Sony vtc 5

[voofvoof206]

I have a sony vtc and i was wondering what the difference is between and amp and a pulse limit. It says it has a 30 amp limit but a 60 amp pulse limit so does this mean i can safely use up to 60 amps as long as I don't overuse it?

Pulse limit is not a "hard" spec. There is no industry wide, accepted standard.

It could be anything and many manufacturers do not publish this spec. Sony doesn't own up to much of anything in fact as they state that the VTC series of batteries were never intended to be sold directly for consumer/end users use. They all were meant for manufacturers to build battery packs and other parts for power tools and such.

The only true specification we can rely on is the continuous amp rating. That is the only rating that is standard. A person can rely on this specification in that a given battery can sustain that specified discharge of current until depleted.

In a nutshell, pulse ratings are often not directly specified and if they are one must read the fine print as there is no standard pulse.

I personally ignore any pulse rating. As anumber1 stated, there is no industry-wide agreement on the terminology. It means absolutely nothing to me. Pay more attention to the continuous discharge rate. That's the important spec along with the mAh rating.

Depending on how long the 'pulse' is, a VTC can go from room temperature to a dangerous high temperature of 115 degree C in just under 80 seconds.

Which means if you set up your build above the continuous amp rating of the battery, forget to lock your mod and it fires when you put it down, the battery will vent when it gets too hot.
