You’ll see the term
replace the zeros with other numbers, example 10s3p 6s4p
This is a shorthand version of 10 batteries in series with 3 of these in parallel
Batteries in series increase voltage, which in turn increases power.
Batteries in parallel increase amp/hours, which in turn increases your battery time/range of your board
How does series work?
It takes multiple smaller voltage based batteries to create one larger voltage battery. A common example of this is a Car battery which is actually 6 small lead acid batteries in series. Each of these cells are just over 2 Volts each connected in series creating one 12 volt battery.
This will read in terms of the above short hand as 6s1p
Another thing to note though that a 6s using LiIon or LiPo will actually be a higher voltage as each cell is approx 4volts each.
So a 6s battery will be about 24volts
Parallel, the best analogy I can use here in relation to cars is that each P is a tank of fuel
So a 1p battery has 1 tank of fuel, a 2p battery has 2 tanks of fuel so on
So obviously a 4p battery will go almost (because of weight increase) four times as far as 1p battery
Hope this answers it all in layman’s terms for you
