    The Santi 6ah battery is rated to approx 90 mins.

    Unless you are doing very long hangs or cannot charge batteries between uses, then 90mins may be enough. Big batteries can cost over 1k on their own

    Run time

    Comfort

    Heating benefit

    Santi has exterior battery, I use an Ammonite Accu Thermo which allows me to vary the temp.

    Santi system is modular and allows you to add to the system like the heated gloves.

    Faff element

    I think that is about it

    Depends what you’re likely to do with it...

    For a Santi vest, even a 12Ah battery should provide over two hours at full heat (and, if using an Ammonite Accu battery, longer at the half-power setting).

    But, yes, heating systems are great, if expensive.

    You need a feck-off great big battery, 20ah or more.

    Toasty or shivering, your choice.
    What battery are you using for these big decompression stops?

    You're not doing underwater callisthenics on stops?

    I went for the Lola system with heated gloves, think it costs about £800 nowadays. It's marvellous and you get to pull a smug face while your toasty warm and watching your buddies freeze. On serious note I think they make deco diving much safer especially when you get to big numbers. Plus it gives you another tool to use if shit hits the fan and you need to get out quicker.

    My wife and I both have Thermolution heated vests - they are great and not just for big deco dives, I mostly use mine so I can do a nice hour dive at the colder times of year and not come out gibbering. The alternative for me is using a monster thick undersuit and an extra 5kg of lead which my back does not forgive me for. it Needs a bit of care, know other people who have broken the flexible wires and had to send it for repair, so be careful taking it on/off - batteries seem bulky on your side when you 1st put it on but honestly you don't notice them after 2minutes..

    What said diving was cheap? Buy well and enjoy the good choice you made.

    A larger battery (20ah or more) will deliver a weekend of heat and light and avoid taking dive kit off the boat (apart from crack bottle).
    I use the Light Monkey 20ah dual output for just this and my 35W HID cuts through the plankton the whole time whilst my heated vest keep me toasty.

    I've the 'standard' Santi heated vest, Santi "Thrmovalve" and a Light-for-Me 18AH heating battery

    The hassle is additional kit, making sure it's connected, loosing the blind connection plug, jumping in once without connecting the E/O cable and flooding the battery and killing the circuit board...

    However, I wouldn't be without it for UK diving except for summer.

    The big battery lasts for a 2 hour dive and a second shorter dive. Haven't flattened it, but have seen the charger say it's empty.

    As far as I'm aware, the small Santi 5Ah battery would last less than an hour, so far too short for me.

    (Maffs... 5Ah x 12v = 60Wh. Vest is rated at 50W, therefore an hourish and seriously flattening the battery which is generally considered poor form)

    Do like the Santi 24Ah battery. Seriously considering that as a replacement for the LfM battery if I can't get it fixed.
