Firing System Battery Voltage

    So as the weather was so nice yesterday, thought I'd take out my recently acquired SuperbFire 32 Cue system and have a quick play.....

    Connected up the enclosed battery:

    , which instantly showed a charge of:

    I don't yet have a charger to charge this up (will be buying one soon) but just wondered - what should this show for a fully charged battery? Is the above '12.5' showing a high or low level of charge?

    I also connected up 2 igniters to test - one was a consumer match igniter and the other was an electric match igniter, which both fired from the remote when I was about 20 metres away (other end of the garden - I can also just about get up to 25 metres away if need be).

    Regarding the consumer match igniter, I wasn't totally convinced that this would light a cake viscos when connected to the igniter as obviously, the viscos goes through one hole of the consumer match igniter and out the other - doesn't appear that there would be enough surface of the visocs actually visible in the igniter for the resultant flame to catch but I guess, the only way to be sure would be to test several of these....

    Thoughts...

    Was that the AA's or SLA battery? (I can only view the 3rd pic)

    ......that was the SLA battery!!

    Quite impressed with the system really - the remote reaches the system from one end of my garden to the other without the extension pole you gave me, but always good to have, too!

  6. is there an equivalent chart for 6v sla's ?

    @Wireless Pyro Solutions Can I also ask - will cues fire ok (with a fully charged battery) if you are firing cakes, say 10 to 15 seconds apart (i.e. I press cue 1 and then 10 seconds later press cue 2 and then another 10 seconds I press cue 3 and so on but with say 20 second intervals on all 32 cues) ?

    I used all 32 each year without issue, some had long wires, the shortest were 5m, longest 2 x 2 :)

  9. @deans6571 Yes, firing systems generally have enough battery capacity to fire multiple shows from one charge. The actual power used during firing is small as the current is drawn only for a fraction of second for e-matches. That 14Ah battery you have there will fire thousands of e-matches from single charge (neglecting the stand-by draw from firing system).

    ...nice one, much appreciated.

  11. Used a pyromate system that has internal x2 12v 2 ah converts to 24v fired over 328 cues in 17min with some good cable length of 800ft
    impressed :nicesystem:

    If you consider that a standard igniter will fire with 500mA for 25ms then work out how many (few) amp hours that is, self discharge and the indicator lights use a lot more power than firing the cues.

    ..another quick question on this - perhaps better answered by @Wireless Fireworks

    My SLA battery is currently showing a charge of 12.3 (haven't charged it yet since buying from @K9Girl in January this year - seems to have held its charge pretty good!) and going by the above chart, is around 70% charged.

    Whats the 'done' thing here with these batteries - charged them to 100% before every use or use them until charge drops to the uppermost red areas?

    Lead acid batteries work better and last longer if kept close to fully charged, I'd consider recharging before 50%SOC is indicated. I'd also consider a recharge in the summer simply to prevent the battery sitting empty for months and being too hard to recharge in November.

    The LEDs on a firing system take more from the battery than all the cues, and they take their energy first -then you have to have enough left to fire the cues.

    I've no idea what the correct thing is @deans6571 but your battery was always fully charged up before a display, then left until the next one ;)
