I've been looking at this Mitec 4 port multi charger, would it be overkill for our drone batteries? This single charging with 5 batteries is for the birds and at $50 a pop the stock chargers aren't very cost effective for what you get. If I could charge 4 batteries at home or on the road it could prove very useful. If I can accomplish this cheaper I'm all for it, I haven't been into RC since before the lithium days so I'm a little behind the curve.
