    santi heated vest

    Can you use a light for me battery rated at 14.4 volt on a santi heated under suit rated at 12v, if so what if any are the risks.
    I take it it ohms law volt / current equals resistance and the vest would work at a higher wattage but is it still ok or is anyone runs a vest like this.
    Sorry if anyone feels this is a stupid question but i was assured this would be ok but i am not sure.

    Thanks and safe diving

    No, the vests are only rated to 12v, so you risk damage to the best and potentially burns by using a higher voltage.

    I think you would be OK. Santi products are made to be robust. It will dissipate more power and therefore heat (P=V2R).

    Best thing to do is try it out on land for a while before you take it underwater.

    santi heated vest (versus Icebreaker)

    I had a very similar concern.
    I have a Typhoon Icebreaker heated vest. Although the Exo2 heating panels are not meant to 'short circuit' and cause a hot spot, this has happened to my vest. The battery and connectors are fine and I am contemplating purchasing a Santi vest and simply hooking it up to the original Icebreaker battery.
    Has anyone done this and if so, did it work (from a voltage point of view, as the Icebreaker battery pushes out 16 volts once charged) and what was the burn time (as I note that the battery of the Icebreaker is 4amp/h and the Santi 20amp/h.)

    Re: santi heated vest

    I've been using a Santi Vest with a 10cell 15Ah NiMh Battery for the last 4 years.
    Charged, the battery puts out 14.5V for quite some time before it drops to the rated 12V for a total of 3 hours. This is still working well w/o burning my skin even though I wear the vest against naked skin under my Weezle Extreme +. I usually need over an hour of 4°C water before I can comfortably leave the heat on for more than a few minutes. After 2 hours, I just leave the heat on all the time.
    When I built the pack I added an audible low voltage alert set to go off as soon as the battery drops below 10V under load. I'd rather destroy a battery before getting dangerously cold, but want to know what I'm doing when I'm doing it.
