Anyone having trouble with their batteries in the Earthquake, we have been losing batteries and I think the ESC is to blame, probably the low voltage cutout is too low.

My brother lost 1 LiPo on his Earthquake.

How would you check it?

the ezrun ESC's can be set with the radio(you can find the how to online) but its a pain.
You can get the ESC program card off ebay. just plug the ESC into the box, turn it on and its really easy to set all settings.
the LVC is adjustable from 2.9-3.6 or something like that.
if its set low, and the lipos are not well balanced then a cell will dip below safe levels.

I was having a similair problem for a while as well. It would drain one normal (I guess you can call it that) and the other would be drained to the point where my charger would not charge it.
I went though many batteries.

I contacted redcat about it and they asked me to ship my esc to them for them to test it. They sent me a brand new one.

any time you have an RC that runs 2 batts in series, its important for both packs to be equal in voltage and balance.
if they arent, then one pack will get drained lower before the LVC kicks in.
This is cause the LVC reads total voltage, not the voltage of each pack.
if the LVC is set at 3.0v, then it wont kick in till it reads 12v from the 2 packs. so, one pack can be putting out 7v while the other is being drained to just 5v.
Balance charging both packs is very important when running them in series.
i have the ESC/motor and lipos from my earthquake(sold the chassis) and im running them in a e-savage(tho the driveshafts have a hard time with all the power)
neither the ESC or lipos have given me any issue.
