G&P All-In-One Power Bank 7.4v 1600mAh (20C) / External Battery w/ Flashlight - Sand

The G&P AEG Power Bank is the perfect battery replacement to a PEQ battery storage as it will charge any front wired AEG, so long as it uses large deans connectors, and will still have a functioning flash light available. You can mount it to any rail system and it comes with a pressure switch as well. You can charge it using a regular lipo charger.
