Now this is an essential gadget to ensure peace of mind when skirmishing with modern lithium batteries. The compact and lightweight design will allow the operator to carry the device in the field or place the Voltage Tester inside a handgrip, stock or PEQ box. Unlike a MOSFET it doesn't require any installation and will fit virtually anywhere because it's so small. A stupidly simple yet effective way of warning you when the power of your Li-Po is getting low, thus protecting your battery.
The Voltage Tester is powered by the battery itself so there is no need for another power source. All that is required is to plug the balance port into the left hand side of the tester, which will then emit a very audible beep. The LED display will cycle through the voltage of each cell and the total voltage of the battery. The user can even select the voltage reading that will sound the alarm by pressing a small button on the top of the Voltage Tester, or even turn the alarm function off. The Voltage Tester is also compatible with a variety of battery types.
Why is the Voltage tester so useful? If a lithium battery is over-discharged it can effectively stop the battery from working again, an expensive mistake. A well cared for battery can be cycled up to 600 times, thatís a lot of skirmishes! But when youíre in the field you donít have time to be thinking about batteries, so this little gadget will do it for you.
