I would definitely be interested in a PCB for this. I received some of those batteries, but the only way I've been able to use them is by breaking up some of the packs so I could charge them individually in my charger. ----- Original Message ----- From: "Olin Lathrop" To: Sent: Monday, April 15, 2002 6:57 PM Subject: [PIC]: PIC controlled NiMH battery charger > A bunch of us on this list received NiMH batteries for the price of shipping > last summer.
