i though of separating my battery in 2 sections 2p 14 s for city . this means that if it got stolen i wont hurt me as much as if the whole battery is stolen. is 2p14 s relatively safe with a bms to use or i'm completely dreaming? i would charge it at 1 amp . what is the minimum of cells in parallel . Could one use a 1p 13 s to ride (total of 2.1amp x 48v= 100amph) divided by 20 it would mean 5 miles possibility..
1P is no good because the discharge amperage is only 8-10A (I am guessing as to what the specs say, but do confirm bc I cant remember) so when you do that, and you get 20-30A you hurt your babies.
2P means you can do 16-20A
3P means you can do 24-30A
4P is 32-40A.
Now you go with a 30A 18650 then its 1P = 30A, 2P 60A, 3P 90A, 4P 120A discharge.
You could have a small 1P or 2P and 13S pack which would net you 48V(nominal) and 30A or 60A but with them Makita's its only 10A and 20A.
