[NSRCA-discussion] battery question

[mike mueller]

 What was the brand of chargers at the Nats whose balancer worked as a power adder and not one like the TP 210 that works by drawing the current out to balance thus getting hot? Mike

I have a set of matched packs, what i notice at first is they charge well and the balancer doesnt get to hot, later in their life the balancer works more. So my assumption is they go out of balance more as they age.

A related question: Is it true that the cells are "matched" in a pack? If so, what advantage would that have?
 
Thanks, Michael Ramsey

Yes :)


If a cell puffs it is easier to replace in a 5 cell pack.  Also cheaper to replace a 5 cell pack if a cell goes pre-maturely and you do not like to replace cells.  You might find use for a 5 cell pack by itself.  Smaller plane, Heli etc.  The downside is that you have to add a little weight for a Y connector to connect both packs. 
A 10S pack is a "little" easier to secure in the plane.  I will probably only buy 5 cell packs from now on.  Currently trying out the True-RC packs.

Other than cooling is there any down side to a 10s brick as apposed to two 5s packs?
