E2E Forum,
I am considering employing a relatively high power (cell continuous discharge max 10A) 3s2p Li-ion pack: Molicel, INR18650M35A-V2-80096 pack for a relative short duration (9 months max).
In general I understand the pros of balancing cells in a series but I'd like to know if this particular balancer (or better recommended balancer) is "right" for a 3s2p pack.
For example, over a short 9 month duration balancing a pack may save approximately y amount of energy (may be more appropriate to say one maintains y amount of capacity) though the balancer consumes x amount of energy. At this point y is difficult to determine because I do not have each cell's exact capacity, resistance nor or other lesser battery parameters. However, I should be able to determine x though the average current/voltage/power consumed by the balancer though these values obvious (at least to me).
Questions:
1. In general, does the industry recommend/demand a balancer for a 3s2p Li-ion pack for a 9 month duration? I have done a little digging though I have not found a good paper tackling this topic,
2. How does one determine how much power this balancer consumes at least on average?
3. Is this an appropriate balancer for this pack or does the forum recommend something else/better?
4. Pins "BAT1" and "BAT2" are a little confusing to me (primarily why are they separated). I ask because it is tempting to not connect the pack parallel cells (modules) and individually connect each cell to each port (6 total) of the balance and maximize the balancing of each cell versus each module (2 cells in parallel). To clarify, it is pretty clear to me that the part's data sheet recommends only stacking cells and corresponding balancer ports in series. Just checking to see how far one can take this part.
Thank you,
Craig
