"Do not attempt to charge other 26650s in the R50, the included battery is specially made for the R50. The special 26650 will also most likely not work with other 26650 lights. Other 26650s can be used in the R50 if they fit but cannot be recharged." (節錄自 Olight R50商品頁面)
可見R50隨付之26650為特殊規格，僅能供R50使用/充電; 故不能適用於其他電筒(充電器也是??)
