Currently, I have two single LiPO battery chargers but only one can put LiPOs into storage mode. With the growing number of cars (and batteries) I am looking to get a charger that will support charging of 4 batteries at once. I am kinda leaning towards two chargers that support two batteries each just in case one fails but that's not a definite requirement. The last charger I bought was probably around 8 years ago so I am totally not familiar with what's current these days. I am looking for a decent but budget charger(s). All batteries I have are LiPOs (2S, 3S and 4S) but ability to charge NiMH would be nice as some of the stock cars come with NiMH batteries. Any recommendations?
