My batteries showed up in the mail today and with a little work, my LX NiCd pack is back in business. I'd ordered 350mAh cells but changed my mind when I saw how much trimming would be required and stepped it down to 300 mAh. Total price for parts and shipping came out to $40 US bringing the cost of my new motor drive to $145.00. Swapping batteries was a straightforward 30 minute job with the soldering iron. The instuctions at http://members.ozemail.com.au/~distudio/pentax_nicd_pack/ were spot on. As a bonus, the capacity should be double the original and NiMh cells shouldn't suffer from the memory problems. The downside of course is that my charge pack (thanks cotty) is now a 12 hour slow charger.
