Hello Riders!
I have a Surly Big Dummy and a Stoke Monkey in Los Angeles, for commuting, errands and fun rides.
All activity I have been doing already, just slowly!
I am totally a noob in the electric bike world, this is my first.
I have very limited knowledge and have not been studying long; I had no idea there where so many factor involved!
I have decided to purchase a pack already built and was wanting to run this potential purchase past all of you to see if it sounds correct, or if I'm missing something. I'm open to all info.
Headway 36v 20ah battery pack, The cells in that pack are the 38120SE cells (10Ah) that will be wired in parallel to make a 20Ah battery pack.
The 36V20Ah battery specs are:
36V nominal voltage
39.6V actual resting voltage
20Ah of capacity
720Wh of energy
50A continuous, 100A peak capability (1.8kW continuous 3.6kW peak)
Regen capable
18lbs +/- approximate weight
Anderson PowerPole connectors
In the shape of: 2X12X1 = 19" x 6" x 4".
The 36V20Ah comes with an 18A charger.
A bit of info from the dealer:
" miles per gallon and equating them to watt hours per mile, on average the total weigh of rider and bike is divided by 10, this is typically the average watt hours per mil (Wh/mi) that one gets by using just the battery power itself on flat straightaways without any pedal assist. On average, most eBike systems typically use between 20~35Wh/mi. For estimating purposes, if using the Wh/mi on the high end of the scale of 35Wh, take the Wh of the battery, 720Wh (voltage multiplied by the ampere hours), and divide by the Wh/mi number and this will provide you with an approximate of range in miles. 720Wh / 35Wh/mi = approximately 20 miles of range"
I thank you all for the input you give.
Cheers
