New Em3ev 50v Electric Bicycle Battery

I ordered a new 50v electric bicycle battery model INR18650-20R. I got it over a week ago and have put over 100 miles on the bike since I got it so I could give a decent review. It uses very high power cells the 18650-20R with NCA type cell, 10C rated with Capacity of approximately 1.95Ah. The electric bicycle battery pack is 11.7ah. Compared to my lifepo4 10ah pack I like it a lot better but there is some major difference in the lipo and lifepo battery’s. This new battery acts more like a regular battery meaning it slowly loses its charge unlike the lifepo4 that seems to go from full charge to dead in a few minutes, when I first charged the battery I was amazed at the speed and tourque the first few miles, on a stretch I usually do around 26.7 to 27.1 mph I was doing 29.3 mph, considerable difference, climbing hills there is a big difference also. Still have to pedal assist up the big mountain but with half the energy I had to use with the lifepo4 battery. Another awesome thing about the battery is it is considerably lighter than my lifpo4 10ah battery which is nice when I carry my e-bike up the stairs, the battery comes with a bag that fits in the frame that works for all their frame battery’s. They also make a 50v 25ah battery pack that fits in the same bag, the battery set in the triangle makes a huge difference on the handling of your motorized bicycle here is a link the em3ev battery’s. http://em3ev.com/store/index.php?route=product/category&path=35 I emailed back and forth with paul the owner many times before I purchased the battery, top notch and great customer service, the only drawback I can find with the battery is the bag works like a big sail so a cross wind will catch you off guard, I am making a new leather bag the size of the battery at this time which as you can see in the picture is a lot smaller then the bag it is in in and should fix the wind problem. Any questions you may have ask away, if I cannot answer them I will get an answer from paul

thank you motor motortriker, wait till you see it with the battery bag i am making for it, i am a good leather craftsman and always did one color finishes, this one has color in it to match the bike and so far looking good, should be done with it in a week or so and will post pictures,
em3ev 25ah pack weighs about the same as a 15ah lifepo4 easy rider, if i ever move back to the states i will definitely have one, on an island that is 28 miles long and 9 miles wide i didn't need all those amps plus living on second floor of a condo the darn motorized bicycle is heavy enough carrying up and down the stairs.

the shipping was very reasonable and it got here fast after being shipped, i am very satisfied, my electric bicycle likes them to

the charger I got with it you can charge at 100% 90% or 50%. if you charge at 90% they are supposed to last twice as long which makes them comparable to a lifepo4 however of course I charge at 100% because I want all my power. the difference in size and weight is amazing

dan the difference in the sla and the lifepo4 on an electric bicycle is night and day, you are going to be very happy, i still love my lifepo4 battery's. i mainly like this one the way it fits in the frame, attached is a picture of the case i am making for it and you can see how small it is to, the bag that came with it make it look huge and way to big for the battery. my grandson was great helping me with the picture, thank morgan!
the white around the edge is a bicycle chain, made a great border

thanks dan, this was my first attempt at coloring the leather, not done yet but i think it will be really nice, kids and grandkids flew in today so won't finish till they go back to the states in 10 days but thats ok. i may mount the new bag with battery at the bottom of the triangle for a lower weight, havn't decided yet. i designed it to put top or bottom

i have had family visiting the island for the last few weeks and now that they have headed home i am able to work on my bike. i decided to try something different and that is mount the battery as low as possible so i am not top heavy. just took for a test drive and wow what a difference especially when turning sharp turns, very happy with the results, i knew if i mounted this way everything will hit the battery, like puddles and dirt so i lined the inside of the leather with silicone and also i will probably have to clean the outside weekly which is fine. now it is time to fine tune, i will be able to shorten wires and make every thing nice and neat. i just slapped together to test ride and i am very excited. attached is a picture to give you an idea what i am doing

i just told em3ev which connectors my magic pie had on it and they sent it with the correct plugs, i like the thumb throttle best. i like the lipepo4 batterys however i wanted one that i could mount in the triangle of the bike which is pretty small on my mountain bike and also something lighter because i have to carry the bike up the stairs and the lipo matched what i needed. i want an electra,. i think they are the nicest cruiser out their, get one with front shocks, i have a trek pure which is like the electra but it is not an electra lol
