Battery Voltage Settings

So I've just been working on the motor drivers and I did my first serious speed and power tests using the mobile vesc tool app, and I've been using it and its been really helpful with speed and power limiting and it goes plenty fast downhill and on flat ground, but as soon as I go uphill, the voltage drops really low, which understand is normal, but I don't know what kind of settings I should have to counter this, below are my significant settings

Setup    10S2P 4AH Battery Meepo V3 Battery Li-ion, 2x 540 watt hub motors, 2FSESC 4.20 Pluses

Battery Voltage Cutoff Start 10v

Battery Voltage Cutoff end 8v

Speed Forward Limit 30 mph

Current Accel 90%

Current brake 100%

Max power out 800 watt

Max power Regen -500 watt

Motor Current Max 50 A

Motor Current Max Brake -25 A

Absolute Max Current 135 A

Max Current Scale 89%

Min Current Scale 100%

Battery Current Max 27 A

Battery Current Regen Max - 15 A

the battery pack u have will suffice for casual riding for those 2 motors. it does not have enough continuous output amparage  for max throttle or going uphill. this is why u see big voltage dropdown. voltage drop is normal

Dude, your battery cutoff's they're seriously way too low!

10s battery pack

Each cell shouldn't go below 3.0v ever! 

3.0×10=30.0v

I have my battery voltage cutoff's at

34.0 start

31.5 end

I run a 10s2p

Yo be careful, I have almost the same setup as you and I fried one of my motors yesterday. Granted, I knew it could happen and I absolutely maxed out everrrrything lol. I'm actually surprised how much torque and speed I was able to get with the meepo motors. (for ~20 minutes or so until one of the motors started gurgling lol)
