    Ebike Triangle frame battery pack.

    Yeah I did, see my thread here https://endless-sphere.com/forums/viewtopic.php?f=14&t=80860 Getting less than 15 ah out of my 20ah pack but the price was right. All in all I am happy with it considering I didn't want to pay a lot for my first ebike setup. It was kind of a novelty to build this...

    Just received a 48V pack from Aliexpress. Did I get boned?

    Did another test today. This time I took it a bit easier on the bike. Was giving it 75%-80% throttle most of the time (around 25 mph). Got to 14.59 ah/45.14 v/28.0 mi before it cutout for the first time. Was able to get it to about 15 ah/43.3 v/29.6 mi before the battery shutoff. I didn't get...

    Just received a 48V pack from Aliexpress. Did I get boned?

    I'm using a Tenergy wattmeter. I rode in to work and back today, which I think was something like 16 miles and 8 or 9 ah? I almost always am going WOT with minimal stopping or traffic lights. It hovers around 30mph when I get to full speed. The pack is usually down to around 48v after that...

    Just received a 48V pack from Aliexpress. Did I get boned?

    Well I ran the battery down as far as I could go and I got about 14ah before the controller started chopping power. Got a little past 14.5ah before the batteries' LVC shut it off completely. Kind of bummed but it only cost me $364 after the refund. I really didn't want to spend too much on my...

    Just received a 48V pack from Aliexpress. Did I get boned?

    Well they gave me a partial refund so I am pretty happy. Going to buy a wattmeter so I can do some testing on the actual capacity of the pack. I have been able to do 16 miles roundtrip to work WOT (around 30-33mph peak) and still have 47.5 volts when I get home. My cheapo battery meter on the...

    Just built my first ebike! What should I upgrade first?

    Thanks for all the suggestions! Probably do tires, a rack or panniers and a bell first. Is this my best option for a torque arm? http://www.amazon.com/Grin-Technologies-Universal-Electric-eBikes/dp/B00K60C67Y Are there any cheaper options that might work for me? Thanks again all!

    Fair enough, lesson learned. Hopefully it doesn't catch fire.

    Just received a 48V pack from Aliexpress. Did I get boned?

    Well I messaged the seller with my concerns the other day but have received radio silence so far. Funny since both of my previous inquires were answered within minutes. Kind of surprised by the response I got to this post to be honest. I was told I confused the pack manufacturer with the cell...

    Just built my first ebike! What should I upgrade first?

    First off I'd like to thank all the contributors to this forum for getting me started! I wanted to keep my first build cheap so I used an old trek mountain bike I have plus the following items: 48V 1000W rear hub kit (Yescom/Xccerries)...

    Wife got an ebike, now I want one. Help please!

    Yeah I've only been researching this a few days, so all the RC LiPo stuff is still a bit overwhelming. I can't seem to find a real noob guide on what I need to get started. From what I find I think I could wire up 6 - 6S 20C 5000mah packs...

    Wife got an ebike, now I want one. Help please!

    Thanks for all replies! I'm glad you all talked me out of the mid-drive, I wasn't looking forward to paying that much money. As far as the battery is concerned, i think I want to stay away from LiPo. I want something a little more idiot-proof, and I don't want to catch my house on fire. I really...

    Wife got an ebike, now I want one. Help please!

    Greetings! As the title states my wife just picked up a used e-bike on craigslist and now I want one for my commute. I'm about 185lbs and my commute is almost completely flat, 16 miles round trip. Was hoping for something that would let me cruise at ~25mph with leisurely pedal input (I don't...
