rkcstr said:For those LiPo 10440 batteries, what do you do about the minimum voltage? I use some unprotected CR2s, but I have to check the voltage every so often to make sure they're not close to their minimum voltage. I do usually notice the output dropping, but only in the burning ability and not so much brightness.
Anyone have a good method for "protecting" the batteries? I thought about simply using a zener diode in series with the battery positive above the cutoff voltage, thinking once it dropped below it's breakdown voltage it would turn off, or at least greatly decrease the output so I'd know when to recharge. It would have to be rated at least 1.5W (I think) to be safe for mine at 400mA, though.
