Need someone to check my maths. Plus we need a call on this if we are gonna do this soon.

First

Battery: http://cgi.ebay.co.uk/12v-LEISURE...PageNameZWDVWQQrdZ1QQcmdZViewItem

Lights
http://www.anchorsupplies.com/leds.htm
Its the 3 watt hyper LEDs, Im thinking 10 of them.

Now by my calculations that battery will run all the lights for 34 hours. Someone check this for me.

We will need switches and wires as well, plus a Geoff to do the soldering wiring for us.

DO we want that battery. We need a call on it soon, how high will we go? The lights will be £35 if they are in stock. If not the battery will do whatever else we want to do. Its second hand but it dosent look to bad.

While I know nothing about whether you guys need the battery, the calculataions were of interest to me.

Battery life=Capacity(Amphous)/current (Amps)

The capacity of the L85 appears to be 85Amh (though they should of made that clearer IMO)

I=P/V

The power of each LED is 3W (each one recommends (3.5-3.8V, but I will assume that it gets that as required by wiring them as recommended). (10*3)/12=2.5A of current

Battery life=85/2.5=34, so I see no flaw in that calculation. I'm not an expert at electronics, but the fact I have the same answer is reassuring!

mker of custom batteries and a damn site cheaper than getting from shops.

The lighting is almost sorted, we have bulbs(probably be ok), we need wire (dirt cheap) and a battery

We are looking for a 12V leisure battery, at least 85Ah better will be 110. We are looking at £70 for one of these online, anyone got a better idea. We are pricing second hand car batteries but they wont last long in the cold with a slow drain on them. Same problem with batteries from component shop.

We need ideas for this now as we have 2 weeks until the next event.

I'd have to check but UI think my leasure battery is 110 and cost us around £40, have a look at the camping and caravaning shops around Cheshire, there are a few around Winsford.

Yea prices went up recently apparently cause of metal prices. I did see some last year for £40, now the cheapest even online seems to be £60 odd for a 110ah. Still looking but we spent an hour on it last night.

can we ceate some kind of peddle system and make josh peddal a bike so we can get electricity? alot more eco freindly!

Jimmy

woah woah woah monkey boy! if anyone is pedalling it's going to be you!

Why insult me, it was Daz who picked on you. Im really offended Wink

No one with any suggestions?

Just found out Geoff is tied up this weekend, chances are I wont have time to build the chandelier before the event. However we will all need to put up some cash for the batterywhen we go for it.

lol

John

Are you old enough to drink?

Ian I have been speaking to John over at JB components and they have (for a limited time) 85amp batteries in for £60 they are going up very soon.

Haskeer

arent you john?

Have you been talking to yourself again?
Its not a good sighn when that happens you know!

John

Its a bad sign when you argue with yourself and lose, but you'd know all about that wouldn't you? Wink

Ian he's putting the prices up this week, if they havn't already gone up that is.

dead

Im skint until after the event and there dosent seem to be that much interest from the rest of the group anyway. Itll have to wait till after the next event now.

Cheers for the help anyway

Lights £5 per person

£18 for the battery

We may need a few bits of wire etc. I need the money for them if we are doing it on monday. 95% sure it will work
