This was full of 65 new SAMSUNG ICR1865026J(2600mAh Purple 5×13) 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.

Iβm all smiles. Let me say this, it has been a journey putting together this DIY ebike. After waiting almost (2) months for this battery to make it to my doorstep and on to my bike. The wait is FINALLY over. I charged my JOYISI battery up upon arrival. Did a few finishing touches to my brakes and put my camping backpack together. Now it was time for the moment of truth. Iβve watched 10,000 bikepacking videos and bike camping videos now, itβs my time? I just rode around the neighborhood for a few hours and fell in love with my setup. With my JOYISI battery being the biggest edition. I recommend JOYISI because of the quality of their product and their commitment to customer service. I mean, this company answered every question I had and fast. And they are giving me a discount for being patient. I plan on doing plenty of more ebike builds and JOYISI will be my go to ?

The battery is very good but it is easy to think there was no installation plate included with order. It is already attached to battery and requires a bit of force and understanding to dislodge. Once figured out, it is easy and very secure but it is tricky to do at first. After showing Joyisi a picture of the battery they sent me, they quickly responded with pictures depicting the battery with plate on and also off. This was enough to show what to do to dislodge plate from battery and re-secure. Very responsive company and outstanding customer service π

Upgraded from stock 48v to this 52v battery and been running great for over three months. Enough power for a 25 mile round trip solo commute with a 1000W mid drive. On weekends, two up riding yields around 20 miles with semi-aggressive riding. Will buy again when ready to go dual battery or want a spare.

52v 19.2 ah Tesla cell is a great battery. This BBSHD 1000w mid drive motor equipped bike has hit a top speed of 41mph on flat Panama City Beach, FL roads. I use this bike as a commuter and while I don’t max it out all the time, I do push it. My AVERAGE speed I’d say is 18-20mph hitting 30- to 35mph in stretches. This battery has given me 44, 41, and 42 miles on it’s first three charges respectively and If I slowed down a bit and stayed under 15mph, it probably would give me close to 60 miles. Couldn’t be happier with quality of this battery, it’s price point, and the excellent customer service I received from the seller. He answered all my questions promptly and professionally. I will certainly purchase again when the time comes.

Dual Battery setup, no problems! Love this battery so much I bought 2! I have so many different applications for this that it’s insane. It’s even a power bank at one point.

Came with a much higher quality charger than the Unitpackpower battery I bought for my wifeβs e-bike. 3Amps vs 2Amps and the charger is aluminum with a cooling fan the keeps it cool to the touch vs a plastic body that gets over 155f (checked with a temp gun because it was concerning hot to the touch). The charging plug is also much easier to remove when using the joyisi charger. The UnitPackPower one is very difficult to remove, to the point where Iβm genuinely concerned it will rip the port right off the unit if not handled correctly. Considering my interactions with Joyisi customer service vs UPP I can say without a doubt Joyisi is going to be the better option to deal with if you have an issue.
