Unit Pack Power Official(2-5 Days Delivery) - 72V / 48V / 52V 28.8Ah / 24Ah / 20Ah Electric Bike Lithinum Battery for Bafang Voilamart AW Ancheer and Other（W/Charger & BMS Board

It has a lot of power and gets a lot of miles. I've been using this battery in my converted e-bike that I built myself. 1500w motor and 35 amp controller on a bike. The package was well-packaged, and there was no evidence of rough handling during transit. The seller even included an anderson to xt60 harness that I could use to connect to my controller. Because I was trying to establish top speed (43mph) and maximum acceleration the first time I charged it, I didn't get very far. I usually get 80 miles per charge running an average speed of 25 mph that takes it to approx 30% remaining after dialing back the power (still able to pull 38 mph when needed) after dialing back% I live in a very flat area, so there are no hills, and my commute has few traffic lights, so I don't have to stop very often. Right now, I'd recommend the battery and the seller, and I'll update this post if it fails before 1000 charge cycles or 3 years, whichever comes first. If at all possible.

When combined with a 1000W 48V rear hub motor, this battery provided me with ridiculous range and speed. I was able to maintain a speed of around 26 mph for the entire 17-mile ride, then return at that speed for another 10 miles before having to slow down to around 18 mph to make it the rest of the way home. I wasn't able to test the maximum possible range while driving at a moderate speed, but I'd guess 50 miles at around 16mph. Anyone who wants range and can fit this battery in their frame should get it. br>br>The battery also appears to have a feature on the charger that stops the charge when it reaches maximum capacity, which was very nice to discover after leaving it plugged in over night. It will charge in about 5 hours, depending on how long you want to wait for a completely full charge that you won't really need. Another interesting fact is that, despite its bulky appearance, the battery actually weighs less than the 1000W motor. Last but not least, for those who are skeptical about the use of velcro straps to keep the battery in place, look at the photos. One night, at about 15 mph, I slammed into a 4 foot tall poll head. This caused me to fly 8 feet over the handlebars like Superman, but after inspecting the bike for damage, I discovered that the battery had not moved and the straps were not even loose. The only thing that was broken was the front wheel, which had been turned into a hard taco shell, and the rear wheel, which had a mysterious bend that rendered them both unrepairable. Leaving me with a fantastic battery but no wheels to ride withbr>: (br>br>So, how do I feel about the battery in the end? br> If it fits, please send it!.

This battery has been great so far. You can't go wrong for the price. To see how much mileage I could get out of the battery, I discharged it completely. I got 54 miles out of it on its first trip using a combination of pedal-assisted and pedal-assisted techniques. Some hills and flats require assistance and throttle. The 48v 20ah battery pack was purchased. I didn't order the 52v because I wasn't sure if my 18 amp controller would be able to handle it. The charger is the only thing that worries me. Because it gets quite hot, I only charge it for about four hours. I'll charge it for 5 hours at a time, then let it cool down for a few minutes before finishing. When the charger gets hot, it also emits an odd odor. It's a two-in-one charger. The stated charger is a 4 amp charger, not a 5 amp charger. It takes approximately 9 minutes if the battery is completely dead. The charging time is 5 hours.

This device is capable of sustaining a charge for an extended period of time. I haven't even depleted it to 99 percent charge; it's still on full charge, perfectly powering the bike. It will reach "maximum capacity" after being charged and discharged three times, according to the instructions. 5 times. It appears that I'll have to take a few long road trips before I can achieve that goal. There are no issues. On my 34-inch screen, I've included a couple of photos of it.

I've driven about 400 miles on it in the last few months. So far, everything seems to be working fine. There were no problems with overheating or charging. The battery is narrow enough to fit under my top tube and out of my way. Because of its large capacity, the battery is quite heavy. br>br>Note on installation: Unless your bike has perfect geometry, the battery will most likely not be attachable on all three sides (as shown in the picture), so you'll have to improvise when installing it. The battery was simply suspended from the top tube in my case. Because the included velcro straps weren't strong enough, I replaced them with some automotive hose clamps, which worked perfectly. br>br>Complaints: br>br> br>1) Because the power switch and charging port are on the top back of the battery, the charging port flap is never closed while biking. In addition, my leg has twice accidentally turned off the battery power switch; I would advise the manufacturer to relocate the switch and port to the top front.

I needed a replacement pack quickly, and despite Amazon's claims that it would take more than a month to arrive, it arrived in three days, exactly as promised. I purchased a 20AH 48V 1000W battery pack. This was purchased to replace a fried 15Ah triangle battery pack purchased from a different vendor. This one is actually a little smaller and weighs about the same as my 15Ah pack, which is nice because my 15Ah pack was in a nylon case. This one is much more appealing to me. It appears to be a lot more long-lasting. I mounted it on a converted Kent 26" mountain bike, which works great and gives me a lot of extra power. My electric motor is supposed to be 1000Watts, but when fully charged, it gives me a little more than 1300Watts, according to the gauge. NICE! My only gripes are that it lacks an on/off switch, as my previous pack did, and the charger is only two volts. 5 amps is a low current. This one takes twice as long to charge as my 15ah battery pack. A 4 amp charger with a fan was included with my 15ah battery. There aren't any fans in this one. Hopefully, it will help the battery last longer, as my 15ah battery only lasted about a year. The only way to find out is to wait. I'll keep you updated if there are any problems.
