Finally got my battery/charger yesterday in the mail. I wound up taping the power leads from the Tiger to the connector to check that it would power up, etc., which it does. I've ordered a female connector to match the battery's output to solder to the Tiger's leads - thought I was ordering from a US location that turned out to be Hong Kong (just love Ebay), so another three week wait on that. But I should be able to check everything out tomorrow with it jerry rigged the way it is.
Gizzard, I seem to recall you saying you were going to take a stab at a truly English user manual, but maybe I'm misremembering that. Any progress?
