Pswpower US Stock 48V 14.5Ah Hairon The Interior Battery Samsung INR18650-29E ebike Battery fit 48V 750W/ 1000W (USA Warehouse) (AD) PXL-HL-48145-SX

I have used it only twice so far, coupled with a "Voilamart Electric Bicycle Kit 26" Rear Wheel 48V 1000W E-bike Conversion Kit, Cycling Hub Motor with Intelligent Controller and PAS System for Road Bike".Bike reaches up to 31 mph in flat road. With this speed it become slightly unsafe for a bike though; so I ride it continuously at about 22-25 mph, no pedal at all. It easily makes 20 miles and still remaining with some charge, showing only one charge capacity bar after that.Couple of issues so far.The battery holder mounting hole is at the top, usually bike has those holes towards the bottom, not at the top. So I made two whole in the aluminum battery holder and mount it, but I think it would have been better with a steel holder, because the aluminum will break over time with bike vibration. Will see when it breaks, probably then I have to tie it up on the bike frame with some bungee cords.Another improvement is too small wire from the battery holder, had it been slightly longer, like 3-4 feet, it could have avoid to have one extra wire joint. Not a big expense for the manufacturer, but a big help to the user, because then you have to buy some extra thick wire.Another issue is, when I bought, I paid $342, after a week the price has come down to $335.

Ive had this battery for over two years and havent had a single problem. Great choice!

I just got this battery and there are no instructions on how to attach it to your bike. I don't even know what all the functions are for. The wires themselves are so short I can't even use them unless your controller is literally right next to it.After I finally figured out how to connect it to the bike I find the bracket placement is horrible. My water battle holder is more in the lower middle of the bar. The bracket for the battery is at the round end of the pack. (Smaller end) Had the bracket holes been in the middle or at the fat end, I would be able to fit it just fine. The end opposite of the wires fits nicely in the triangle however, the closest I came to connecting it was having the fat part in the triangle. Had it just been reversed it would fit perfectly. So my choices are to send back, get a back rack for bike or duck tape it to the bike.So I ended up getting some Velcro straps and strapping it to the water bottle tube of the bike. I was able to get one screw in so its locked there I just had to secure it in place. I have a 1000 watt motor and the battery worked well with it.Pros:Lock to secure it to bike.
