but I couldn't get things hot enough to solder..
£45 should get you a nice hydraulic crimping tool from the bay of e. Search "hydraulic crimping". I got on to do the landy multibattery setup. It paid for itself in about 3 hours. I figure if it last a couple of years and does a hundred or so crimps its cheap enough. Chinese made in a red blow moulded case.
l've had it for years, crimped thousands of lugs with it, fit cable into lug and hit with hammer....simples....
