shocks me why people try and go cheap on the things that make them money,
right just to get this clear I am not knocking any of these things posted, just making a point on ££ ok here I go bee in bonnet.
£10 a go may last ( I dont know)
£25 a go will last (if you look at it's wires build for job and more)
I dont have either and have three batteries which I charge every other day (mad I know and I am looking at this more and more, but would still carry extra battery just in case as it would cost to much to die for a day for the sake of a few ££
getting back to my point and small items that are low cost.
DO NOT scrimp on things that you need to make your system work, don't listen and you will pay the price this is fact sooner or later it will happen you will be off for a day or 2 till part arives you may have scrimped on £10 but that may have just cost £200 plus (answer buy the good quality not cheapo to save a pound or three )if going for a spilt relay always have a back up battery with you, again dont listen and it will cost you one day.
This guys is fact not fiction.
