Low Voltage cut out for LRP Sphere
 

I have inherited an LRP sphere ESC. Seems to work fine, but I am worried that as it is a few years old, it doesn't seem to have a low voltage cut out to make it safe for use with LiPo saddle packs.
Can anyone advise how I install a separate cut off. I've heard talk about them, but not really sure what the are. Are these available? Would I be better getting a new ESC?

If you are only racing for 5 minutes, the chances are you won't come close to the low voltage, especially if you are running 2wd.

However, these are available:

They solder to the battery side of the ESC and plug in line with the reciever and esc signal wires that would normally be plugged into the esc (hence the 2 receiver wires, one is a plug, one is a socket).

When the voltage gets too low, they pulse the throttle and flash an led. If the voltage gets really low, the cut the throttle completely.

At around a third of the cost of a reasonable esc whether it's worth it is up to you.

That's great. Thank you

Unless it is the older Sphere, with reverse, you should have a low-voltage cutoff.

As above.... I run both standard and tc Spheres... They do have low voltage cut off, no problem with lipos, and are a very good esc.. You should have no problems...

I've turned my LVC off.
Just have a timer set on my Tx. Have it set to 8 mins (4wd) 10 mins (2wd) and 12mins (TC). Batteries usually come off at 7.75v, give or take.
So if i do run for an extra couple of minutes after the timer buzzes me, no big deal.

That's a great idea. Thanks
