The MC2's slots accommodate batteries up to roughly 71.4mm in length, which covers the M50LT's length comfortably.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"98:1-99:249;5341-5655\"\u003e\u003cstrong\u003eQ: How long will it take to fully charge an M50LT on the MC2?\u003c\/strong\u003e A: Since the MC2 charges at up to 0.5A per slot and the M50LT has a 5000mAh-class capacity, expect a full charge to take several hours. This charger is better suited as a portable or backup option for these cells rather than a primary fast charger.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"101:1-102:136;5657-5845\"\u003e\u003cstrong\u003eQ: Can I charge both batteries at the same time?\u003c\/strong\u003e A: Yes.
