This 20 amp Naos Raptor breakout board was designed with those lithium-ion polymer battery users in mind. It measures 45mm by 11mm and has 4 addition outputs for connecting 2 or 3 wire ohm meters and voltmeters. The outputs connect directly to the positive 510 (VOUT), at pin 6 (VIN), positive battery connection (VCC) and a secondary ground (GND). Through these outputs, you add things like selector switches and build out your mod the way you like. This board is designed based on suggestions made by the box modding community worldwide.
Select your choice the enclosure, 200 ohm potentiometer, voltmeter and fire button. You can also purchase this PCB with all SMD parts populated (i.e. the small components). Delivery of populated boards may take 1-2 days longer.
