Battery Longevity

Battery Longevity Reports

I am flying 2 setups.

1. E-Evolution with Plett evo30-10 motor & Schulze ESC Flight Power EVO F3A

   batteries - (2 sets)  app 35 flights on each set. A 3rd set( my first

   pair) from 2007 after app 100 flights began getting warm and down on

   power. No idea of IR as I didn't have a cellpro then.

2. Black Magic VF3 / Axi F3a / Jeti99 Esc True Rc 5000 batts (3 sets) app 40

   flights on each set - a little over 1 year old and still good. IR as I

   remember is under 2.5( don't have actual numbers).

3. for a short 8 flights I had a Pentathlon/Dualski/CCHV85 - used both

   flight power & true RC batteries for those 8 flights. Good power and the

   batteries stayed cool. They were even cool when I picked up the debri <g>

Thunder Power Prolite 5300	195	First flight April 2006. Retired in June of 2008. The A side was coupled with the A side of battery number 2 and is still flying. The B side was given to a friend and is still flying.
Thunder Power Prolite 5300	140	First flight April 2006. Retired in June of 2008. Puffed a cell in the B side due to fault in Hacker C50. The A side was coupled with the a side of Battery 1 and is still flying. The B side is now a 4s4p and was given to a friend.
Thunder Power Prolite 5300	19	This is what I call Battery 1A2A. First flown in June of 2008 and is still flying. I find that if I heat it before flight it works fine for practicing in cool weather.
Thunder Power Prolite 5300	171	First flown in May of 2006. Still flying. Good for practice in cool weather like battery 3 above.
True RC 5000 10C – long	102	First flight Feb. 2008 and still flying. Tops from a cost per flight standpoint.
True RC 5000 10C – short	29	First flight July 2008. Sent back in October and is being replaced. One cell well out of balance almost from the start. Puffing on all flights when hot.

Thunder Power 5000 – 10SX V1	184	Purchased 02/07. Continues to be my strongest battery. Always balanced within .020 after a flight. It's a freak!
Thunder Power 5000 – 10SX V1	102	Purchaed 06/07. This battery was slightly damaged in 07 and should have been disposed...but I couldn't do it! After showing it to a few 'experts', they said fly it. So I put it back in service 6/08. Seems to perform okay in flight but gets a little warm during the charge. Comment from TP on this: "Thank you for the information, we believe you have a cell starting to go bad, it is building up resistance, that is why it is getting warmer. I would monitor this battery closely and as long as it does not get hot or you see a performance loss, it should still be usable."
Thunder Power 5000 – 10SX V1	111	Purchased 07/07. No issues
Thunder Power 5000 – 10SX V2	75	TP Exchange 05/08. No issues
