Review: Works great as a replacement for aqua ez pool vacuum - I have an aqua ez pool vacuum and the battery was starting to not hold a charge, when you think it doesn't get sued every day or week after a few years isn't bad. This battery replaced the original perfectly, popped in and charged up right away, been running great ever since.
Review: Worked great in an old Jam Bluetooth speaker - I bought this to replace an "unreplaceable" battery in an old Jam Bluetooth speaker. I had to cut off the jack and splice on the old one since it was different but otherwise it worked perfectly and my old Bluetooth speaker has a new lease on life. With the old battery it only ran for about 20 minutes on a full charge, now it has gone for more than 6 hours and I haven't charged it yet. This is just a simple 2s 18650 Li-ion pack so it should work fine in anything that uses this setup. So far I am very happy with it! It arrived quickly and was exactly what I expected. I would definitely recommend this battery.
