Today i will be sharing the pinout/Diagram and experience of the YSD-998 Li-Ion Battery pack you can get on ebay.
its advertised with : Ebay Link Battery type: Rechargeable Li-on battery Input voltage: DC 12.6V Output: DC 12V 6500mA DC 9V 8500mA DC 5V 15000mA Dimensions: 12.5*7.3*2.5CM Weight: 310g
To be honest i was expecting this to be false advertisement but they aren't far off. These are measured fully charged : 12V 5900~ Mah 9V 7900~ Mah 5v 14300~ Mah
as for Durability they are quite alright, but some seem to have less lifespan. i got 6 of these and 2 of them stopped working after aprox 3 months of service (3 hours a day usage~) The rest of them however are still functioning on of them has been powering my Raspberry pie as test for about 5 months now seedboxing.
As for opening them up you will have to drill out the holes as the screws are covered in glue. on the inside you will find alot of glue aswell so be carefull when taking out the ports etc or use the diagram below to wire everything up again.
I am planning to use one of these for a portable but noticed i could not find a Pinout/wirediagram Anywhere. and as i accidently tore apart some of the wires which were covered in glue etc. i thought i would share this info to make it easier to wire it back up.
Hope this helps someone
