Proceed without a BMS at your own peril.
Best case, you ruin some expensive cells.
Worst case, you burn your house down.
I agree completely. Running lithiums without a BMS is like running your
house wiring without circuit breakers or fuses. When things work,
everything is fine. Look at all the money you saved!
But if/when something goes wrong, your house burns down.
Consider: You are going to use your lithiums until they die. And *when*
they die, one of their failure modes is *fire*.
It's nice if a BMS can prolong battery life, or give you lots of fancy
displays and blinkin-lights. But its most fundamental job is to prevent
a fire.
