Battery-sub ohm-is this one ok?

I have two Sony 30amps on the way. Can someone tell me the amp limit on the battery below and is it ok for some sub ohm builds, how low?

That is a 10A battery, so I wouldn't suggest going under 0.8Ω.

I agree with Scarey. It isn't the mAh you need to worry about with sub-ohm, it is the current carrying capacity of the battery, and each brand and size is different, so you need to check the mfr. specs on it before using it sub-ohm, and don't go over 75% of the max rating. For example, at 4.0 v (the 3.7v battery actually charges to 4.2v), a 0.25 ohm coil requires 16 amps. The 10 amp battery you pictured is very insufficient for that low a coil. You need to put the volts of your battery and the ohms of your coil into an Ohm's Law calculator BEFORE FIRING IT to make sure it is safe or you may wind up with a severe injury or fire.
