But did you notice they say a cell will show about 3.2v for 90% of it's capasity but they recommend not normally exceeding 80% of capasity? This is basicly what I was saying. It is not adviseable to graw down lifepo4 cells to 2.0v or even 2.5v. In fact if they hold 3.2 for 90% of capasity they shouldn't even be drawn down past 3.2v. But we all know that under a load the voltage is going to drop below 3.2v. It's hard to figure but I am guessing they are talking about voltage at rest again. Which is a little stupid when talking about a draw down capasity.
