2022 Good Quality 12 Volt Bms Module - DALY Pack parallel BMS matching instructions(15A) – Daly

DALY PACK Parallel BMS

Pack Parallel Module+BMS=Pack Parallel BMS
Realize safe parallel connection of lithium battery pack.Suitable for Li-ion 3S/LifePo4 4S/30A-60A BMS, and 5A PACK Parallel BMS.

More power in safe parallel

Active balancing technology allows the same type of lithium battery packs with the same number of series to safely connect more power in parallel.

Avoid high current shock

 Limit the Max charging current, effectively prevent high-voltage battery pack charge to low-voltage battery pack by high current shocks.

Bluetooth Smart Communication

Connect the BMS through the mobile phone Blue-tooth APP, monitor the battery data in real time, and set the relevant parameter values (monomer voltage, total voltage, temperature, power, alarm information, charge and discharge switch, etc.).

Intelligent Control Of Parallel Battery Packs

Through communication protocol and external components, the running data of parallel battery pack can be presented to the display device in real time, and related parameters can be viewed or set.

Precharge Resistor Optimized Power-on Sequence

BMS is equipped with a precharge resistor to pr-event the power-on current from being too large and short-circuit, and prevent the BMS from being damaged by the super capacitor.

Unique TVS

Prevent high pressure shock
The unique TVS realizes faster over-voltage protection, effectively clamps the surge voltage, prevents reverse voltage from impacting the MOS, and makes the overall performance of the BMS reliable and strong.

PACK parallel BMS wiring diagram

Please select the corresponding wiring method according to the purchased model.
Wiring method of 1A parallel module.
The 1A parallel protector has only one wire outlet, and there are 5 wires in total. It is only necessary to combine the 5 wires and connect them to the corresponding DO port of the BMS.

PACK parallel battery pack wiring diagram

1.PACK parallel protective board consists of two parts:

The BMS+parallel protector,that is,each PACK that needs parallel. The two must be included.

2.The detailed wiring method of the protective board view the wiring map of the protective board.

3.Wiring Precautions

Method 1

(the BMS and the parallel BMS module wire are not connected):After the BMS is assembled, when the parallel BMS module is connected to the BMS, first connect the parallel BMS modules P-wire to the BMS (the common port is connected to the BMS P-wire, and the separate port is connected to the BMS C- wire), and then connect B-and B+ in turn.After the wire is connected,first plug the BMS and parallel BMS module ports, then the B+ port, and plug the control signal wire to the protection board finally

Method 2

(BMS and parallel BMS module lines are connected): first plug the BMS and parallel BMS module ports, then plug into the B+ port, and finally plug into the control signal line to the BMS;

※Please strictly follow the above two methods for wiring, please operate in sequence if the wiring sequence is reversing, it will cause damage to the parallel BMS module.

4.The BMS and parallel BMS modules must be used together and can’t be mixed using. Wiring should be done according to the purc-hased parallel BMS module corresponding to the current.
