Big Rock LVC didn't kick on in my BRCC??

[TraverseCity420]

Damn batteries out lasted me in the brcc and the LVC didn't kick in tested my bats each cell in my 3s pack is alarming and there 3.58 volts or less.

what gives?

ESC LVC kicks in at 3.2v

werd didn't know that thought it was 3.7, would explain the super long run times on a 6000mah lol

It's actually 3.4 volts per cell with the BLX100. The BLX185 in most of the 6s machines is 3.2 volts per cell. I would personally like to see these raised to 3.5 or 3.7 volts per cell, especially in the BLX185, but it is what it is.

Oh the downside of running rtr escs super low lvc.
I really wish that Arrma would either just run normal Hobbywing esc's or just rebrand the Hobbywing esc's and not neuter the crap out of them.

3.0 volts is the bare minimum, so you better be ready to shut off the truck quick when lvc hits, and unplug the batteries right away. I left a pair of 2s hooked in once, just threw the truck in the trunk after a bash session. It stayed in the trunk for a few days because I forgot about it, and just staying connected, drained them to 2.8 volts. Emergency defib brought them back, but having to watch them more carefully ever since. Seem to be fine with no signs of cel damage. All the cels charge back up to peak. Would be nice to find out if one of the program cards has been hacked to change the settings on the 185

The program card has nothing to do with that. It's locked in the firmware of the esc and as far as I know there is no way to unlock the firmware.

There was a thread on here a while back of someone who said they tried to use the pc link thing to flash the Hobbywing firmware to the esc and it wouldn't do anything.

So I took out my "other" truck with the almost new BLX 185, after I changed the punch to 9. Holy Pizza cutters batman! Different subject. I ran it til what I assumed was the lvc. Brought it in quick, checked the motor, right around 100 degrees, so no thermal, then checked both my 2s batteries. 3.42 per cel (give or take) across the board. If lvc is 3.2, what's going on?

The cells tend to gain a little after you turn the truck off. I wouldn't want to go lower than that anyway.

Sounds good to me. I'll start checking more often with my tester. I should have been paying more attention when I was slapping them on the charger.
