3.7 volt 2200mah. so 2 cells would give me 7.4 volts thoughts?

Nice where did you find those?

_BEN_ · 07-14-2007, 10:17 AM

Can those handle high current applications? Looks like they are mostly used for personal electronics. Good for a RX pack for sure if you can charge them.

They run the A123 cells. Made for high drain apps.

The cells you found might be a crap shoot.

Skol?

"LIGHT, CONVIVIAL, REFRESHING."

I want heafty, hard to drink, and makes me thirsty for another.

rockwerks · 07-15-2007, 08:24 AM

So no one has a clue on the batteries?

i'm no batteryologist, but if you want to go li-ion, i'd go with something that is specific to rc, such as the link above.

Max discharge on the E-bay ones is 1.5C. Thats 3.3 amps.......

JohnRobHolmes · 07-15-2007, 08:53 AM

those cells are 1.5C discharge, which is a whopping 3.3 amps.

edit: I type too slow!

What kind of discharge rate do I need for brushed mamaba max or novak use?

JohnRobHolmes · 07-15-2007, 09:18 AM

At least 15 amps continuous IMO, but higher voltages and lower wind motors will need higher amp draw capabilities. Stalling a brushed motor is when you really start to see the amp draw increase.

Good for 40 amps, should have you covered

midoco · 08-03-2007, 12:21 PM

standard li-ions are not good for RC apps. They don't put out much current for starters. They are generally 3.6V nominal and 4.1 charged. ABC123 cells are a newer chemistry and completely different. I don't have much experience with them, but I have heard great things. I will stick with lipos. I've been using them for years in my electric planes. btw... I prefer Dualsky packs from www.2dogrc.com
