Is my setup safe?

I use the Vtc Mini with a Aspire cleito tank. The coil is pre made 0.4 Clapton (40-60W).Battery is Sony VTC5 (green).

My main concern is the battery. Is there some sort of max amps for this using the cleito?

I'm still a newbie. I just "stepped up" to Cleto from Kanger Subtank Mini that only used about 30W. The display of the VTC mini shows the amps and volts, so what is the highest numbers for these, and when should I be aware that somethings wrong with the battery? Just so I can be on the lookout when playing around to find the right wattage and stay safe. The max W from VTC is 75 by the way.

Any better battery suggestions are welcome :)

Just to clear things up. When using a regulated mod, there are two different amps.
  • The amps your mods circuit board sees.
  • The amps being drawn from the battery.
The mods circuit board will protect itself by throttling down the power if you attempt to draw too many amps (as determined by the board, not the battery) or refuse to fire.

However, the amps being drawn by the battery are calculated differently and are independent of the resistance of your coil.
  • The mod itself has no idea if the battery is being stressed too hard or not. And a battery being stressed too hard will have a shortened life and, if stressed hard enough, can vent or worse.
  • You must still select a battery that can handle the current the mod draws without overheating.
The Sony VTC5 is a 20A battery. So as long as you stay under 60 watts you will not be drawing more amps than the battery is rated at. Above 60 watts you will need a 30A cell.

Perfect! :) Just what I was looking for! Can't seem to find "minimum voltage" for the VTC5 anywhere, as the formula from your link requires. Any help? I was able to find this info though, but it dos not say "minimum voltage":
  • Nominal Voltage: 3.6V
  • Discharge End Voltage: 2.5V

The minimum voltage is when the mod indicates that the battery is drained and does not have enough voltage to fire. Most mods will will cease to fire when the battery (any battery) is at 3.2 volts.

If you wanted to test it you could measure the batteries volts with a DMM when your mods battery bar is empty and the mod will not fire.
