Here is a website I have ordered from before and the results that they claim are correct from what I have seen from the batteries I have bought from them
BatteryHookUp.com
https://batteryhookup.com/collection...odem-batteries
I have test about 5 battery packs ( out of 15 battery packs I bought) and have had very good results and so far have not found any bad cells
I have also bought these battery packs before on EBay and they are a good source for a battery case that holds 18650 batteries however the batteries that are in them are not very good in respect of life meaning that they are close to the end of life
I have bought some from this company that have the outside case as well but they tell you that some of the cells might be bad and might not be useable ( they might heat up if charging voltage is higher than 4.0 volts if the voltage is kept low and the amperage is 500 milliamperes you can get fairly good results )

I have a project for these battery cells that are in these cases for a solar panel battery pack for emergency battery packs power supply in case of a hurricane and have no electricity for a period of time
I just have to find an enclosure that is water thigh so I can use it outside for outside lighting
One note I am not getting paid for this information supplied for this post I was not given samples for testing of there batteries this information is given for anyone looking for a good source second hand surplus batteries
