The Boss Escapes!

More fun! We continued discharges in 5A increments are got up through 7C with a constant 70A discharge. The test cell gave up 9.4Ah in a hair over eight minutes before reaching the 2.1V cutoff. Cell temperature peaked at 52.6ºC (126.7ºF).

Here's a recap of 55A thru 70A:

While we were talking about the way the capacity slowly creeps downward with each increase in load, we heard familiar whining noises from the bosses office. We decided we had to get to a 10C discharge so we could stop delivering food to his office three times a day. Besides - he needs a shower...

The cell isn't rated for a continuous 10C discharge so we took advantage of the option on the 10X CBA amplifier to cycle amplifier power during a test. We cycled power/load in roughly 15 second intervals. First two 'spikes' are 15 seconds load, 15 seconds 'rest'. Then we walked it out to 30 seconds on, 15 off; then 45 seconds on and 30 seconds off. The test ran for nine minutes 50 seconds and the CBA reported a cell capacity of 16.4Ah.

Now..about the bosses office - Febreze or Lysol? Both!
