Frequently Asked Questions - BPH A72T-18+3A PowerPlus

How do I install the battery pack?

Follow the SOP: serial connect all 18 batteries using wires with tubes. Ensure batteries have the same date code and capacity. Tighten screws to 8 KGF-CM torque. Refer to the manual for detailed steps.

What type of batteries should I use?

Use 12V/7Ah or 12V/9Ah sealed lead-acid batteries. All batteries must have the same date code and capacity. Do not mix different types or capacities.

What is the total voltage of the pack?

With 18 batteries in series, the total voltage is 216 V (18 x 12 V).

How often should I recharge the pack when not in use?

Recharge every 2-3 months if unused. For storage temperatures between 40-45°C, recharge every 2 months. Follow the recharge duration of 1-2 hours.

What safety precautions should I take?

Remove metal objects, use insulated tools, wear rubber gloves and boots. Do not short circuit terminals. Disconnect charging source before connecting or disconnecting batteries. Do not block ventilation openings.

Can I use batteries with different capacities?

No, all batteries must have the same capacity (e.g., all 9Ah). Mixing capacities can cause imbalance and reduce performance. Replace all batteries at once.

What is the expected battery life?

The battery life is 3-5 years at 25°C ambient temperature. Higher temperatures may shorten life. If the batteries exceed this life, they must be replaced.

How should I store the battery pack?

Store the unit covered and upright in a cool, dry location. Temperature range: -25°C to 45°C. Recharge according to the storage schedule to avoid damage.

What tools are needed for assembly?

You need an electric screwdriver, crosshead screwdriver, and nipper. Use M3*6 flat-head and round-head screws with a torque of 8 KGF-CM.

What voids the warranty?

The warranty is void if batteries fail due to overheating, exposure to water or foreign objects, improper storage, or failure to recharge every 2-3 months when unused. Also, using batteries with different date codes or capacities voids warranty.

SOP – How to assemble Battery Pack with 18 batteries (BP A72T-18x9Ah+3A)

1. As shown, please use all batteries (12V/7Ah or 12V/9Ah) with the same date code. (CAUTION: it's necessary to use tubes for red wires).

NOTE: This will prevent short circuit from direct contact of terminal.

1. As shown, serial connect batteries (12V/7Ah or 12V/9Ah) with wires one by one. (It's necessary to insert black wires into tubes)

2. As shown, serial connect two batteries as a set. Install one set on the right hand side with battery terminal facing front panel. (put the battery with red wire on the bottom and keep the terminal on the upwards; the top one with the terminal on the bottom side.)

3. Then install the other two sets (As shown on the left chart, install the left one set and then the middle one set)

4. As shown, connect black wire of the top battery in the middle set to the top battery on the right set. Put the black wire under the battery divider.

Tool: nipper.

CAUTION: 1. Use batteries with the same date code in the same UPS. 2. Do not direct connect battery terminal and metal to avoid short circuit. 3. Connect wires correctly and tightly. Do not miss tubes.

1. As show, screw short dividers tightly to main column with 6 screws. M3*6 flat-head screws. Torque: 8KGF-CM
2. Let two red and black wires pass through divider as shown.

1. As shown, when black and red wires pass through divider, take off the tubes and plug black wire to P7 of small board. Plug red wire to P7 of small board located on the bottom.
2. Use one long black wire to connect to P8 and one short black wire to connect to P9. Use one long red wire to connect to P2 and one short red wire to connect to P3 of small board located on the bottom.

Tool: electric screwdriver, crosshead screwdriver, nipper

CAUTION:1. All screws should be screwed tightly and do not missing. 2. Connect wires correctly and tightly.

1. As shown, connect batteries (12V7Ah or 12V9Ah) one by one.

2. Screw two battery dividers tightly to main column. (NOTE: there are two round-head screws located on the back panel) M3* 6 round-head screws Torque: 8KGF-CM

3. Serial connection all batteries with wires one by one.

Tool: electric screwdriver, crosshead screwdriver, nipper CAUTION:

1. Do NOT directly contact with battery terminal and metal during installation. Otherwise, it will cause short circuit.
