Sharkey, I sure *hope* you outlive your batteries!

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

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
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
cost

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

Bummer, what lousy luck. Sorry to hear that the trike was wrecked, but glad
that you're OK. I hope that you can
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
48vdc sections in the 4kwh module and fused each section/string in
Hi All,Tuesday I was slowing for a light and a compact hit me at at 50mph
from the rear in my 700lb EV trike pickup and unlike the one 20 yrs ago in my E
woody which only took $40 to put back on the road, the trike was totaled.Again
good engineering using my rear tires as a crash load
Thanks Jerry for your practical use of parallel pack info using Volt
batts! Bummer on the trike - glad you are ok! Did you just use a fixed
charge connected to all the packs , no diodes or contactors? It seems more
ppl are using Volt packs without any BMS than those that use one. I'm going
