    IR Meter Recommendations

    Does anyone have a recommendation for a good meter to check IR (Internal Resistance) of various battery types? I haven't checked this in the past as the testers I use (Opus) aren't very accurate. There have been a lot of requests to test this in some of my videos, so I'd like to start doing so...

    AIMS LF Inverter RJ45 Protocol Information

    I'm attaching the documentation for the RJ45 pinout and protocol information. AIMS technical support happily provided me this information when asked.

    Today's starting battery teardown is an X2Power CYL10030. I can't find much at all about this one online. It looks like it may have been sold by Batteries+Bulbs, so maybe something exclusive to them that's now discontinued? I'm not sure. It's a 36Wh LiFePO4 battery that states it's the...

It's typically not something one can simply download and run. BUT, considering we have (in my opinion) a great...
