General Description
Thanks for choosing TBB product.
The BML series battery monitor features microprocessor controlled combined with high
resolution measuring system for lithium battery voltage and charge/discharge current . With
built in software, BML series can calculated consumed AH/KWH and remaining AH/KWH, and
display battery voltage and battery current as well.
BML could record all battery activities since the first installation (max 200 records). Apart from
discharging and charging, multiple other factors are considered including battery size, age ratio
of battery etc. With shunt, even the smallest leakage current can be detected and recorded to
guarantee the accuracy.
Compared with conventional indicating meters, small current can be measured and read exactly
with this device. With this feature, latent consumers (insulation fault, wrong connections,
standby unit etc) can be recognized immediately. Meantime, through additional sensor second
battery voltage can be measured and displayed.
With the optional DOD protection unit, battery low voltage protection level can be programmed
and alarm cam will be sent once reaching the limit to avoid battery damage due to deep
discharge. In the meantime, it can be used to drive the battery protection device to shut off the
battery against further discharge.
Battery voltage of service battery
Each Cell voltage of the lithium battery
Battery current : charging and discharging
Battery residual capacity in AH
Battery capacity in %
Programmable for protection point
RS485 is available
Available model: 100A, 200A and 400A.

Cable-Flex-50/30 or Cable-Flex-25/30
Cable-Flex-50/30 and Cable-Flex-25/30 are to connect between battery negative connector and
BAT- connector of current detector module (SS or SH).
Installation Request
Work temperature: -20～60℃
Storage temperature:-40～85℃
Cooling: Natural cooling
Humility: 0%-95% non-condensing
Install the unit at the location where has well ventilation.
Recommended working temperature is 0～25℃
Recommended humility is around 50%
Installation
Professional electrical technician is required for the installation.
Please make sure BML is powered off during the installation which means the connection
between Cable-BM/03 and Cable-Starter-Batt-Volt/01 BAT+ / Cable-Service-Batt-Volt/01 S-BAT+ is
the last step of the installation.
Please make sure all of the equipments are powered off during the installation.
The location of SS/SH is recommended to be as close as possible to the battery. Shorter cable
between SS/SH and battery is better.

Operation
First power on
1. Confirm the connections are correct as the manual guided and fastened.
2. Connect Cable-Starter-Batt- Volt/01and Cable-BM/03.
3. Connect Cable-Service-Batt-Volt/01 and Cable-BM/03.
BML is powered on after the above steps.
4. Initial settings for BML.
a) Set battery type and capacity.
b) Set System datetime and installation datetime.
c) Battery capacity correction. Use a proper battery charger to charge the battery until
there is no alarms on the BML display.
d) Any change of the battery type or battery capacity setting needs a repeat for step b)
and c)
DO NOT plug out any connectors on the BML during it is working.
Power Off
a) If there is starter battery connected, disconnect the cable connect with the
starter battery first, then disconnect the cable connected to the service
battery,Cable-Service-Batt-Volt/01 and Cable-BM/03 to complete the shut down
of BML.
b) If there is no starter battery connected, disconnect disconnect the cable
connected to the service battery, Cable-Service-Batt-Volt/01 and Cable-BM/03 to
complete the shut down of BML.
