FEATURES | - Fine-tuning your electric RC cars & planes for great performance doesn't have to be a guessing game. Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V) for any rechargeable battery pack from 4 - 60V, including NiCd, NiMH , and SLA, and Li-Ion battery packs
- Small & Light: 2.8" long x 1.7" wide x 0.83" thick (70 mm x 44 mm x 21 mm), 2.5 oz. That's lifting a 50 pound model into outer space (65 mi.)!
- Acts like a wire so doesn't affect model's performance. Precision current sensing resistor, with only 0.001 Ohm resistance and circuitry only draws 0.007 Amps
- Uses DSP to increase ADC resolution and differential measurement amplifiers to increase noise immunity Factory calibration stores constants in EEPROM to compensate for component tolerances
- Accurate & precise - 0.01 A current and 0.01 V voltage resolutions. Connector to use a receiver battery for measurement down to 0 V

# 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. |

BATTERY SUPERSTORE WAS GREAT ABOUT A REFUND by Patrice L. Belcher  5 Stars
January 20, 2009
I could not use the item I bought from Battery Superstore and I sent it back. They were great, and credited my card. I am very appreciative. Did not get to use the item since my electric bike broke.
