- JKBMS JK-B2A25S-CR60P product specification V23.0.1 (2026-09-17) (V23.0.1)
The specification lists maximum and instantaneous figures, not a continuous duty rating. Busbars, terminals, fusing, cooling and cells must support the intended current.
Manual data is revision-specific. Confirm the shipped label and harness before wiring.
HARDWARE SPECIFICATIONS
JK-B2A25S-CR60P data by hardware revision
The V23.0.1 specification maps JK-B2A25S-CR60P to 7-25S ternary, 8-25S LiFePO4 and 14-25S LTO packs, lists 600 A maximum charge and discharge current with a 1000 A instantaneous figure, 2 A active balancing, a 20-110 V supply range and a 10 A heating circuit, and defines Bluetooth, UART, RS485 and CAN on fixed connectors.

Interfaces and functions
Standard is not the same as optional
Standard
Bluetooth · UART · RS485 · CAN · display interface
Additional standard functions
2 A active balancing · Charge overvoltage and overcurrent protection · Discharge undervoltage and overcurrent protection · Charge and discharge over-temperature protection · Low-temperature charge protection · 10 A battery heating circuit · Alarm output · Discharge pre-charge · Emergency switch · Intelligent sleep · ACC / charger detection · Two dry-contact channels
- V23.0.1 defines RS485 and CAN on the fixed four-pin P7 communication connector, so both signal pairs are present on the board; the protocol and address are set in the app.
- A physical CAN or RS485 port does not by itself confirm inverter protocol compatibility.
- The display interface is standard; the screen itself is a separate option.

Revision control matters.
- V23.0.1 is dated 2026-09-17 and is the revision this listing was written from; confirm the label on the board that ships.
- The specification gives 600 A as the maximum charge and discharge figure and 1000 A as the instantaneous figure; it does not publish a continuous current class.
- Balancing starts at 3 V / 3 V / 2 V and the 2 A balance current is the default and adjustable in the app against pack capacity.

Before ordering
Four details that prevent the wrong configuration
- Confirm battery chemistry and the exact string count within 7-25S ternary, 8-25S LiFePO4 or 14-25S LTO.
- Confirm the sustained charge and discharge duty; 600 A is a maximum, not a continuous rating.
- State whether heating, alarm output, dry contact or ACC / charger detection is required in the order.
- Provide the inverter brand, model and protocol before relying on CAN or RS485.
- Size heating wiring at 16 AWG or larger and series a 45-65 °C normally closed thermal switch as secondary protection.

Product FAQ
JK-B2A25S-CR60P compatibility, configuration and purchase FAQQuestions & answers
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.
Which cell counts does JK-B2A25S-CR60P support by chemistry?
V23.0.1 lists 7-25S for ternary lithium, 8-25S for LiFePO4 and 14-25S for LTO, so the usable lower limit depends on the chemistry you select in the app.
Is 600 A the continuous current for JK-B2A25S-CR60P?
No. The specification lists 600 A as the maximum charge and maximum discharge current and 1000 A as the instantaneous current, and publishes no continuous class. Conductors, terminals, fusing, cells and cooling must be rated for the real duty.
Are CAN and RS485 fitted on JK-B2A25S-CR60P?
V23.0.1 defines both signal pairs on the fixed four-pin P7 communication connector, so the hardware carries them. Address and protocol are configured in the app, and inverter protocol compatibility still needs the inverter brand, model and protocol confirmed.
What does the heating circuit on JK-B2A25S-CR60P need?
The manual designs the heating circuit for 10 A, recommends heating wire of 16 AWG or larger, and advises wiring a normally closed 45-65 °C thermal switch in series as a secondary cut-out against thermal runaway.
