<DIV> </DIV>
<DIV>Ironically it was the 4P packs that even today claim by far and wide the best cycle life, of pretty much any other packs used in pattern. </DIV>
<DIV> </DIV>
<DIV>Its my opinion (I am sure many will disagree and thats ok!) that 1P packs will have a much harder time getting as high a cycle life as an equal quality +2p pack will. There is no additional cell to share the load, so when you get a weak cell in a 1p pack its pretty much at the end of its life, where in a multi P pack the other cells in parallel can eat the additional load for a period of time. If you break apart an old TP 5300 4P pack I have seen that one cell in the parallel bank is usually weaker than the rest, yet under load that entire bank still performs quite well.</DIV>
<DIV> </DIV>
<DIV>The new Prolite V2's go back to the same manufacturer as the original Prolites, so I would expect the life of them to be very good. I flew them since July and they are great performers, far outperforming the Extreme's and the original Prolites, I only put 50 flights on them so I cannot tell how they will last, but my voltage under load has only dropped a few tenths from when they were new so I expect lots of life yet.</DIV>
<DIV> </DIV>
<DIV>There will be a 5000 1p variety, or a 5300 2p variety available in the lineup.</DIV>

All are showing <BR>> fairly high resistance values and most were noticeably down on <BR>> power. Shot. Kaput. <BR>> <BR>> Soo.. I've got to go invest in four sets. Tru's lighter <BR>> sets enable me to make weight--but I'm not crazy about the <BR>> durability with some of Orland's experience--although they have <BR>> replaced bad(slightly squishy--puffed would be too strong a <BR>> term) packs under warranty. I don't know how their larger <BR>> and higher rated packs hold up and they 'only' put me over a <BR>> couple oz. Price is pretty good.<BR>> <BR>> The older Tanics I had actually held up the best over time--but <BR>> the newer ones have not--and fairly expensive--but I drive by <BR>> 'em twice a day and wave. I had a set of Kokam 4800s and <BR>> they didn't hold up well either and I think they have abandoned <BR>> the larger battery market-- were/are expensive. I'm hearing <BR>> Flightpower mentioned often and wonder if they have a battery <BR>> guru that gives pattern guys a break. I never really got <BR>> serious about TP as at one time they had--as far as I was <BR>> concerned--too many cells in their packs--but perhaps it's time <BR>> to re-visit.<BR>> <BR>> We also had some of the original FMA 5000s and they weren't all <BR>> that great either--but may have improved with a new cell vendor.<BR>> <BR>> <BR>> <BR>> So I'm in a bit of a quandary. Any thoughts? This <BR>> should be interesting.<BR>> <BR>> RS<BR>> <BR>> _________________________________________________________________<BR>> See how Windows connects the people, information, and fun that <BR>> are part of your life.<BR>> http://clk.atdmt.com/MRT/go/msnnkwxp1020093175mrt/direct/01/</DIV>
