Another couple of parts have just been ordered.

1 - watts up meter power system tester analyser

2 - 5pk of Gripy Deans Connectors.

The LCD display on the gun side will give feedback on voltage stability the battery is outputting, how many mAh are left (Roughtly 1mAh = 1 Fired bb) this means can esitmate shots remaining from the weapon.

Here is the spec of this module.

*********************
* Ensure peak currents are safe for motor, wiring and connectors
* Check battery health and whether battery should be retired
* Evaluate R/C battery charging efficiency
* Verify that the minimum voltage while operating is within specifications
* Choose the best propeller or gearing and the most efficient motor
* Check for wiring and connector power losses
* Measure power and energy consumption of ANY device with a battery

Key Features:

Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V)
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
One Year Warranty
Complete User Manual
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. 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

***************************

Here are some images of the module, the green case will be inside the gun and i'm hoping to use a Blue Gel/ Celophane pannel to make it a more bluish colour.
