Cheap Li-Ions, but are they good?

Here's the link to the Li-Ions

R these any good? If so, what's the highest mAH that you could use in a stock X-Mod?

Sorry, I don't see any cheap Li-Ions or Li-Polys on that site. www.blindbatts.com has Li-Polys for $3. Go check em out.

To answer yout question about mAh, you can use as high a mAh rating as you can find, because mAh only rates the capacity of the battery.

O...I thought those were cheap...oh well, but you said I can use any mAH I can find, so 1100mAH won't fry my FET or anything??

Nope, and it will run for about 30 minutes with a stage 2.

k. but how much better would they be than the 750mAH?

They would only run longer. There is no difference in current.

well....then how long do 750's run?? Murcielago659 said these would only run bout 30 mins. 750's must only go like 15 or 20 then....

These cells are cheaper!!!!!!!!
these are individual lithium cells=

This a battery pack and charger you could probably rig up=

Good find! I'll have to check those out when I finally get some money.

mAh is a measure of battery life. It is litterally “milliAmps * hours”.

So, if you want a battery that can discharge:
500 miliAmps (0.5 Amps) for 1+1/2 hours (3/2 hours),
you just multiply:

500 mA * 3/2 h = 750 mAh

You can also work backwards from this figure. If you have a battery and you want to know how long it will last with a specific current draw:
1,000 mAh with a draw of 2,000 mA (2 Amps)
you just divide:

1,000 mAh / 2,000 mA = 0.5 h (half an hour).

However, the battery may not actually be able to handle a draw of 2 amps; that is another figure entirely. And just because a battery has good run time, that doesn’t mean it can handle good current draw.

What are the stats for maximum and minimum current draw? Anyone know?
