I needed a couple of high-current-carrying lugs and cables for a set of batteries within a UPS (the previous owner had replaced four batteries with two and discarded the excess cabling), and fellow tinkerers on the GNHLUG mailing list suggest I check out the Electronic Surplus Services Store. I hadn’t visited their facilities since it was down in the mill buildings on the river — they’ve moved up to Candia Road now — and they had the parts I needed, as well as lots of cool toys to think about tinkering with.
