I have an small e-bike that runs on 36v 8AH battery. I tried to find a match on Amazon (the size and dimensions).I found BtrPower. Based the reviews and its product line, I though this must be a real professional battery producer. It never bloats its battery ratings like some of the vendors do. Not only it has regular 18650 based battery packs it has new liFePO4 packs with many varieties as well.My unexpected experience started from here after I bought the 36v 8AH battery.Because of the battery charger port is a little short to fit my bike, I decided to add an extension. During the operation, I accidentally metal touched the charger port for less than a second and the charger wire got hot (someone online said this will damage the battery!!! You should be very very careful about it!!!). After installation, I found out the battery did not work. I know I might have done something wrong so that I told customer service what I have done and it might be my false operation that could damage the battery. I ask them, if the battery has fuse in it and can be fixed. To my surprise, the customer service immediately responded with a message "WE WILL TAKE CARE OF YOU". A few days later, I got my new battery. I've never had such a customer service before and never expected such a treatment from any Amazon seller. For anyone who has an e-bike and wants a new battery replacement, TRUST THIS COMNAY. I am not 100% sure about its product quality at this point (I do have the confidence though) but I am 100% sure it will "TAKE CARE OF YOU".

48 V 20 AH worked great for my ebike conversion! I get 30 mph plus in high gear and over 50 mile range in 20 mph gear. Charger works great as well. I am converting my wife's bike and plan to buy another one for her.

I've now built two BBSHD bikes on the 48v20ah battery. The dimensions are not the best to fit in the triangle, but on a small frame, I mounted it in a faux muscle bike seat built on a bike rack. It's heavy, but worth it for the peace of mind on battery safety. I live in MN and low temperature effectiveness is important too. Don't charge when cold, but they will deliver power at lower temps. It seems to deliver enough amps to feed a BBSHD motor.

I got this battery in April. My brother in law, an electrician, hooked it up for me & I charged it up. It must’ve been mostly charged cos it only took an hour to get to full. This battery replaced a 20ah battery and it’s outperformed the old one. After 31 miles it’s showing it’s still 3/4 full. Last battery gave me 25 miles before it showed 3/4 empty. I thought I was buying another 20ah battery but this one is 25ah. Its a little bigger & heavier but I’ve got peace of mind knowing the range will cover my adventuring and get me home again. I’ve got an old sun shade from an old beach chair over the battery pack that’s attached to the rear rack. No real reason to have it but I figured it couldn’t hurt. My last battery lasted 5 years so we’ll see if it blows it away in that department as well.

These batteries are lighter and smaller than the lead acids I was using and charge faster. Supposedly they last more recharges too. That's yet to be seen but was happy enough with one of them that I replaced both my sons equad batteries with them.

Let me start by saying this BTR brand of batteries is the best that I have used in my Ebike builds. I built the schwinn stingray spoiler about a year half ago and was looking for a battery to use, I tried different ones that were pre-built in a case already but nothing came close to the look I wanted, then I came across these batteries when the were on sale here on Amazon so I pulled the trigger and bought one took it to harbor freight tools and found the hardcase that it is in now, I've have to say this is a well built battery, I have the 35 amp hour battery and have ridden to work which is about 28 to 30 miles away from home one way and still have 60 percent charge on the battery when I get there. The trike was built on 5/18/23 for my wife she has a hernia so can't pedal a bike anymore that one has a 30 amp hour battery she hasn't fully tested that battery yet but plans to in the coming week. My bottom line is my schwinn stingray has had that battery for over a year and half and still runs strong with no issues whatsoever, I highly recommend this battery to anyone who is considering purchasing a battery for an ebike, you won't be disappointed.
