I've searched the forum, and (unless I missed something) I could find any thread(s) on this specific subject. So...I'm creating this thread to not only 'learn', but to (hopefully) prompt answers that will help other Speedrun nOObs.
In general, I'm quite familiar with running LiPos in parallel, as well as in series. As most know, when using two identical packs, running them in parallel doubles the output capacity (two 5000mAh 4S packs = 10,000mAh 4S), while running them series doubles the voltage (two 5000mAh 4S packs = 5000mAh 8S). For a couple of my crawlers, I'll probably run two packs parallel...and, with my boats, I run both ways (on different boats, obviously, dependant on the purpose/type of boat). Using two of my boats as examples, my P-Sport Hydro runs two mid-capacity 2S packs in series (as opposed to a single 4S, or two 4S parallel) to help keep weight as low as possible. However, in my P-Limited Cat, I run two high-capacity 4S parallel (one in each hull) to keep the cat 'balanced'.
However, where speedrun vehicles are concerned, I see, and read about, people using both...and, admittedly, I'm a little confused. For the purpose of the following examples, let's assume a person will be running 8S. On one hand, two 10,000 4S packs could be run in series. On the other hand, two 5000mAh 8S packs could be used parallel. Both examples result in the same capacity AND same voltage.
My questions are:
1) For the specific purpose of a speedrun vehicle, what are the advantages/disadvantages of each configuration?
2) For the specific purpose of a speedrun vehicle, is one configuration truly better than the other...and why?
