Low Voltage Warning Buzzer LED

Do these work or should I avoid this sort of thing? Does it take away the guess work? I am tempted to get one for my Mini Titan.

Absolutely! Highly recommended. I use them on all my helis. I currently have 3 on my 600EFL (1 for 2S Rx pack and 1 for each lipo). If you get the ones that work on individual cell voltage it can save your heli if a cell decides to drop off (which can and does happen!)

Yes, yes. I use ones that cost £2 delivered from China. 1-8S Lipo monitor. Batteries do get old and start to go and temperature makes a big difference as well. Mine work on individual cells which is essential, as it is always one cell that goes first. You get get them in UK as well for a higher price. You can set the volts to whatever you like. 3.7V is good for good batteries with a small volts drop under load and 3.6V for older batteries. A timer is still the main way to control discharge, but I often hit the low volts limit before the timer goes. The volts alarms give you extra information and an audible alarm is much better than losing power from the esc at the wrong time.

Yes, yes. .

Yes I thought so. Do you have a link to the ones you prefer by any chance please. I need one for my Cypher and one for my Mini Titan - the Walkera 22E won't get on. it's retired. I am used to having a voltmeter on my nitros.
