ohms law question

[Simon G]

when calculating what battery to use is it best to have as much room to play with as possible or be as close to what is needed as possible?

for example with a 0.17 build gives me close to 25 amps based on 4.2volts so would using a samsung 25r be a no no and would be best using samsung 20s (based on using two batteries not one)

Are you talking about a mech? If not then the resistance isn't important, the wattage is. ... and if you have 2 batteries in a regulated mod then you can half the amp draw once you've calculated it properly.

yeah was talking about a mech or unregulated

The harder you push your battery the more sag you will get.

yeah thought that would be the case. Just wondering what to get now. I like the look of the SQ217 and the Luna but still thinking on going regulated and get a topside dual carbon when it comes out
