A separate topic so it doesn't get lost elsewhere.
Wet lead acid batteries are not allowed (i.e. the ones with battery acid in them).
Gel filled sealed lead acid batteries are allowed.
The battery should not be larger capacity than it needs to be to power your horn. Anything bigger than a typical motorcycle battery is going to attract the attention of the scrutineers. Don't try fitting a tractor battery as "stealth ballast".
Rule of thumb; if you're using it to power your horn, it counts as a battery. If you're using it to power your stereo, it counts as ballast. If it's big enough to power a submarine, it's ballast.
We're considering re-wording the rules to allow small Li Ion and Li Po batteries for small ancillary equipment (gps, camera etc). It's the large "laptop size" batteries we want to avoid.

Oh these goes my plan of using an 18 wheeler truck battrey to power a horn. Anyone have any ideas if these are allowed? It does not mention gel filled in the description. www.maplin.co.uk/sealed-lead-acid-batteries-19363For avoidence of doubt, maybe it would be a good idea to specify a max weight for battries, say max combined weight of 2kg for all battries onboard a cartie? Li-po and Li-Ion battries are allowed providing they are less than 100g and internal to the device which they power?

It's not immediately apparent from the maplin spec' and that item covers several batteries anyway. Best ask maplin directly if they are gel filled. We're not going to be taking batteries out and weighing them separately, but everyone inspecting the carties will know the difference between a motorcycle battery and a car battery and will have no difficulty at all in spotting when you are trying it on. Just gonnae no dae that.

Back in the day we DID actually use a heavy duty car battery to power the electrics. It was held in with Gaffa tape.......After the first event we discovered it had punctured the floor........so what did we do ?......fit a smaller battery....?......of course not ! we strengthend the floor !
This is why we need rules / guidence.......

Lee's Maplin sealed lead batteries are NOT gel Batts (not at that price) ...LOL. I know how much gel filled batts were for Robot War creations...!

I have previously used a 'sealed' lead / acid to power horns (Small - size of motorcycle battery - weighed circa 1.5Kg) - however, it was cheap and I asume it was liquid, not gel. I've decided to go with a Ni-cad nicked from an old 12v power drill. This should meet the new regs ? (Weighs 500gms which suits me fine)

Is LiFePo4 allowed?

Again Stephen is the person to decide but simply cutting and pasting gives the answer: Since the SCA Committee concern was in regard to exothermic reactions with Li-Po batteries I would have thought this type of battery solved the problem.

peasnbarley's answer above is not definative. I'll let you know when we've had word from our resident battery expert.

;D As I said Stephen is the person to decide so the definitive response to my post should perhaps have been S.T.F.U Charlie. ;D

;D As I said Stephen is the person to decide so the definitive response to my post should perhaps have been S.T.F.U Charlie. ;D I thought the UKGSA executive had previously voted on this (I wasn’t present) and the definitive response was to be be made totally automatic. Yet it still appears there’s a need to make this stock reply to all your posts. I’m very disappointed that this rule change has not been fully implemented. Why should we all waste time constantly having to reply "S.T.F.U Charlie ;D"

;D Team-Art: Your erudite posts are generally succinct and to the point but often alas lack Jurisprudence. The UKGSA is an English organisation and I don't believe anybody in that organisation would ever use, even in abbreviated form such an expression as you suggest as it is derived indirectly from the Gaelic.

"The UKGSA is an English organisation"
Yet more irrefutable evidence (were it needed) that this automatic definitive response system must be implemented immediately. ;D

Geographically UKGSA organisation is based in England and to my knowledge have no activities in Scotland. As to the actual UK Union it would be true to say the English stationed troops just south of the border and in Northern Ireland as an "encouragement" for the Scottish Lairds to sign. Months of fierce debate in both capital cities and throughout both kingdoms followed. In Scotland, the debate on occasion dissolved into civil disorder, most notably by the notorious 'Edinburgh Mob'. Strange how history repeats it's self. ;D
