48V 25Ah Shark Ebike Battery for 500W 750W 1000W 1500W Electric bike Conversion Kit

Great battery. Never let me downWill be getting another.

Nice battery the extra capacity has increased the range of my bike.However a USB socket is shown in the accompanying video but the reality is that it doesn’t have one.

The media could not be loaded. Had this battery for a long time. I have been in 2 crashes and dropped the battery in the CANAL it’s still works have had no issues. The charger broke but was replaced swiftly.

I brought this battery for my ebike. Some important information I brought the 52v 24ah LG cell pack. I have the output amps restricted on the controller through the display to 40a. I am using a 48v motor with this 52v battery (peak watts restricted to 2300w via the 40a limit). All range details here are throttle only no peddling discharged from 100% to ~20%, 1st charge 10 miles, 2nd charge 13 miles, 3rd charge 17 miles, 4th charge 14 miles, 5th charge 18 miles, 6th charge 22 miles. Now I have large amounts of vdroop starting around 55v when in assistance 5 of 9 @ 100% throttle, I will see 2-3v drop on the battery voltage until the throttle is relaised, my display reports 1560w when the vdroop starts at the aforementioned voltage, this issue gets larger the lower the voltage. I have also included photos of my battery voltage, and displays calculation of percent remaining, and the reported remaining capacity via the screen on the battery. As you can see at roughly 51% the pack screen shows 100% and when the and at 21% the pack screen shows 50% charge. I've done the maths in this situation, and it turns out a 48v screen would be showing roughly these percentages. Now it's not a big issue 48v components usually work without issue on 52v batteries but a voltage baised percentage display is going to show the wrong values for a 52v battery. Other than that this battery is large you will need at least an 18" frame to mount the battery and even then your results may vary as I had to modify the mount with a drill and a dremel for my battery to fit.

I needed a new battery as the connection on my original one had stopped connecting, this inevitable has better connections and is a much stronger battery than my previous 17.5, 52v one.I recommend this battery.

It's sheet battery

I upgraded my battery to the 52v 24ah, my bike rides so much better than before I get good mileage out of it and it's sustains it's power for longer.Well recommended.
