JustGav Posted May 12, 2009 Share Posted May 12, 2009 Look at a diesel car battery... I put a BMW diesel jobbie in my old bmw, bit of a tight squeeze but it certainly had the crank amps. Quote Link to comment Share on other sites More sharing options...
Gruggs Posted May 12, 2009 Share Posted May 12, 2009 the M5 battery is a bit of a beast. Couldnt believe the size of it when I changed it. Quote Link to comment Share on other sites More sharing options...
Axle Posted May 12, 2009 Share Posted May 12, 2009 You checked this site out? Optima have a battery for Marine applications (amongst other powerful batteries). Not sure if you could make that fit? Quote Link to comment Share on other sites More sharing options...
Multics Posted May 12, 2009 Share Posted May 12, 2009 What sort of power do you require Jamie? Cranking power for starting or deep cycle to run ice etc? Either case, have a look at the Optima Red Top or Yellow Top: http://www.optimabattery.co.uk/english_optima/red_top_optima.htm There's some good battery info on that site as well Quote Link to comment Share on other sites More sharing options...
Supe Posted May 12, 2009 Share Posted May 12, 2009 the M5 battery is a bit of a beast. Couldnt believe the size of it when I changed it. The 530D also has the same one IIRC. Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 12, 2009 Author Share Posted May 12, 2009 Cheers for the links guys. What sort of power do you require Jamie? Cranking power for starting or deep cycle to run ice etc? Either case, have a look at the Optima Red Top or Yellow Top: http://www.optimabattery.co.uk/english_optima/red_top_optima.htm There's some good battery info on that site as well It is for my Boat. Optima marine battery looks promising, i have a optima in the Supra. Why would it have to be a marine battery? the one in there now looks like a normal car battery. Needs to start the engine and run my audio, Ai audio is installing a stereo upgrade next week including a flip down TV in the cabin and i want the best battery i can get in there (maybe a couple of them) to ensure i have enough power.

Terminator Posted May 12, 2009 Share Posted May 12, 2009 I would think the M5 battery would take some beating. It will run electric heaters, heated front and rear all four heated seats and more for ages on winter mornings before you even start the car. Would that be enough or are you building and electric drag car? Quote Link to comment Share on other sites More sharing options...
Kranz Posted May 12, 2009 Share Posted May 12, 2009 This is a mother of a battery http://www.carbatteryshop.co.uk/i-610-200-Varta-Silver-Dynamic-Car-Battery-12V-110Ah-Short-Code-I1-Varta-DIN-610-402-092--I3200.html Quote Link to comment Share on other sites More sharing options...
bluecoup Posted May 12, 2009 Share Posted May 12, 2009 if you go to the varta site you can type in the size of the space you got etc Quote Link to comment Share on other sites More sharing options...
supra matt Posted May 12, 2009 Share Posted May 12, 2009 Surely ai audio will be able to sell and spec you a battery as most car audio installs require a decent battery and afue power caps if your going to be running subs and afue speakers .

JustGav Posted May 12, 2009 Share Posted May 12, 2009 Wouldn't it make more sense to have a small gennie rather than a battery? Quote Link to comment Share on other sites More sharing options...
Kranz Posted May 12, 2009 Share Posted May 12, 2009 Wouldn't it make more sense to have a small gennie rather than a battery? Probably both would be a good idea, depending on how long JP is planning on staying on the boat? The advantage of a small petrol gen set is that 240 volts would be supplied as well as charging the 12v battery(s). Quote Link to comment Share on other sites More sharing options...

Supra-Brett Posted May 12, 2009 Share Posted May 12, 2009 Nah, all them are good, but none are as good as this one http://caraudiosecurity.com/shop/product/products_id/5202/referer/rc_froogle.html I have one of these as an additional secondary battery, charged via a split charge system on my pickup at work. Its almost indestructable even with 4 x Gas discharge floodlights on the top of the truck, it just keeps on going. Quote Link to comment Share on other sites More sharing options...
madmarf Posted May 12, 2009 Share Posted May 12, 2009 defo go optima, ive got 1 tank that runs 48 volt. had 4 ginormous batterys in there and when i swapped them for pidly little optima red tops it crank so much better and so much easyer. i now use them on everything, all the tanks and monster trucks. gonne put one on the supra aswell. maybe £140 but trust me well worth the money, they only need 1 cell to continue running as the army tested with a rifle Quote Link to comment Share on other sites More sharing options...

1JZGTE Posted June 8, 2009 Share Posted June 8, 2009 I know a little bit about batts, so am qualified to advise. This will make some of you raise an eyebrow or two, but, having owned an Optima I would not buy one. Ever. Again. They are far far far overrated and overpriced for what they do. Put it this way, I don't know of many pro SPL and ICE competitors who use Optima, most use HawkerOdyssey or Redflash batts instead. An Optima is fine as a pure starter battery, whether it is their redtop, bluetop or deep cyle yellowtop. But, the minute you start to draw serious current, it will drown as the avg yellow top is only 55Ah and 690 CCA. There are plenty of deep cylce gel batts out there for half the price of an Optima. Look to get the biggest CCA and Ah rating you can. Some ideas for you: 75ah 760CCA (compare that to 55Ah and 690CCA from an Optima YT) http://www.tayna.co.uk/067TE-Exide-Car-Battery-X-Tra-Plus-XTra-Plus-XP07-P7499.html 105Ah 900CCA (compare that to 55Ah and 690CCA from an Optima YT) http://www.totalbatteries.co.uk/i-Numax-CXV27MF-Sealed-Leisure-Battery--12V-105Ah-900MCA--500-Cycles-I3791.html Under £90 shipped to your door for either of those.
