The 11.1v 1500mAh Red Tiger Battery (LiPo). A solid 11.1 lipo for use in Airsoft. Measures 19mm x 30mm x 96mm in size. This is an awesome small sized 11.1v LiPo battery! It's around the same size as a 8.4v mini. We fit this in several AEGs that use mini size and it worked perfectly (P90, AUG, M4 handguard, etc..). Check sizes with the dimensions listed.See Technical Specs Tab for warnings and charging information. Requires LiPo specific charger.
