched to a 14s configuration, and I got a few more cells. The ones I ordered still haven't arrived. Well they did arrive but they were tthe wrong batteries! So I returned them, and the correct batteries should be here soon? Maybe Monday. Not sure I want to wait that...

    JJL's 1500w 48v E-Bike Battery Build

    I built a 13s1p test pack and it was awesome to see the wheels spin, but the BMS cut out the power almost immediatly if I tried to run it while riding. I don't know exactly how big a pack will be good, but other off the shelf 1500w 48v packs are 14ah. So I figure 7p with 2000mah cells will be...

    JJL's 1500w 48v E-Bike Battery Build

    What an excellent website! I've already learned so much. You all have helped me avoid some major mistakes already; thank you so much. TLDR: I have a question regarding pack construction. Can I mix Samsung INR18650-20R and INR18650-20Q batteries? - And if this isn't a horrible idea, what type...
