Battery Question

Fetch

Hi Guys,
Im trying to find something out...
I am aware that the voltage of a battery will effect RoF and that mHa will effect the amount of charge the battery has but what im wondering is does an increased voltage mean an increased draw on battery power?

i.e. will a 9.6v 1700mHa run out of power faster than an 8.4v 1700mHa or will they run for more or less the same duration?

Thanks

interesting question, NakedDex should be able to answer this concisevely but i'd imagine the 9.6v would last just as long in terms of the number of shots you would get out of it

Milliamp Hours (MaH) and Voltage are weird as far as I remember from school.

Basically the easiest way to understand it is to view voltage as the volume of energy that is released and the MaH is total capacity.

Like a bucket of water with a hole in it. the size of the bucket is the MaH capacity, the voltage is the siize of the hole. Fill the bucket with water (electricial energy) and it will flow out through the hole at a rate determined by the size of the hole.

Larger hole, more energy flow. Smaller hole, less energy flow. Bigger bucket, more total energy, smaller bucket less total energy.

By extension. Small bucket with the same size hole as a large bucket will not provide the water flow as long as the larger bucket.

I hope this helps.

Logic dictates that (and I'm open to any correction of course)

9,6V = faster ROF, assuming the rest of the AEG is left as is (same spring/GB/etc.)

but faster ROF really means "same number of shots in shorter space of time"

therefore, if you shoot same amount of BBs in same time interval (say, one day of skirmishing) = same duration

therefore, if you shoot more BBs (due to higher ROF) in same time interval = shorter duration



Now, anyone want to enlighten me about Li-Po? I'm seriously considering moving to those for my SIG 552 due to size (v.tight room for a Nicd/Nimh mini-type, and no more to be had without "hackery"), but I've got concerns over the need to heavily upgrade internals (same goes for Galaxy MP7, incidentally).

ambro: LiPo's are a whole different ball game, haven't tried them out yet, but im going to do a whole lot more research before i do.

main problem is that you've got a choice between 7.4v and 11.1v, not a nice medium like 9.6 or something, so going up to 11.1v is going to considerably increase the rate of fire and also runs the risk of burning out the trigger contacts

if you do try lipo you'll need a lipo specific charger and such too

Yeah, I know about new charger and stuff. I don't want to derail Fetch's thread so I'll leave that Li-Po stuff aside in here, and start a new thread
