I can't find a reference and answer to this exact question... Can you charge Lithium Ion batteries that have a built in USB port by sticking them in a standard bay-type charger? Any concerns or exceptions?
I have 4 Streamlight-branded onboard USB 18650's that I keep exclusively for my Protac HL 5X. I always charge them with USB cables but I'd like to stick em all in a charger.
