Simple question. Confirm?
1) There is a BMS module on each battery block.
2) Even if not connected to the BMS comm cable the minimum BMS chip across
each cell does provide a very small amount of overvotage cell balancing if
a cell starts to move above a crticical voltage.
3) It can NOT actively byp

Proceed without a BMS at your own peril.
Best case, you ruin some expensive cells.

I agree completely. Running lithiums without a BMS is like running your
house wiring without circuit bre
Words to live by Alan. Hence the ask what BMS folks are using with Volt
packs. So far the majority I have heard is no BMS. And I have seen lots
of folks use a less than great BMS, it malfunction, drain and kill the
pack. The Orion and Dilithium kits look like good quality but would likely

Awesome, fantastic info Jerry! yes glad again you are ok too and too bad
about EV- hard to put a price on a one of a kind EV, like a lost art piece
:-(
Yes I am looking at running an AC setup - the Hyper9 X144 setup looks
impressive. I am currently running a Motoenergy ME1003 on a 96V DC setup

Hi Dan and All,Volt modules are very forgiving, robust assuming you stay
within voltage, temp specs. A major advantage is not having the cost, hassle
of a BMS which can increase cost 50-100%.In the trike I just paralleled the
