Spoken to them, do know thier bussiness. There is also Blackheath battries, but they have no web site.
Lincon bateries are shipped dry, which means you get the battery factory fresh. I've decided on Optima RTS2.1 there only six volt battery. 200mm x250mm x 90 mm, 45 amp hr but with a crank of 815 amps! Also teh benifits of shock proofing fast charge will stand sitting about better than conventional, temp ranges etc.
