Hi, I'm of the opin that device maximum operating ratings should be clearly spelled out in the manuals. For the TeleMetrium V2, the output MOSFET is a SI7232DN, which according to the data sheet has a max of 25A continuous and 25V. There was a recent request on the forum for this.
I recently did a bad thing. I hooked a LiPo 2s Batttery to my TeleMetrium, and smoke poured off the bottom. Then I revisit the manual, which talks about 1S LiPo but does not seem to mention a max supply voltage for the TeleMetruium. I poked at the schematic, and there is a TC2185−3.3 voltage management chip. Now that I look at the data sheet, it has a max input voltage of 6 volts. Hopefully, it's just the voltage management chip and not everything down stream. I assumed incorrectly that it could handle a higher input voltage. So please, please spell stuff like this out very clearly in the manuals. Thanks, Curtis
