[NSRCA-discussion] Advice on battery checkers

[Jay Marshall]

Whether you use a digital or analog, you should always check under a load.

A (good) digital meter will give accurate and repeatable readings while a
ESV will make it easier to "see" quick drops due to bad servos or heavy
loads when you move the controls (the digital meter will integrate the
samples). For these reasons I like the 'Voltwatch' but you have to have one
set to the correct voltage range. Techniques to do this are on the 'net.

Since it appears my new plane crash was due to a "new" battery failure or
some kind of high drain, it is time to get back into the habit of checking
the stinkin' batteries before every flight. This is a habit I had early on,
but 8 years in pattern and no battery problems made me lazy. I used to have
that cheapo $19.95 hobbico Expanded Volatge reader or some such, but what is
out there that I really should be using for my new $2000+ airplane?   Please
let me know what you guys think!
