Joyisi 48V 20AH Ebike Battery, Lithium Ion Bike Battery with USB Port, 50A BMS Protection Board and Charger for 1500W/1000W/750W/500W Bike Motor

I installed this on a fat ebike build and I weigh 280lbs. This battery will allow me to travel at least 20 miles on a single charge. The straps are great, and are tough. The straps also work great to protect the frame as pictured.

The battery measurements are off by 1/2 in each way due to the straps not included in the specs. non-returnable. beware of the non-return policy which is not stated clearly. very disappointed.

Update, customer service excellent, had small crack on casing, Joyisi sent out new case immediately , bike up to 134 miles on battery, recommend this battery. GregBike up to 400 miles, battery runs strong, durable.

Don't order this battery thinking it will be delivered close to the date listed. I'm sure it will be a fine battery once it makes it to it's destination.

Battery is solid, easy to install...decent life but I only get about a 25 mile range with a 750w engine.

I was worried about purchasing this Triangle style shape battery for my 48v 1000watts beach cruiser bike at first but when it arrive and installed it, it fits perfectly also looks great. I had a dolphin shaped battery prior and was only 48v 10Ah which is very small and didn’t last as long. The power would cut off due to the BMS drawing lots of power when riding fast. With this new battery pack, I don’t have to worry about over load or low batteries any longer on my ride to the beach. It also has USB port to charge my phone and flash light if needed. The best part about this is the power button which other similar product didn’t have for safety disconnect. Over all, it looks and functions awesome. I am planing to build another bike down the line and will be looking forward to using this battery again.

I am impressed with how well these are built!

This product and this company is awesome! I'm using it for my ludicrous BBSHD and it's 50 amp constant discharge rate is perfect. I'm running my motor at 50 amps, and I'm still getting forty miles on a single charge. It's a really great product. It's fits my frame nicely and has all the power I need. I'm an ex-motocross racer, so I like a lot of power. This battery meets the demand. Their customer service has been very helpful, and overall purchasing this battery has been a very rewarding experience. I've already ordered another one from them for my other bike. I strongly recommend this company and this product. I was shocked at this distance I got.
