Yesterday was again a throwback day, but as well another motivation day.
We had three black outs and every time the cell testing was interrupted and I needed to start over again. On the other hand it motivates me to continue this project to be independent from the public utility.

I run my chargers off a 100ah VRLA lead acid battery that I was able to revive. It is excellent in the event of a blackout. Apparently you can even run an Opus off one, as it has an internal DC-DC converter, however I have not verified this.
TheLiitoKala has an included car socket adapter, so I guess it is definitely made to run of the slightly higher than 12v found in Lead Acid batteries.
Definitely, blackouts are a nightmare for cell testing.
