48V E-Bike Battery 10AH - 50AH Lithium ion / Lifeo4 Battery Pack with 5A Charger,50A BMS for 500W-3000W Motor (48V 10AH)

Initially, I gave this battery a 5-star rating but after only four charges the charger indicates full charge even though it is discharged down to 50 volts!!! I have my voltmeter hooked up right now and it appears to be charging even though the green light is on but still only four charges????! come on. Help me out!!! make me change my 5-star rating back. Update!!!! (09/07/19) I sent in the problem I was having to Btrbattery and was very pleased to find that they are sending me a new charger right away!! It's a good thing too because I was just charging the battery today and the old charger actually started to melt!!! and now it doesn't work at all!! Grrrrrrrr but I', suppose to get the new charger in four days no returns needed on the old charger which is a huge relief cause I hate doing all that mail stuff. I got 40 miles with my 500 watt scooter and was blown away by the power and distance this little package packs!!!! Oringinal batteries were 22ah gel cell 12 volt batteries in series and I only got absolute tops 20 miles and that was with some pushing to make it home! I intend on telling everyone what great service btrbattery has given and am considering getting ten more of these and having a whole fleet of scooters with them just to rent out to people It is so much fun!!!! Will earned 5-star rating is back!

Bought this battery in January27 2018 for my 2000w forca bossman, didn't know what I was getting in to, cause the battery is for a 1500w scooter love it very impressive my range is 30 to 35 miles at full power at 26 to 28 mph I'm am so happy with it and if I was to do 20mph I'll get like 40 to 50 mile range I live in Manhattan ny and I go everywhere and anywhere with no problem and I trust it. it's so reliable doesn't even heat up on me at all so if you have a 48v scooter I really recommended you won't be disappointed,All I'm gonna say this is a great battery.

This battery has performed beautifully exceeding my expectations for several months now powering my 1KW Do-It-Yourself adult trike. I chose the 20ah size from listening to young folks on Endless-Sphere.com forum thinking in theory I should get an approximately thirty mile range. However, in practice because I go slower than they do I can go much farther. My cruising speed being approximately 12-15mph instead of 30+ like them. I don't know for certain what my range is and I've gone the hoped for 30 miles and still had all three LEDs lit indicating that the remaining charge was greater than half full. BtrPower/BtrBattery has proved to be reliable as they quickly responded to inquiries about any issues I had and handled them more than fairly. Highly recommended.

No complaints about the battery. Shipped fast, product seems of good quality, works great on my e-trike. But beware, this is NOT a 48 volt battery; it is a 52 volt battery. Charges to 58.5 volts, and discharges only to 47.5 volts. Fooled me at first, and caused me to be 10 miles from home when the battery cut off. But after recalibrating my battery gauge, the battery is completely worth it and provides me with 40 to 50 miles of power (1000 watt motor). This review is for the 48v, 30 ah model.Edit after one year use: Put 3600 miles on my trike and this battery this year with no problems. Had to charge it every day though...I rode the he.. out of this thing. The battery, worth it. When the time comes it deteriorates, I will find a way to use these folks for a 50ah model.Edit: Now up to 6000 miles and going strong!

Awesome battery. I'll post an update but it seems legit. It's as if the manufacturer knows what they're doing. It's performing better than expected and lasting, well I don't know. I've taken several rides and still haven't had the meter go down yet. Now, only one of my rides was lengthy but did include some steep grades. I'm super impressed with the power of this battery. Pricey but I seem to be getting what I paid for. I'm happy.

the battery just rocks!! i have no issue about it, just great!..one little thing to let the people know when buying it, is that the 48V 20AH battery, which is the one i just bought, it's a 14 Serie battery cells connection, which means, it provides a little more voltage when fully charged, 58,8V and when fully discharged around 45V, it doesn't mean it's not a 48V nominal voltage, it is, but it provides a little more power. Your electric motor, whichever one you have (350W,500W,750W,1000W, etc), if it's 48V, it will perfectly work with this battery, because of the 14 series, actually provides a little extra power for your e-motor, but no problem at all!

I received a LiFePO4 battery instead of the LiPo that I thought it would be. The battery was great, just not what I needed, and I was able to return it for a full refund.

This is a great battery with a few hard to deal with idiosyncrasies. Awesome power storage, very long use over years of service.However, there are no meters that handle this battery accurately. It is a 52volt not 48volt. It will work perfectly with any 48volt motor, but the battery meter won't show an accurate reading. I bought one with an actual volt reading to get around this, the manufacturer is trying to give me a meter setting that will work with this battery. The meter is multi voltage adjustable but no luck yet. If I get it working perfectly I will update this with everything to make my nightmare simple for you.My only other complication, no battery box. However, the 48V 20Ah LiFePO4 fits perfectly into a standard 50 caliber ammo box (really inexpensive at Harbor Freight) with room for wiring and any switches you might want to add. I cut holes for the charge port and power out port. Be sure to use water proof in and output ports and cut snug holes. Also be sure any mounting hardware DOES NOT CONTACT THIS SOFT BATTERY! Protect it!All and all, you will not find another battery as awesome as this one if you can work around these complications. Good luck and have fun!
