Default Thunderpower Packs

I have asked this question of Thunderpower without a reply so far. Hopefully Chad or someone else with TP experience can help.

I have seen on distributors websites:

a TP5300-5SPL listed at 577 grams, a TP5000-5SPL listed at 603 grams and a TP5000-10SPL listed at 1172 grams.

Can someone confirm the actual weights and what is likely to become the "standard" pattern pack for a while. I don't want to buy into technology that's going to be obsolete tomorrow.

Thanks

G'day Malcolm,

I'm using the new TP5300 5S packs and they weigh in at 595 grams each. Yes they are heavier than specified but are still lighter than many other packs out there.

I can only assume that TP weigh their packs without cables. I have six 5S packs and they all weigh about the same.

It's funny how manufacturers specify weights for their products but the actual weight is something different. For example a Spin 99 is specified to weigh 105 grams but the actual weight is 120 grams...[:@]

Cheers
Jason.

Thanks for that Jason, what I need to know now is what the 5000s weigh and whether both types will stay current.

Malcolm,

The 5s5000 Pro-lite packs are 585 grams minus ends soldered onto them.
My 10s5000 Pro-lite packs are 1165 grams minus ends soldered onto them.

So basically there is a 20 gram saving over the 5300s. I guess the real question is how do both perform and will they continue to make the 5300s available?

Thanks

Hi Malcolm,
I prepared two of the new 10S PLV2's for Niall, the packs you saw at the W/E.
I removed the 4mm inter-connector and soldered instead, was not happy with this connector/soldering for a pletty.
I shortened the leads to 60mm. The negative is really long as they feed it back under the heat shrink to bring the cables out side by side.
I removed 250mm of cable in total, then fitted 5.5mm neu connectors.
The packs now weigh 1144 & 1148 gm ready to fly.

I think it is personal preference. I have flown both and for my plane I like the 5000's. Some like the 5300's as you can move the CG around more as they have a square footprint. Both packs are holding voltage great under load after 100 cycles. I can fly my oldest 5000 and there is no difference in performance compared to my newest 5000.

250mm! did you remove the lump of -ve under the heatshrink and leave it at the other end? I didn't think you and Nial had enough length on your ESC leads to stretch that far?

Incidentally may have found a decent source for carbon and carbon/kevlar will pm you once it arrives.

Hi Malcolm

All my 5300's when prepared as 10s (one + and one - lead on each pack made shorter and soldered together) and using the Hobbycity 4mm red jacket connectors weigh between 1180g and 1190g ready to fly.

I have not used the 5000's, but have seen some numbers and they appear to hold a little more voltage than the 5300's but the 5300's are still stronger than anything we have had in the past, so either way its great power I have chosen to continue using the 5300's as I feel that there is greater pack stability and resistance to abuse of a 2P configuration vs. a 1P configuration, but that is simply my own preference. I think you would be fine with either.

Malcolm,
No, all at same end, TP had a long -ve run in an 's' bend across the front end under the HS. Leads now exit at diagonally opposite front end corners.
Yes 250mm at least removed.
Weights are accurate and factual.

Andrew, great to hear of no of cycles with no decline in performance.
It would seem these are the ideal F3A packs.
