MMM Programming help

I have some questions regarding the MMM CastleLink.

It does indeed give a hand full of features my other ESCs could not.

I notice the LVC can be set to an exact voltage to when to cutoff. If I'm running on a pair of 3S 4800 11.1V each, in a series to equal 6s 22.2V. What should I set the LVC to cut off at?

I set mine to auto lipo. This will detect the number of cells and use an appropriate value - I think it's 3.0v per cell. This is the recommended setting by Castle, though some people are more cautious and use a higher value per cell.

Same here. I switch between 2s and 3s packs, so I use the auto detection, and have run until the esc shuts down, and have had no problems. This function works very well.

Hey dock,
if your only gonna run 6S in that truck, set the LVC to 19.2, which is 3.2 per cell.
It'll help keep the lipos alive a bit longer

+1 on setting it to 3.2 volts per cell. I am only running 4s currently, so I set mine to 12.8 volts total. Nice and a littler safer for the batteries.

19.2V it is, Kudos!

much thanks for the tips guys. Im going to set auto-lipo on one of them and set 19.2 on the other, see which one drains more.

3.2 per cell is the limit? What if it breaks down to 3.1 or 3.0? Is it over after that?

3v per cell is the recommended minimum, they will survive a little lower but you don't want to go there. I use 3.2v also just to stay on the safe side...

Most people would say that you set the LVC to at least 3.2v per cell in series. so for 6s it would be 3.2x6=19.2v for the LVC. But after you run it a little bit. I think it'd be best to raise it a little if the car startes to slow down before it LVC cuts in. Your soppost to turn the car off when a lipo startes to get weak.

Whatever you do, if you want to keep the LiPo running as strong as posible for as long as posible, DO NOT let the voltage get too low or high and keep it balanced. i had a 2s lipo to get down to 5.35v and i managed to recharge it but after that, it had no punch at all and it felt like my car was on a brushed motor again
