BMS EXPLAINED AND USAGE
BMS is a sensitive device therefore handle with care
BMS balances unbalanced cells
BMS protects cells from over-charge
BMS protects Cells from over-discharge
BMS protects Cells from severe cold weather conditions
BMS protects Cells from Severe hot weather conditions
BMS,if Bluetooth enabled; cell conditions can be viewed on
Mobile devices
BMS can be destroyed by faulty Balance cable wiring
REFERENCE
PROCEDURE: (TOP BALANCING) for 12V Battery.
CHECK EACH CELL voltage with DMM and note it down
Connect each Cell in PARALLEL and allow it to remain for 24 hours.
NOTE it is PARALLEL connection. THIS IS IMPORTANT to observe
.
By doing so, the cells will typically balance itself, to about 3.29V DC, thereabout.
This procedure is called TOP BALANCING.
Next remove parallel connections and recheck individual Cell Voltage and compare with initial reading.
If any of the cells exhibit low voltage, recharged it
externally to 3.29VDC.
Next connect the cells in SERIES and obtain final reading.
It should read about 12.80VDC if it is 12V battery configuration.
REFERENCE
PROCEDURE: (WIRING BMS) for 12V Battery
On LiFePo4 Cell configuration the BMS will have FIVE (5) Balance cables on a white
molex plug
.
They are one BLACK and the rest 4 white cables.
Fit Ring Terminals
to each of the cables (6.5mm or ¼” stud hole on AWG22~18 cable hole)
CAREFULLY connect BLACK cable to Battery NEGATICE Terminal.
Carefully select the next
White
cable
and connect to the next
POSITIVE Terminal and the next
White cable
to the next Positive Terminal and the next
White  cable
to the next
Positive terminal. All 4 positive terminals are connected.
OBSERVE CONNECTION CAREFULLY, ENSURE IT IS CORRECT.
DO NOT CONNECT BALANCE CABLE MOLEX PLUG TO BMS AT THIS TIME.
REFERENCE
PROCEDURE: (BMS TO BATTERY PACK)
There are two AWG10 cables on BMS
. Cable color may vary depending on makes and models. Generally it is
BLUE
and
BLACK
.
Heavy Duty LUG TERMINAL must be crimped to
BLUE BMS cable
and connect it to NEGATIVE POLE of the battery. Remember BMS BLACK BALANCE cable is also connected to Negative pole of the Battery.
Ensure tight fitting. Do not over tighten as this may lead to threads stripping.
The
AWG10 BLACK cable
is NOT connected any where.
This is the main Negative LOAD AND CHARGE CABLE.
REFERENCE
PROCEDURE: Checking final stages)
Once again ensure all connections are correct and secure.
NOW CONNECT THE BMS balance cable white Molex plug into the BMS socket.
Place DMM positive probe to Battery pack Positive terminal and Negative probe to AWG10 BLACK cable and obtain reading.
The reading should be 12.80VDC Approx.
NOW  YOU ARE READY FOR CHARGING THE BATTERY PACK. ENJOY!
(NOTE: some times this reading may be abnormal (unlikely)
Or no reading. CHECK YOUR BMS BALANCE CABE CONNECTION.
If that is correct,then TAP BMS
AWG10 BLACK
cable
to
NEGATIVE Pole of the Battery Pack. This would correct the issue if there was. Normally there is no need to perform the above procedure.)
