12 Volt 1 Amp Battery Charger

# Specifications: # Voltage 0-60 V, resolution 0.01 V. That's a 14 cell series li-poly pack! # Current 0-100 A peak, 50 A continuous, resolution 0.01 A # Charge 0-65 Ah, resolution 0.001 Ah. That's ~32 Amps for two hours! # Power 0-6500 W, resolution 0.1 W. That's ~8.7 Horsepower! # Energy 0-6500 Wh, resolution 0.1 Wh. # Operates from 4.0-60 V, 0 V with optional receiver battery pack # 16 x 2 STN LCD display # Powerful, 8 MIPS micro-controller # Color: Electric blue or green Applications: Specially designed for RC Battery Packs to help you: # Set speed control cutoff voltages and currents # Tune performance by comparing different setups of pro-peller, motor, gearing, speed control and battery # Measure a full battery charge and compare to spec when charger claims done # Check peak currents are safe for battery, speed control, motor, wiring and connectors # Predict airplane flight time based on ACTUAL conditions in your model # Check battery capacity and health and whether battery should be retired # Verify that the minimum voltage under load is within specifications # Check for wiring and connector power losses. # Measure power and energy consumption of ANY device with a rechargeable battery pack, such as # Airsoft gun battery pack # Bike lighting battery pack # E-bike and Scooter battery pack # Combine the power analyzer together with our 2.4V - 7.2V, 7.2V - 12V, 24V NiMH universal smart chargers , and with 3.6V - 14.8V Li-Ion battery charger It is perfect tool to monitor battery pack's performance Note: In order measure the capacity of battery pack in charging condition, the battery pack must be discharged fully before measureing. 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.

Shoffner 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. 11 of 11 people found the following review helpful. Listed as a toy but it is a good tool By Paul54 I purchased this meter after learning about it on a few of the solar power forums on the net. I am using it to monitor a small home solar power system. So far I am very pleased. I especially like the fact that it will measure amps and watts over time, along with minimum voltage and peak currents. I would say it is indispensable for maintaining or tuning a small solar set up. I have only been using it for a few days but if it lasts I am very pleased. The 60 amp limit is a real plus. 8 of 8 people found the following review helpful. Excellent Buy By pjltech This device is being used as an eBike power monitor. It's very easy to install and works exactly as advertised. Shows instantaneous Volts, Amps,and Watts. After a ride, it shows the total energy used in WattHours, and the peak current and power used during the ride, as well as the minimum battery voltage. Extremely useful for monitoring battery consumption and condition. It will not quantitatively display regenerated current but it does show the rise in battery voltage during regenerative braking. Excellent product; excellent price. See all 15 customer reviews...
