How do you check flight batteries?

Quick question....
I have a volt meter and can someone explain how to check the battery voltage both under load and with out load?
What values should you look for?
Thanks much,
Ryan

I charge my batteries when my loaded meter reads 4.6.. and if I
remember correctly 5.4v with an unloaded meter.. At least that's how

Hello
I was worried that one day I would get over excited and fly until my Batteries ran dead...
And so not wanting to practise my death rolls I installed a Quick UK On Board Battery Monitor...

You can tell the voltage by looking at which LED lights up...
The unit plugs into a spare receiver port... So at a glance you always know where you are...
If you turn your Volt Meter three clicks to the left... It should read Volts - 20, and then put the probs into a spare slot on you receiver, this should also give you the current read out...
But the battery monitor works a treat and looks great...
Hope this helps...
Cheers

You need a load on the batteries to get a true reading of the voltage available. Without the load you will get a false reading that is actually more than you actually have. A cheap expanded scale voltmeter is available at hobbie shops. Best insurance there is. The scale will tell you when it is time to recharge.

There is a construction article on my web page about a simple, inexpensive loaded test unit done by battery guru Clifford "Red" Scholefield. It has instructions on how to build the unit and how to use it.
