I'm hoping someone may be able to tell me why it is that on the Mtronics website, the only ESC suitable for a lipo battery is the 'TIO', yet two friends of mine are curently running lipo's with normal 25 and 40 amp Mtronics ESC's with no problems. My question therefor is....Can I or can I not run lipo's with these ESC's. I await any replies with interest. Thanks in advance

The TIO has a safety low battery voltage cut-off for LIPO batteries whereas the Viper 15 does not have this facility. If you are confident in not running down your LIPO battery to below a 'safe limit' then you should be OK to just use the ordinary Viper.

Basically ads is correct, but that's only half the story!
The clue is to look for 'LiPo Safe' when buying ESCs.
That tells you it has a programmable Cut Off voltage setting to prevent damage to your battery. Default is usually 3.2V per cell.
Absolute minimum is 3.0V. Below that you risk irreversible damage to the battery due to chemical changes that can't be reversed.

The alternative is to fit a battery monitor which can trigger an audio and/or visual alarm to warn you to 'make nearest port best speed' before your battery is deep discharged, from which it will not recover!
Some ESCs have a programmable function which allows to preset a reduction of the max power to the motor (instead of a total shut down) to give you the chance to get home before disaster.
PLEASE don't ask me which ones. Check the specs carefully before you buy.
Many current TX/RX sets will tell you on the TX display when the battery volts are low.

Thanks for your advice. I already have 3 boats with Mtronics Viper ESC's, and I didn't want to change them if it wasn't necessary.
