How to relocate the battery to the boot

"ah i will have a look saturday grant! I found out the battery box is mainly for tracking apparently alot of cars where the battery is relocated have to have it in a battery box to protect the road car and driver / passenger from battery acid / acid fumes should they be involved in an accident. However i believe this is only going to be for those who are interested in making their car a full ball track car and entering competion racing (which of course is not really relevant for me) i beleive for just minor track days and one off runs i think you should be able to get away with it. Having said all this however a battery box is about 20 quid and if it can protect you from possible injury from the battery fumes should you be involved in a rear end shunt then surely its worth the money."
