I purchased a used Typhoon H with 2 batteries. One is the Power 4 and the other is Powerextra TYP-H001. Both batteries give me the blue error LED when hooked up to the OEM charger. When I hook them up to my LiPo charger, the cells values don't register for balancing, so cannot charge. I tried cleaning the contacts with alcohol, but still nothing. Any ideas to fix this without taking apart? Thanks
