I live in a rural area on Cortes Island short steep hills, I am making myself an electric bike with a long side car, all one piece.
Motors on front and rear wheels of the bike. I will be able to carry a passenger or a load of seaweed for the garden or firewood

the cells are Samsung 25R the battery is 10s 30p for 75Ah powering two 20A controller for 2 500w geared motors

I am building a 36V 10S 75Ah battery, I have not succeeded in sourcing a 36V 10s 75 A BMS, can I safely use a 36V 10S 80A BMS with an 80A over current protection
