The Watt's Up Watt Meter & Power Analyzer is the ultimate accessory for the die-hard LiPO enthusiast!

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

Connector to use a receiver battery for measurement down to 0 V

Captures current peaks and voltage minimums(droops)

Accurate & precise - 0.01 A current and 0.01 V voltage resolutions

Rugged - handles 50 A continuous and 100 A peak at 60 V 14 ga., 7 x 37 stranded, high temp silicone rubber insulated wire without connectors

Small & Light: 2.8" long x 1.7" wide x 0.83" thick (70 mm x 44 mm x 21 mm), 2.5 oz.

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

Energy 0-6500 Wh, resolution 0.1 Wh. That's lifting a 50 pound model into outer space (65 mi.)!

Operates from 4.0-60 V, 0 V with optional receiver battery pack

16 x 2 STN LCD display

Powerful, 8 MIPS micro-controller

Applications:

Specially designed for 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

Measures a full battery charge

Check when peak currents are safe for battery, motor, wiring and connectors

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.

Fine-tuning your electric airsoft gun for great performance doesn't have to be a guessing game

Measure power and energy consumption of ANY device with a rechargeable battery pack

Combine the power analyzer together with Tenergy 2.4V - 7.2V, 7.2V - 12V, 24V NiMH universal smart chargers , and with 3.6V - 14.8V Li-Ion/LiPO battery charger It is perfect tool to monitor battery pack's performance

Note: In order to measure the capacity of battery pack in charging condition, the battery pack must be discharged fully before measuring. 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 use the meter to judge battery nominal capacity, because usually nomimal capacity is measured by IEC standard at 0.1C charging and discharging current.
