MRC 989 Question

[luvsrc]

so you guys mean to say that i can use to charge my (2) 3s maxamps 5000mah lipos "just wire them in series "using a series adaptor and i can use the 989 charger or whatever charger capable of 6s and 5000mah?thanks for all the replies

You can do that as long as the 2 3s packs are balanced to each other. Meaning all 6 cells are the same voltage to start. If not you will overchagre the pack with the higher starting voltage. Most balancers have the ability to drain off small variations from cell to cell in the time it take to charge a pack, but if they are charged (or discharged) to different levels beofre starting you will likly ruin you packs that way.

The only time you should charge packs on the same circuit, wired in series is if you balance them together and treat them as a single pack, charging and discharging them together (like a dual emaxx pack setup)

Like Jhautz said, "You can do that as long as the 2 3s packs are balanced to each other"

The MRC 989 will also allow you to use a parallel connection for those 2 - 3S Packs, then charge at 10 amps. Same charging time to full.

I usually charge at a rate somewhat less than 1C though. This is said to lengthen the cycle life of the packs, over charging at the maximum rate.
