Lithium Battery Balance Discharge Monitoring and Protection Adapter:
Each Smart Guide / Lipo Saver Series ESC is provided with a Lithium Battery Balance Discharge Monitoring and Protection Adapter.
See LiPo Saver Series table above for the # of battery cells individually monitored by each Smart Guide / LiPo Saver model.
VERY IMPORTANT! You MUST connect the adapter with the balance charge connector on battery pack BEFORE connecting
the main power to ESC.
Programming Features Explanation:
1. Brake Settings：
：：
：Brake Enabled or Brake Disabled. Default is Brake Disabled.
2. Battery Type：
：：
：Li-xx(Li-ion or Li-poly) or Ni-xx(NiMh or Nicd). Default is Li-xx.
3. Cutoff Type (Low Voltage Protection Mode)：
：：
： Soft cutoff (Gradually reduces the output power) or Cutoff (Immediately stops output
power, also known as Hard Cutoff). Default is soft cutoff.
4. Cutoff Voltage (Low Voltage Protection Threshold)：
：：
：Low, Medium, or High. Default is Medium.
 When NOT using balance discharge monitoring and protection function (i.e. Not plugging the balance charge connector into
the balance discharge monitoring and protecting socket on the LiPo Saver Series ESCs, the ESC only monitors the voltage of the
whole battery pack )
1) For Li-xx battery, the number of battery cells is calculated automatically. Low / medium / high cutoff voltage for each cell is:
2.75V / 3.0V / 3.25V. For example: For a 3 cell LiPo, when medium cutoff voltage is set, the cutoff voltage will be: 3.0 x 3 = 9.0V.
2) For Ni-xx battery, low / medium / high cutoff voltages are 0% / 50% / 65% of the startup voltage (i.e. the initial voltage of battery
pack), and 0% means low voltage cutoff function is disabled. For example: For a 6 cell NiMH battery, fully charged voltage is
1.44 x 6 = 8.64V; when “medium” cutoff voltage is set, the cutoff voltage will be: 8.64 x 50% = 4.3V.
(Important: For the LiPo Saver Series ESCs, the low / medium / high cutoff voltage for each Ni-xx battery cell is 0% / 45% / 60%)
 When using balance discharge monitoring and protection function (i.e. Plugging the balance charge connector on the battery
pack into the balance discharge monitoring and protection socket on Smart Guide / LiPo Saver Series ESC, the ESC monitors not
only the voltage of the whole battery pack but also the voltage of each cell). For lithium batteries, low / medium / high cut off
voltage for each cell is: 2.85/3.1V/3.35V. When the voltage of any cell in battery pack is lower than the cutoff threshold, the low
voltage cutoff protection function is activated. Note: Only the Smart Guide / LiPo Saver Series provides this feature.
5. Start Mode：
：：
：Normal, Soft, or Very-Soft. Default is Normal start.
Normal is good for fixed-wing aircraft. Soft or Very-soft are good for helicopters. The initial speeds of Soft and Very-Soft mode are
very slow, usually it takes about 1 second (Soft startup) or 2 seconds (Very-Soft startup) from startup to full speed. But if throttle is
closed (throttle stick moved to bottom) and opened again (throttle stick moved up) within 3 seconds after the first startup, the
restart-up will be temporarily changed to normal mode to lesson the chances of crash caused by slow throttle response in aerobatic
flying.
6. Timing：
：：
：Low, Middle, or High. Default is Low.
In normal cases, Low timing can be used for most motors. But for high efficiency, we recommend the Low or Medium timing for
most motors. For higher speed, the High timing can be chosen.
Important: After you change the timing setting, please test your RC model on ground first!
Special Hint
Some high KV out-runner motors have very special structures, the space between each alnico is very large, and many ESCs can’t start
up these motors. After much R&D, our ESCs have shown to have very good compatibility with these types of motors. But some RC fans
still have several questions about the programming value for these special motors. Therefore, we have provided some suggestions as
follows:
Programming Value Suggestion
Motor
Timing Startup Mode
General in-runner motor Low
General out-runner motor Medium
Align 420LF (Made in TAIWAN, out-runner) High (MUST)
Aircraft use “Normal” startup mode
Helicopter use “Very-Soft” startup mode
450TH (Made in TAIWAN, out-runner) Low Soft (MUST)
Note: When this manual refers to “beep”s or music playing, it is referring to the sound emitted by the ESC.
For extremely easy programming, please consider using the Thunder Power eZ Programmer card (for details, visit our web site
at www.thunderpower-batteries.com.
Programming Example: The following 4 steps are an example of setting Start Mode to “Very Soft”. Please read and understand all 4
steps before attempting the programming. (See also Page 3 for details on setting up all Programming Features.)
1.
E
nter Programming Mode
Switch on transmitter, move throttle stick to top position, connect battery pack to ESC, wait for 2 seconds, “beep-beep” tone should
be emitted. Then wait for another 5 seconds, and a special tone like “ ”should be emitted, which means programming mode is entered.
2.
Select Items
Now you’ll hear 8 “beep” tones in loop. When a long “beeeeeep” tone is emitted, move throttle stick to bottom within 3 seconds to enter the “Start
Mode”
3.
Set Item Value
You will again hear tones in a loop as follows: “Beep”, wait for 3 seconds; “Beep-beep”, wait for another 3 seconds; then you’ll hear
“beep-beep-beep”, within 3 seconds of hearing the “beep-beep-beep”, move throttle stick to top position, then a special tone “ ” is emitted. Now
you have set the
“
Start Mode
”
item to the value of
“
Very
-
S
oft Start
”
.
4.
Exit Programming
After the
special tone “
”
,
move
throttle stick to bottom within 2 seconds.
