Due to the lack of 12s chargers available, a need for charging pairs of large 6s packs has arisen. A common battery pack for a 700 is a 12s 5000mAh made up of (2) 6s 5000mAh packs wired in series. Larger electric helis are becoming very popular and they come with large needs in terms of power. For example with a 350W charger a 6x parallel lead set, a new pilot could charge 6 450 packs in 30min. Parallel charging can be a great aid to the new pilot. This is what we call the "Welcome to your new addiction" stage. Many times people start with a 450 sized heli and in the beginning they can not get enough flight time. What are some specific uses of parallel charging? Read through the "Potential Drawbacks" section for more information. The charger then balances all the packs as if it was charging a single pack.Īnyone can do parallel charging on any charger with any batteries, so it is always an option but there are always trade-offs. Then not only do the packs all become the same voltage but each set of cells does also. Using this also ties all the like cells of all the packs together (first cell in all the packs are tied together, second cell in all the packs are tied together and so on). The charger only "sees" one larger pack and charges it as if it were a single pack.īut if the charger only sees one pack, how does it balance all the packs?Īll the individual packs will be balanced by the charger if a parallel balance adapter used. Current actually flows between the packs and they actually all adjust voltage until they all perfectly match each other. I am not speaking in metaphors here, they really all do become the same When you place all the packs in parallel, they all become the same voltage. This is assuming a few things of course but that is the basic idea and it is a good one to say the least. To charge a 3s 6600mAh pack and poof you will have 3 packs done in an Take all 3 packs, wire them in parallel, set the charger Say you have (3) 3s 2200 packs that you run in your 450 sized heli. To be connected in parallel to create a single larger logical battery that can then be charged. A nutshell parallel charging allows for multiple same cell count batteries
