Joyisi 36V 48V 52V Ebike Battery 10Ah/13Ah/15Ah/19Ah Ebike Lithium Battery for 250W 500W 750W 1000W 1600W Electric Bicycles Motor and Bike Motor Conversion Kit

I ordered this to modify my beach cruiser into an electric bike. I use it to ride my bike to the gym, and funny enough there are two uphill portions going there and riding back. After a good workout my legs are toast so I either need to hop off and walk it uphill, or not lift as hard and lose out on the workout (it has no gears so it's a slog).Unfortunately the battery did not fit my bike railing, it's not a regular shaped straight setup so I had to return it. The customer service was friendly and I just received a full refund. When I did receive the product it was in great shape, had all the parts and until I found out it wouldn't fit my purpose it looked like a very simple install process.

I bought this battery to power a 500W 36V front hub conversion kit.Delivery was delayed due to an accident involving a fire in the shipping container, but the Joyisi customer service representative communicated frequently with me about the delay and gave me several options for getting a replacement and compensating me for the delay.The battery itself works well. I had to install it "upside down" on the seat tube because of the specifics of the water bottle cage screw holes. It works and looks fine in this configuration.

The battery is strong, I appreciate the Samsung cells. Mounting is very confusing though. I have four bikes and none of them have the water bottle mounts far enough away from the seat post to mount this battery in the way the exposed mounting points line up. I was ready to mount it upside down before I decided to remove the bottom backing plate and found that you could mount through the heat sink as well. The battery seems too heavy for the two water bottle screws to hold over time, but I imagine that is the case for all these types of batteries. Time will tell.

In my opinion, this is the best ebike battery value on Amazon (as of 8/2020). I looked at a bunch of others that didn't have as many amp hours for the price, or had bad reviews for failed cells and short life.This battery delivers great power to my 1200W ebikeling kit on a 700C bike, and I was able to go about 20 miles in stop and go situations without pedaling at all and still had 30% battery left.

I built an ebike with this battery. Plenty of range and mounted easily into the water bottle threads on my downtube. For the cost, I don't imagine other options would have preformed any better. You will need to supply your own charger, and I would suggest getting one with a circuit that prevents over-charging to preserve the battery.

Have not had ot long but initial impressions are good. Power indicator button is in a poor location but that's what the controller is for. Mounted up nice and solid. It has a good docking connector. Charger does get very warm when charging but I think most do.

I Love The Battery power but it doesn't hold a charge long enough! I'm Getting about 2hours before the first indicator light goes out! I'm scared to ride too long on the second light! Other than that, I Love it!

It's been more than 3 months since I bought this battery. I was a little skeptical at first, I thought it's another one of those knock off batteries from China. But I'm glad I did buy this, I read all the review before buying as I know returning would be too much hassles. I suggest that buyers should read reviews from verified buyers before purchasing especially items more than $300.00.
