John one of the major marketing points of "LI-PO"s was that size for size it had much greater potential (Power) than that of the "NI-MH" and the "NI-CAD".
I use a "LI-PO" in a WSN/TORRO M16 Halftrack primarily because anything else of the same size would have me changing battery's twice as often.
All my 1/8 scale r/c Aircraft have them,
I don't think I have seen an Electric flight powered aircraft use anything else except "LI-PO"s.
They come in all shapes and sizes and when it comes to power to weight ratios the "LI-PO" has everything else beat,
Used sensibly and charged using a bag they are an asset.

I just measured one of my Aircraft "LI-PO"s,
2900 MaH, 11.1 Volt, 3s, 9.5 Cms long X 3.5 Cms wide X 2.5 Cms deep.
It lasts forever and recharges in under an hour !!
Shaun.

I will probably have a look into lipos once I get set up with this battery and a suitable charger

Sorry Shaun but Li-ion batteries don't suffer memory effects. It's actually better to charge them more often rather than almost fully discharging them.

From the battery university site. "There is no memory and the battery does not need periodic full discharge cycles to prolong life."

Tom any confusion or downright inaccuracy I have put forward I withdraw without reservation,
Although the literature dose ascribe a memory to it but it is not rated as relevant.
However It might be worth making an observation or two about "LI-ON Battery's,
"Samsung" Lost a fortune on the "LI-ON" battery's in their Mobile which had to be withdrawn when they caught fire and the buyers were subsequently refunded and "Boeing" spent a fortune in damages and modifications to their "Dreamliner" Aircraft when the "LI-ON" Battery's in the tail section of various airframes failed and caught fire, Just saying

Edit.

Wasn't that caused by manufacturing faults rather than any memory effect.

I honestly don't know Tom, But given that the science behind the "LI-ON" battery is over a hundred years old I would have hoped that the complexities of Dis-Charging and Charging them would be well known by now,

than a lipo but I have found some of a compact size and of a decent mah which look a good choice, do they
need charging in a bag or in any special way for safety.

Hi John, See if this helps any



I haven't had any trouble charging the li-ion, but I rarely use them. I've been using li-po for about two years and I just follow the basic safety rules (follow them religiously) and I've never had a single problem. Hope that helps.

Thanks for that gary, very helpfull

regards john.
