    great li-po 9v batteries
  

*by M***S on Reviewed in the United Kingdom on 10 April 2020*

I came across these whilst browsing on Amazon. Thought these were a good concept to use with electronic projects.Sometime you just wanna play without locating the small acdc adaptor.They're just like any other li-po, charging does take a while but they do work great.Allowed me to build and test my next project on my breadboard.Being a li-po there's none of that how long have they not been charged.To me they are worth the money. As they came in twos you can use one charge the other. Well in the first instance they come with a cable that lets you charge both from one usb socket.Because they came in twos this was why I liked it.After playing and drained one battery you can use the second whilst recharging the original.Would I buy them again, yes I would.

    Good Batteries but 2 Issues
  

*by M***G on Reviewed in the United Kingdom on 10 February 2021*

What I like:The 4 batteries are sturdy and are of a good build quality.The charging indicator lights are nice and functional.It is very nice that 2 cases are also included.2 duel micro usb charging cables are also included.What I do not like:One of the charging cables is faulty and does not charge the batteries. At first I thought it was the batteries but on further testing it was clear the cable was broken. Very disappointing as its lovely to have them all on charge at the same time using only 2 usb ports.The other annoying thing is that one of the charging indicator lights is different from the others. 3 out of 4 of the batteries have the same red indicator lights, however 1 of the batteries' lights strangely glows very bright whereas the other 3 lights are nicely positioned in the hole that lets the light escape.Over all nice batteries, but faulty cable and strange indicator light.

    Good batteries 8.5V
  

*by C***2 on Reviewed in the United Kingdom on 7 December 2019*

Good batteries, however there is one thing to know. They are not 9V batteries.They show only about 8.5 V when fully charged, and voltage drops during use.
