Power Shield reverse voltage and short protection safety circuit from RC packs.
Features
Prevent your cables from fires due to runaway power supply of RC packs (which don’t have current limiting safety circuits) if cables are misconnected or accidentally shorted.
The Power Shield has reverse voltage protection and a 2A polyfuse (self resetting).
The PCB comes prewired with a Fat Shark compatible barrel connector and a bare pad to solder on the appropriate battery connector.
Purpose of Device
It’s tempting to power FPV equipment off RC packs as the voltage is correct and the average modeler usually has a few working packs that are a bit puffy and don’t want to use for flying anymore.
The problem with RC packs is they are designed for high discharge rates and thus have no safety circuitry to prevent runaway discharge should a short accidentally be introduced into the FPV gear.
The Power Shield adds safety by inserting reverse voltage protection and fused circuitry to prevent cable fires in the event of shorts.
