Thanks for your pur hasing the Battery saver, please read the manual arefully before using.
Chargery Battery Saver BM16LF is for 3S ~ 16S LiFe battery applied to E-bike, E-s ooter et ., High
light red LED and loud beepers (85Db) make sure battery operation safety. The unit is with TFT olor
LCD display battery voltage, ell voltage, 2 battery temperature, and battery SOC (State of Charge).
You an setup over dis harge warning ell voltage, over harge warning voltage , the highest battery
temperature and the lowest battery gauge for warning.
During battery dis harge, if any ell voltage under setup value, or battery temperature over setup or
battery gauge under setup, the BM16LF an sound and LED flash alternately prevent any ell from
over dis harged.
During battery harge, if any ell voltage over setup value, or battery temperature over setup, the
BM16LF an sound and LED flash alternately prevent any ell from over harged.
In any ase, when ell voltage differen e is over setup value, the unit an alarm.
When stop driving your bike or s ooter, you an he k the lowest ell voltage, so you an find the
worst ell---the lowest voltage ell.
New features
BM16LF an indi ate battery SOC or alled battery gauge similar with ar dashboard. Cell ount,
battery pa k voltage and battery gauge (%) is displayed simultaneously.
BM16LF will re ord the lowest voltage of ea h ell during dis harge, after you stop driving your
bike, s ooter et ., you an press UP or DOWN button to display these voltages (cell number
background color is green, and the lowest cell voltage displayed in RED text), press the
button again display real voltage.
Add an alarm port to drive relay et .
Beeper sound and LED flash alarm alternately while any ell over harged or over dis harged or
out of the setup range in luding temperature SOC, differen e of ell voltage.
Two temperature sensors monitor battery temperature during harge or dis harge.
At any time, you an press SET button shortly turn off the display and press again resume.
While alarming, press SET button shortly turn off alarm.

Operating guideline
1. Conne t the battery to BM16LF, keep the polarity orre t. The detailed onne tion diagram is as
the following figure 1 and figure 2.
2. The unit will initialize the beeper and LED, beeper sounds on e time, warning LED flash on e time.
3. 2 se onds later, the BM16LF will display battery SOC (State Of Charge) as same as ar dashboard.,
two battery temperatures, ell ount, battery pa k voltage, and battery gauge in digital
per entage on the bottom line from left to right.
4. Press UP or DOWN button to he k with ea h ell voltage and lowest voltage during driving.
5. Press SET button for 3 se onds enter into Program Setup menu.
In driving, BM16LF an alarm loudly and a RED LED flash alternately when any ell voltage under over
dis harge warning voltage till the ell voltage over the value
If the ell voltage is still under warning voltage, the unit will beep and flash repeat for 20S.
The unit in ludes reverse polarity dete tion, and 2.54mm pin distan e balan e onne tor for all kinds
of battery.
