    Hi Colin
    Sounds like you have found the Ultramax 7Ahr LifepO4 being sold discounted at present so I would not wait too long if you want at this reduced price.
    I have used this type of battery in a smaller version to power my yachts for a few year and can confirm they do deliver the power.
    Cheers
    Dave

    Thanks Jonathan, I have found a direct lifepo replacement for my sla 12v 7ah battery. At only 35% of sla weight.
    It has a dedicated charger with it and free postage all for ยฃ55.
    So won't have to save too long. Cheers Colin.

    Colin,
    These are what I used. Also, this company posts a ton of information about it's products which you will find when you link to each product. Also, they offer chargers specific for these batteries. Explore the site. Also check out their information on SLA's, especially discharge and charging rates.
    Cheers
    Jonathan

    Thanks guys for the great information, as most of my fleet are using vintage electronics and it is important to keep this format for my vintage shows.
    The few I use for personal pleasure could be converted so I will need to start saving my pocket money or add items to my Xmas list.
    The LIFE battery solution sounds really good apart from the cost.
    NimH cells could possibly be my option to try as I have a few cell packs from my cars and quad copter.
    I'll let you know how I get on.
    Cheers Colin.

    Colin,
    I have a solutioon for your problem, but you will not like it. There are made LIFE batteries that are designed as direct replacements for the standard 7amp 12v SLA batteries that, on this sdide of the pond, are used commonly in alrm systems. They are in the same style case, with the same dimensions, but they weigh a fraction of the SLA, around 50+- % less. They have the advantage that they can provide high discharge currents, much higher than a standard SLA or even a high discharge SLA.
    Te BAD news is the cost, on two counts. 1) the batteries are expensive, $180 amnd 2) they require a dedicated charger, around $30.
    They do have an additional benefit, in that they do not self discharge as SLA's do, therefore their management is quite a bit easier. I use these in my 1/16th PT boat and they make keeping the weight in tow very nicely.
    Sorry if this is a tease, but I am throwing the information out there.
