Recently, I started making a list of parts for my first eFoil build, and I’ve just gotten to the battery, and there’s a lot more information to unpack than I expected.
First of all, I know you can buy a lipo, or build a battery with individual cells (the Samsung q30 looks to be popular and reliable)
If I were to build a battery, how should I decide whether I want 12s12p or 14s14p (the two main configurations I’ve seen so far)?
Would I want to split the battery into two sets of 6s12p or 7s14p? What are the benefits of doing so?
At what point should I use BMS, and is BMS unnecessary if I use a low voltage alarm for during use?
How do I test the individual cells before building the battery, to ensure I don’t use a faulty cell?
How do I know which BMS I should purchase, if it is necessary?
What kind of charger should I get for the battery (or batteries if I go for the 2 set option)?
If it makes a difference, these are some of my main components so far…
I’ve read @Flightjunkie thread on batteries, which was really helpful, but in some ways, it left me with even more questions than when I started (probably a good thing).
Lastly, I know this was a really long post, and I don’t want to take up too much of anybody’s time, so please don’t try and answer all of my questions, just point me in the right direction and I’ll do the rest.
Thank you to everyone that bothered to read all of this, it turned out to be slightly longer than I expected, but hopefully other people will be able to benefit from this thread as well as myself.
