Questions answered on the product page

How do I choose the correct BMS for my battery?
Provide the chemistry, exact series count, continuous charge and discharge current, and peak current with its duration. Then check balancing current, installation space, cooling, inverter, hardware revision and matched wiring. Nominal voltage, a series name or a similar connector alone does not establish compatibility.

Can I add a 4.3-inch display and WiFi module to this BMS?
Yes. The current catalogue offers these options for this BMS, independently or together. Each selected accessory is supplied once per BMS; a display already included in the selected package is not charged twice. Confirm the adapter and harness for the supplied hardware revision.

Do two selected accessories give a 10% discount?
No. Selecting a display or WiFi applies the 5% discount once to the BMS and those accessories. Two accessories do not double the discount. H/C/R feature fees do not trigger or receive the discount and are added in full afterwards.

Can this BMS be ordered with a 7-inch display?
The 7-inch display option is limited to the PB series and is not offered for this BMS. Use the display choices listed on this page and confirm the adapter and harness.

Can I add heating, CAN and RS485, and what do they cost?
H means heating interface, C means CAN and R means RS485. All PB-series models and B2A32S-RP include CAN and RS485 as standard: no selection or extra charge is needed. Each feature not already included costs USD 1 per BMS. Features included in the model are not offered or charged again. The final model retains existing feature letters and adds only newly selected options in H, C, R order, preserving any existing PB suffix. Option fees are added after any 5% bundle discount and do not trigger it. Confirm the model, hardware revision, application protocol and harness for your inverter.

Does CAN or RS485 guarantee compatibility with my inverter?
No. Confirm the exact inverter and BMS models, hardware revision, application protocol, firmware, pinout, cable and settings. A website selection or a matching connector does not prove that the two devices can communicate.

Before purchase
- Prices and availability are retrieved from the current published store data. Recheck the selected package and destination before payment. Inventory snapshots are not stock reservations.
- Technical evidence is configuration-specific. A merchant-confirmed current-batch fact is not an exact-model manual, and a nearby model does not establish compatibility.
- Product-family photographs do not verify exact SKU appearance. Internal store SKUs are not GTIN or EAN barcodes.
- Purchases complete on the JKBMS website. This document does not establish any AI-platform approval, formal feed distribution or native payment integration.
