72V 48V 52V 28.8Ah 24Ah 20Ah Lithium Battery for Bafang Voilamart AW Ancheer Electric Bikes - Fast 2-5 Day Delivery with Charger & BMS Board - Perfect for Commuting, Mountain Biking and Long Distance Rides

I live in ohio with lots of hills and go over lot's of potholes and get a little over 30 miles of range with one charge going 20 to 30 mph the whole time. It takes about 5 to 6 hours to charge all the way up with a 4A charger depending if i let it die completely or not. It takes less then a dollar to charge!! I try to leave it at the lowest of 30% to keep the battery in very good condition. Some people say the plastic breaks easy but it doesn't, it depends if you strap it on the bike properly or not if it'll start to break. You don't want a lot of sagging in your straps they need to be tight and straight. I did a great job putting it together and it hasn't broken a bit. I Highly suggest this battery.I selected this battery as a balance between capacity and performance vs price for my Mongoose Hitch ebike conversion (Luna/Bafang BBSHD kit, required an XT60 to Anderson adapter to connect the battery to the motor). I've only had it for a week, so I can't comment on durability yet, but the performance is great! I've got a 36 tooth Luna chainwheel and a 11-34 8sp DNP Epoch freewheel, was looking for a compromise between hill climbing capability and reasonable cruising speed. So far, so good. My tests on moderate hills in the bluff country of SE MN have been very satisfying, the battery provides enough punch to comfortably climb all of the hills I have encountered at good speed. I tend not to overstress things too much and use lower gears when appropriate. I went up a steep gravel road , ~1/4 mile ascent, in the Zumbro River Valley in 4th gear with pedal assist consuming 1000W at 10-13 mph in the steepest section, pedaling easily at ~90 RPM. I could have gone faster using the throttle to unleash up to 1500W. Also, I still had 3 lower gears I could resort to if needed, so I felt that the bike could handle a lot more yet. It will get its chance soon in CO and NM! In terms of range: I had extrapolated a range of 54 miles to get down to 20% battery capacity (45.4V) based on observed voltage drops on a couple of 13-17 mile rides, using various assist settings and the throttle (which enabled a top speed of over 35 mph drawing 1500W! I can't pedal fast enough to help out with that, it has to be way more than 120 RPM. My limit of effective pedaling is ~25mph, which seems reasonable to me.) Then an actual measurement: I accumulated mileage of 52.9 miles on one charge -- and the battery was still at 49.1V (~40%) according to my DPC-18 display reading, the battery gauge said 50%. I was mostly using pedal assist in the 200-500W range, with occasional use of the throttle for a little boost going up hills or measuring wide open top speed (did this a couple of times). On relatively level terrain with no wind I consistently ride 20-25 mph in 8th gear, pedaling comfortably with an intensity that my 68 year old body can maintain essentially indefinitely. The bike fully equipped with battery weighs 71.4 lbs., the battery contributed 13.4 lbs. of this. I weigh around 180. This battery with the BBSHD is performing as good or better than I had hoped, I am so far very happy with it! We'll see how it holds up, long term.Seems to be good so far. Came packaged very well and the case seems very sturdy. Takes about 9 hours to fully charge from empty to full using the 2 amp charger. It charges to 84.3 volts. My controller cannot recognize it above 83.9 volts for a 72v battery.The display would come on and everything but had a dead throttle and walk function would not work either. I just left the display on until it drained to 83.9v and everything works as it should. For my particular controller on setting 2 I get about 100 miles of range cruising at 26mph with no pedal assist (throttle only) Am very pleased so far.I got a 2000w direct drive motor with a 40 amp controller.Love the built in connector socket and power switch. Has battery level indicator but I don’t use it. Powerful battery! My ebike will do 39 on level ground in tuck position!I use a dorado reention 52v 18ah battery.That gets me about 30 miles per charge going roughly 28-35 mph.This battery gets me about 60 miles going 28-38 mph. Takes 6.5 hours to charge using 4a charger.First these battery cases are thick yet slim. Nice metal and ports are sturdy. the charger has a fan in it. Its worth around 30-40$ so good deal there. Customer Service is Outstanding. I bought 3 of these for my small cycle shop and had them in storage for a year. I left the batteries dead for a year and left them on the charger. 100% still new. 100% outstanding endurance. Great BMS to allow this. Will be buying more soon.A couple things that could make this battery better would be a key switch and permanent mounting options.That being said I've had zero problems with this battery. Was able to slot in the leads from my EMC and taped them up just to make sure everything was secure. I have a very large frame so I'm still able to fit a water bottle under it even with the electronics mounted to the post.I've ridden over 13 miles on one charge and the battery meter says I'm still around half charge when I get home. Charger is small and light enough I could put it in a saddle bag or on a cargo rack to charge at my destination if I needed.One other complaint is 2-5 day shipping in the title when mine took 6 days to arrive. I live in a modestly large city and get most amazon shipments in 2-3 days so that was kind of a let down.I ordered the battery for a Trek Valencia. After receiving the battery I found it wasn't the best fit for the Bike or how I would be using the bike.I contacted UPP via email was quickly able to return the battery and for a full refund.
