Any idea what sized 11.1v Batteries will fit into the stock of a VFC SRX 309? I was thinking maybe a few of these https://www.airsoftatlanta.com/coll...ts/11-1v-1100mah-red-tiger-stick-battery-lipo Also how many will I need for a Milsim op in they're Lipo 11.1v 1100 mAh? I heard 11.1 lipo's have close to double the amount of charge as an NiMH battery with the same mAh, Is that correct? Also It's a 2 day op. ***Also I forgot to add. Should KWA KM4 Mid caps work with the VFC SRX 309? Thank you any response will be appreciated.
