UPP Official U004 Ebike Battery 36V 48V 52V 72V 20AH 24AH 28.8AH Long Range Triangle Battery with Charger for Ebike 0-3000W Motor (2-5 Days delivery)

I have had this battery for almost 9 months now and have been using it as a secondary battery. I have had 0 issues with the battery beside the maximum charge voltage dropping by about 1 volt as of the time of writing this, which is to be expected for cheaper batteries. The range and performance haven't changed much at all because of it. I have put in about 1000 miles on my bike (probably about 450 miles or so miles only using this battery) so the battery is holding up relatively well considering the cells are not name brand. I would recommend this battery to anyone building or upgrading a bike on a budget.

I have purchased 3 and all working perfectly!

I added this to a 2023 Ariel rider 52V w/ 20 AH battery, so I purchased the 52V Uppbattery to match each other. I used a spark cycle works battery blender, just in case. Everything was plug and play, super easy to install. Now I can go 30+ miles, all throttle, with no torque loss and still have 1/2 the battery left, on average. I have probably put 300 miles on the bike since installing the battery. No observed issues whatsoever.

It performs as desired. Please note that this one 52v 20ah battery is heavy. It will throw off your ride balance a bit but you should adjust quickly. Overall, I like itUPDATE:one year after I bought it to the day, the battery reads 3.14 volts. I have reached out to the company to see what they can do to help me.

Wrong discharge cable provided (Alexander) but It was an easy fix to get an Alexander/xt60 conversion cable connector and a 6” xt60 extension cable for the controller from Amazon for under $20 which came in two days. Test drove bike today and got 21 miles range on highest power pedaling with over 50% remaining when finished.

I replaced the original battery on my 2016 RadPower Bikes RadRover with this 48/52v 20AH battery and couldn't be happier. Once I removed the three bolts securing the battery holder for the old battery, I was able to unplug and remove the old harness. The new battery just barely fit inside the frame where it is now securely held.in place using the supplied velcro straps.In order to connect the battery to the RadRover's controller, I had to purchase a ten dollar battery adapter cable from Bolton eBikes. After soldering the adapter to the connector that ships with the battery, I was able to plug it in and go for my first ride.Fully charged, I get 2-3X the range of the stock RadRover battery. I am able to ride for long distances in pedal assist mode '5' if I like. The charging process takes a bit longer using the supplied charger, but that's to be expected given the significant increase in capacity.I'm happy that I purchased this battery and wish that I had done so years ago as my bike has significantly longer range now. I no longer return he.from my standard ride with a fully depleted battery.

I read the other reviews and want the battery they paid for. The one I paid for appears to me to be an old dying battery. Or a new battery with old dying cells. After paying over $350 for a battery I want what I paid for.Just got it a couple weeks ago. The bike is ridden 3x a week about 10 miles. On the weekends I take it out and explore the local beach towns. I'm looking for at least 20 miles out of this battery. Today was the first day I really got to test it out. It really never got the bike up to full speed. on standard 48v/13ahr battery I got 31 mph out of it. This battery only gets 29 mph for a very short distance, maybe 1-2 miles, then slips down to 26ish mph. But today at the 4 mile mark the power dropped about 20%, torque drop was very noticeable. I'm in Florida so it's really flat here. Any incline dropped the speed to about 16-20mph at the 4 mile mark. I know the controller limits top speed but this battery was dying out before that governor was triggered. also to note at this mark the battery was registering only a 50% charge... The display registered 60%. But it also dropped from 100% to 80% in the first half mile. I kept going thinking at 25mph I should get at least my 20 miles out of it. Nope. And yes, I'm an idiot because at the 16 mile mark.... when the battery died, still registering 20-50% charge I had 6 miles to get back home. Not to cry like a *** but this is an Aostirmotor S07 and stripped down its 90lbs. regardless, not happy with the purchase. I felt like as soon as I got out it was already dying, losing torque, speed, distance. I really think this battery was made from refurbished cells. I would be willing to try a replacement, possibly I just got the apple with a worm, but if that one acted like this one I would stay away from this company. I mean really, my dying factory battery from Aorstirmotor was only a 48/13 and dying, noticeably, but still performed top speed better, but it losing distance. If I kept it at 15mph I still get the 13 mile range which is 3 miles less than this brand new 48/20 battery at close to the same speeds... I mean come on. Now I see that there is hoops to go through to return it. Not just drop it off and have a new one sent. I'll update this review hopefully after the exchange. Like I said before, I'm not looking for something for free... Just what I paid for.

On (1) pedal assists and pedaling 95% of the way, the battery got me 33 miles in 2.5 hours before It ran out of power. For my money it’s worth it, that’s a lot of savings on gas by riding a bike on a daily…
