13S5P Panasonic/LG/Samsung cells, 14 lb, 2-year warranty, charger sold separately (FTH-CHG48DC5). Seller's compatibility list mixes external-battery models (RadCity 4, RadMini 4, RadWagon 4, RadRunner Plus, RadRunner 2, RadExpand 5, RadMission) with semi-integrated models (RadRover 6 Plus ST, RadCity 5 Plus, RadRunner 3 Plus, Radster Trail) - physically one pack cannot fit both, so the list is treated as unreliable.
