6.6v LIFE BEC Supply

[PilotPhil]

What capacity rx pack will I need to run the beastx off a LIFE 6.6v supply rather than BEC.

lipos range from 450mah - 3000mah.

will be going in a Rex 550e.

Whatever fits Phil, the capacity is up to you. It just won't last as long, a word of warning though, I got 2 LiFe packs yesterday and they're heavy. 2300Mah

[PilotPhil]

roughly how much Mah will be sucked out of them during a flight?

was considering this

FLP Distribution

but they do 450mah ones for about £6 just doubt will last long.

[jamiem]

I'd bank on around 3-400mah per flight.

[Chris Boughton]

My 600le takes out around 500mah perflight (very hungry),
I personally would look for something around 2000-3000mah

[waveydavey]

The 450mah will be right on the limit of one flight per pack. Aim bigger Phil

[PilotPhil]

ill get the 2150 size, should be plenty as I wont be hard flying for ages lol.

im crapping my first flight

Might be worth putting a low voltage alarm on the battery. An average of 5 amps is a lot.

hyperion 2100 fits lovely under the battery tray,mines velcro'd in place with one of the main flight pack straps round it too.you will probably only use up to 200mah per flight till you can fly like jamiem,which will be a long way off yet

[PilotPhil]

going to buy a couple of these, one pack should do 2 flights so will easy see me through a day. plus keep weight down.

With LiFe packs when that goes off it will probably be too late. It is one of the features / draw back to these batteries, they give there capacity at a very constant voltage and then the output drops very quickly. I far as I know the only way to use these is to have a flight then re-charge to see how much has been used and do the calculation on number of flights.

Thought you wanted life not lipo...you will need a reg with lipo as it will be 8.4v fully charged!

Which servo's are you wanting to run at 8.4 volts?

[waveydavey]

Phil, I think you're missing the point. You asked about LiFe not LiPo. I wouldn't run lipo unregulated and those packs you're pointing at are too small to be any use to anyone I'm afraid. You can use them but you'll get one flight or so.
