Well I had some time to move everything from one enclosure to the other enclosure so now I have the two EBC-A20 with the switching power supply now I just have to put some banana power jacks on the back of the enclosure so I can use the switching power output for buck converters

Update on the unbalanced battery packs that I bought from Battery Hookup I got a refund for the 7 battery packs ( out of the 8 of them that I bought minus the shipping cost ) packs that had lost 30% or more of there useful life and there charge/discharge curves look like crap

The transplant from one enclosure to the other enclosure was a success now I just have to have some time to finish up the banana jacks to the 12 volt 8 amp switching power supply to power the XL4015 buck converter with the voltage/current controller with the voltage/current monitoring meters

Update using the eight channel battery testing machine

I bought a case of 100 of these batteries

https://batteryhookup.com/products/c...-batteries-new

I tested a little over half of them milliamperes hours are little bit all over the place

From 1100 to 1190 not exactly the same and few of the milliamperes are there but the voltage/current graph are all over the place so I have marked these cells to keep them together in a project

One note is that they are only rated for 1100 milliamperes hours so they are what they say they are it
If you are planning on using them with a BMS balancing protection the closer you can get the amperage hours to be the better the performance is out of the battery pack will be

Most of the time when you test battery from a batch of them the amperage hours will very close to exactly the same result with these are not like this they vary a quite a bit

Awhile back I mentioned that I have a battery jumping battery pack that the battery when bad and I going to use some lithium batteries instead the sealed battery pack that was in it I am going to use a 30 amp BMS balancing protection board and the bost converter that I also mentioned a while back as well
