Joyisi Ebike Battery 48V 13AH / 36V 15AH Lithium ion Battery with Charger, USB Port, Electric Bike Battery for 1000W / 500W Bike Motor (Black)

This was full of 65 new SAMSUNG ICR1865026J(2600mAh Purple 5x13) cells, and they look and test authentic! Pack and mount weight 8.9lbs, and has a good quality BMS(BMC13S30A). Unintentionally tested its short circuit capabilities and they work great lol(takes a minute for it to reset, but expected, works on both charge and discharge side... don't ask how i know). Running this on my 1000W rig, i get a solid 16-18 miles out of it before I start looking for somewhere to plug it in. Mount took a bit of modification to work it onto my bike, but there is also a third mounting hole under the bracket. I drilled a few rivnut into the frame and it is SOLID mounted.The only issue I have is it keeps the power on the bike while charging, which keeps my headlight on even when the switch is off. Not a fan of the XLR connector for the charger, but whatever.Been on this for about a month and not disappointed so far.EDIT: well as with the past battery, I ended up taking out the cheap charge plug and replaced it with an Anderson connector. the battery life is still phenomenal though. got just over 20m the other day.

The only reason I don t give it 5 stars is bc it comes with no instructions at all,but once you figure it out,it works very good,I am using it to power a 1000W ebike motor and it works flawlessly.UPDATE: I received the electronic version of instructions,BUT customer service is tops,so I am updating it from 4 now 5 stars.

seems like a good battery; lots of power distance, but not weather proof. Who leaves bike outside or rides in rain? bad ideaalso, doesn't fit bottle cage points. well, it does, but unless they are mounted high, like near the top of the tube, about 9" from the top, the position will be wrong

This is powering my custom 1000watt 48v ebike. I specifically chose this brand because of customer support. It's been great too. It comes with a decent length of power cord with NO connectors attached. Which I understand. My controller has bullet style connectors with 12gauge wires. The battery power cable looks to be 10 gauge. Nobody in my area had bullet style connectors in 10 gauge. I emailed the seller & they very promptly responded and offered me whatever connectors I needed for free! They were extremely helpful with any questions I had. The battery has been performing great! I wound up resplicing my controller with common butt style connectors and problem solved. But the seller did offer them.

My 1000W Ebike will run about 20 miles on a full charge on flat ground, full throttle at 28mph. If I go slower (~20mph) and pedal to help it will push to ~40-50. Exactly what I expected and needed!

First impression of this item out of the box was to how durable and strong it is! The battery has a sleek finish with no imperfections along the body. Included is a button in which you can plus that helps show the battery life remaining. Charging is quite simple. On top of all that, probably the most thoughtful feature, it includes a usb charger! You are able to charge your phone when taking long bike rides in dire situations! This battery is truly worth the money!

Solid build. Great water bottle bracket. Had to drill through my frame, because of too low a placement on my Specialized. So far long life, Still on 1st charge after 3 days of use. Keep you posted if lifetime does not live expectations. 5 star unit. Updated: Near a full year of use, 1500km and no loss of power. Flawless so far.

I needed a battery for a custom-built mid-drive conversion. After searching all over for a battery that was a good mix of volts, price and amp-hours, I decided this was the one for me. The packaging was solid and shipped relatively quickly via ground (never air for lithium batteries). The instructions were as expected, which is to say not great, but by this point I knew what I needed to do anyhow.One thing I wasn't expecting was the need to butt-splice the included Anderson connectors to the battery itself. I suppose there are other connectors out there where it wouldn't make sense to mass produce all the variables but still would have been good to note that somewhere. Comes with a charger, keys to lock it to the cradle and a cradle. The cradle design didn't lend itself to the specific frame that I have so I needed to install 2 more rivnuts to my frame for the battery to install but it feels solid, we'll see how it holds up over time!
