Average Reviews:
(More customer reviews)This item is marketed primarily by and in support of RC enthusiasts (toy makers and users). It, however, is not a toy and could cause harm if misused. I purchased the Watt's Up meter to monitor large batteries powering telescopes, associated computers, heaters and lights. This is in an outdoor environment subject to cold and moisture. Follow the instructions and be prepared to be delighted. Perhaps one of the few items on the market which delivers exactly what it is designed to do. Because my application is at night, I wish it had a backlight, but that's not a major problem. My astronomy gear is expensive, portable and uses DC power. The Watt's Up allows me to see what my electronics are really doing in the field, compared to what the manufactors say they are suppose to do. That means early warning for batteries, heaters, internal components (computers, motors and chip sets) and in the environment they are used. The Watt's up is well made, weather resistant, and compact. During a session, it even records relavant data and continually updates itself. It won't pour your coffee, but it will watch your DC systems better than you could without it. A very, very good buy.

For the battery pack stored for longer time, you need 3 - 5 cycle's charging and discharging to get full capacity.We don't suggest you to use the meter to judge battery nominal capacity, becuase usually nomimal capacity is measured by IEC standard at 0.1C charging and discharging current.
