JK-PB2A16S20P is a 200 A-class energy-storage BMS for 7-16S Li-ion, 8-16S LiFePO4 or 14-16S LTO packs. V19.0.3 explicitly maps the 20P model to 200 A maximum continuous, charge and discharge current. V24.0.1 verifies 2 A active balancing, Bluetooth, CAN, dual RS485, a display interface, heating control, dry contacts, parallel current limiting and discharge precharge. Confirm the hardware revision, protocol and harness before ordering.

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?
Yes. This page belongs to the PB series, which offers the 7-inch display option. Confirm the adapter, revision and selected package before ordering.

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.

Which battery cell counts does JK-PB2A16S20P support?
The V24.0.1 manual lists 7-16S for ternary/NMC lithium, 8-16S for LiFePO4 and 14-16S for LTO. Select by chemistry as well as series count.

Are CAN and RS485 standard on JK-PB2A16S20P V24?
For the V24.0.1 configuration, Bluetooth, CAN, two RS485 channels and a display interface are listed as standard. CAN and RS485-1 serve inverter communication; RS485-2 serves parallel communication or PC software. Protocol and cable compatibility still require confirmation.

What does the 200 A rating mean for JK-PB2A16S20P?
The V19.0.3 manual maps the 20P model to 200 A maximum continuous, charge and discharge current. For V24.0.1 hardware, treat 200 A as the model class and confirm the configured protection limits and complete system design.

Can a V19 harness be reused on a V24 JK-PB2A16S20P?
Do not assume so. V19 and V24 connectors, wiring and harness definitions must be matched to the actual hardware revision before connection.

What size is the JK-PB2A16S20P V24 enclosure?
The V24.0.1 manual gives 300 × 100 × 24 mm. Confirm the label because this dimension is revision-specific.

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.
