    Are Scooter LG 36V 4.4AH battery packs good for Ebike?

    I believe one of these would work good for using them in parallel http://www.ebay.com/itm/New-RC-XT-60-Banana-Parallel-Charging-Harness-5-plugs-XT60-Charge-Cable-Lipo-USA/201955146228?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649 would just have to use connector of your choice...

    How do i figure range from collected e-meter 2 data?

    Well as a side note I tested the Schwinn with the 850w DD hub today with the same 36v 18ah pack and the same 2.5 mile one way trip so 5 miles total. On the way into town I used 1.531 ah so total of 55.16wh for 2.5 miles on the way home it used 1.482ah so total of 53.35wh for that 2.5 miles And...

    How do i figure range from collected e-meter 2 data?

    well this is the listing. But doesn't give specs for the BMS http://www.ebay.com/itm/NEW-LG-36V-4-4AH-BATTERY-PACK-18650-EBIKE-VAPE-POWERWALL-BATTERIES-20-CELLS-BMS-/172630688902?hash=item2831974486:g:nKUAAOSwuspY9YNZ

    How do i figure range from collected e-meter 2 data?

    Seems correct. Although I have been charging each SLA battery individually with a 4 port I-max charger. The weaker/older batteries always take more ah to recharge and is also how I know that I currently have a battery about to give up. Might just be me and the way I recharge but it seems SLA...

    How do i figure range from collected e-meter 2 data?

    Exactly. So the variable would be the voltage. I used .616ah on the one way and .855ah on the way home. So I do know how many ah's I used but one could use the generic 36v as the voltage? That would be 36*1.471=31.396wh's so 31.396/5=6.72wh/m correct? But if the average voltage was higher or...

    How do i figure range from collected e-meter 2 data?

    Thank you. That is how I thought it should be figured but I used 39v and got like 24.04wh for the trip in and 33.345wh for the trip home. I thought I was using the correct equation but wanted to be sure. I was taking it fairly easy as another rider was with me on my Schwinn Meridan but the...

    How do i figure range from collected e-meter 2 data?

    OK then 1000mah=1ah so to convert one would simply take 616mah/1000= .616ah That should help the e-bike crowd figure ah from mah. HAHA just having fun. Not trying to hurt any feel goods But yeah the variable would be the voltage to be able to figure wh/mile I should have data logged and then a...

    How do i figure range from collected e-meter 2 data?

    Today I hooked up my E-meter 2 just to check max watts and mah used during a 2.5 mile trip one way. I recorded on the 2.5 miles home also. I am currently using 36v 18ah SLA. It is a Dillenger 350w geared front hub on a Kent monterey Trike with a 7spd rear free wheel. So the 2.5 mile trip on...

    New "TSDZ2 Torque Sensor Central Motor"

    Thank's for the link. That is a good read. Although my trikes are of a different build it was good to see how the recumbent crowd reacted to the TSDZ2. I would like the 48v set up but i'm thinking of leaving the front hub motor on for emergencies so a 36v would be more practical. Also if...

    New "TSDZ2 Torque Sensor Central Motor"

    Oh ok I didn't try that. I wasn't trying to go off topic just trying to figure out what gearing would work well with the TSDZ2 torque sensor and my needs. Or if it would at all be a upgrade from the 350w geared hub in terms off assist ability with my heavily loaded trike or if another 850w DD...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks for the help. I used the gear calculator and to me it seems like the 14-34 and 42 chain ring might be good. The 42 chain ring and a 34 low gear would still be just a little lower than what I have now and the rest would be a more speed then I have now...

    New "TSDZ2 Torque Sensor Central Motor"

    Thank's for the help. After doing some research. I have the Shimano MF-TZ21 thread on free wheel and the is a 14-28 set of sprockets. The only other alternate gears are 13-28 and 14-34. it would be nice if they offered a 13-34. I always pull a toddler buggy and a tool box. So if something...

    New "TSDZ2 Torque Sensor Central Motor"

    I'm seriously considering a tsdz2 for one of my trikes. One trike is a 26" Schwinn Meridian that is a single speed and currently has a 36v DD 850w front hub motor and acts more like a e-scooter than a e-bike while the other trike is a 26" Kent Monterey with a 7 speed shimano and a dillender 36v...

    Controller with adjustable LVC?

    HMMMMM, Lipo's are easy and simple with the proper equipment. I have 2 4port lipo balance charges simply plug the balance leads into the ports and press the button. As far as I know lipo's are still the lightest and highest output batteries made today. I have lipo's that are easily 5 years old...

    Controller with adjustable LVC?

    Yeah I had my trike for almost 2 years. From the data and testing that I have done the max efficiency is at around 35v. And 4s packs are cheap. my controller is good for about 50v. But with the added heat and increased Kv *v the efficiency drops to get the same efficiency I would have to rewind...

    Controller with adjustable LVC?

    Well I would like to stay with 2 packs of the same voltage and mah. Then I wouldn't need anything other than the batteries. My rc experience shows that I can use 2 packs of the same voltage and mah in series or parallel without having to have a bms. I can just make a Y harness and connect the...

    Controller with adjustable LVC?

    Thank's for the link, I will start digging through it. I should have stated that I plan on using 4 packs total 2 series and 2 parallel. The problem is 2 6s packs would be 50.4v fully charged and 44.4v discharged. and 2 4s packs is 33.6v fully charged and 29.6v discharged. But then again 3 3s...

    Controller with adjustable LVC?

    Hello all, I am a newby to this forum and have a few questions. First does anyone make a controller that is adjustable for the LVC? I have a Schwinn meridian with a dd 36v front hub and would like to switch over to lipo batteries and the 4s and 6s are the easiest and cheapest to come by so I...
