Remember, good consistent and accurate ground testing of your airborne packs requires a "loaded voltmeter". Open (or unloaded resting) voltages can fool you into thinking a battery is OK to fly again when it is not. Thus the reason RC hobby meters have load capability.

RC Voltmeters and Pack Testers
Knowing the real voltage of a pack before and after a flight is one of the simplest ways to protect batteries and avoid a dead-stick landing. This category collects voltmeters and pack testers for checking flight and receiver batteries.
Onboard and Handheld Meters
The RRC Digital Onboard Voltmeter reads from 3.5 to 30VDC and can ride along in the model, while a digital multi-meter covers general bench testing. The Cell-Meter 7 and Hitec LiPo checker read individual cell voltages on a lithium pack.
Pack Testers
The Insta Check Pro RX/TX pack tester gives a quick check of receiver and transmitter battery condition, useful as a pre-flight habit at the field.
Regular voltage checks catch a weak cell or an over-discharged pack early, which extends battery life and reduces the chance of a failure in the air. Keeping one meter at the bench and a small checker in the field kit covers most needs.
