2S-12S LiPo & LiFe battery Monitor and Saver BS12 V2.3
www.chargery.com page 2 total 6
Chargery Battery Saver BS12 is the first up to 12S LiPo & LiFe battery saver with TFT color LCD applied
to helicopter; High light red LED and two loud beepers (100Db min.) make sure your flight safety.
The warning voltage, delay time and warning time can be setup by pressing easily the button.
Large TFT colorful LCD can display each cell voltage and total voltage. During battery discharge, it
can sound and LED flash alternately while any cell voltage under setup value, prevent any cell from
over discharged. Even you can check the lowest cell voltage after your helicopter land off, so you can
find the worst cell---the lowest voltage cell.
V2.1 Update note
Add a telemeter port to connect to the receiver, when any warning events happen, the transmitter can
sense the warning events.
When start warning the telemeter port will output 5V, if no warning, it will be 0V.
V2.2 update note
Add a jump port to connect the socket 1 and socket 2, it is for two packs without any connection. If
two packs connected in series or parallel by discharge cable, the jump port must be open.
V2.3 update note
Loudly Beeper, 100dB min. at 12V
TELEMETER port renamed as BPG (Battery Pack Good)
New features
 From BS12 V2.0, two packs can be connected in series or in parallel, the device can identify the
connection automatically and monitor each cell voltage accurately.
 Over charge voltage can be programmed from 3.00~4.30V
 Over discharge voltage can be programmed from 2.00~4.00V
 Wait time can be programmed from 0.0~20S
 Alarm time can be programmed from 1.0~60s
 LCD Back-light time can be programmed from 1min, 5min, 10min, 20min and always on.
 BS12 can record the lowest voltage of each cell including total pack voltage during flight, after
your helicopter land off, you can press UP/DOWN to display these voltage (cell number
background color change, and cell voltage displayed in RED text), press the button again
display real voltage.
 Beeper sound and LED flash alarm while any cell over charged or over discharged.
 At any time, you can press SET button shortly turn off the display and press again resume.
 While alarming, press SET button shortly turn off alarm at any time.

Operating guideline
1. Connect the battery to BS12, keep the polarity correct. The detailed connection diagram is as the
following figure 1, figure 2 and figure 3.
2. The Device will initialize the beeper and LED, beeper sounds once time, warning LED flash once
time.
3. 2 seconds later, the BS12 will display the cell count, total voltage on the top line, and warning
voltage, delay time, warning time on the bottom line from left to right. The middle area, each cell
voltage is displayed. When any cell voltage reaches the dynamic lowest value, it is displayed in
RED color, the lowest voltage will be updated with the value changes.
4. At any time, you can press SET button shortly turn off the display and press again resume. If the
back-light time is always on, it is invalid.
5. While alarming, press SET button shortly turn off alarm at any time.
In flight, BS12 can alarm loudly and a large WARNING RED LED flash when any cell voltage under
setup value till the cell voltage over warning voltage.
If the cell voltage is still under warning voltage, the unit will beep and flash repeat for the warning
time.
The unit includes reverse polarity detection, and 2.54mm pin distance balance connector for all kinds
of battery.

Program setup
Before flight, you can enter into Program setup menu, and set up the parameter according to your
need such as over charge voltage, LCD back-light time etc.
1. Connect 2S (LiPo 7.4V, LiFe 6.4V) or under 6S
battery to the socket 1.
2. Press SET button for 3 seconds enter into
Program Setup menu.
3. Press UP/DOWN button select the item, press
SET shortly make the value flash, and press UP
/ DOWN change the value. Press SET button
