Product overview
HARDWARE SPECIFICATIONS
JK-B1A8S-10P data by hardware revision
The V19.1.1 exact-model table names JK-B1A8S-10P, verifies chemistry-specific string limits, 100 A maximum charge and discharge current, 1 A active balancing, and standard Bluetooth, UART and display interfaces. Wired interfaces and heating are suffix-specific.
Electrical limits
Use the correct rating label
- Active balance
- 1 A
- Maximum charge
- 100 A
- Maximum discharge
- 100 A
- Instantaneous current
- 200 A
These are manual maximum values. Continuous current duty and complete-system conductor, fuse and thermal design require confirmation.
Interfaces and functions
Standard is not the same as optional
Standard
Bluetooth · UART · display interface
Optional / suffix-dependent
CAN · RS485 · heating control
Additional standard functions
charge overvoltage and overcurrent protection · discharge undervoltage and overcurrent protection · short-circuit protection
- CAN, RS485 and heating are defined by the exact function-selection suffix. A base model does not include every optional function.
Mechanical and environment
Match dimensions to the label
Revision control matters.
- These facts apply only to JK-B1A8S-10P V19.1.1. Confirm the shipped revision, ordered suffix, connector pinout and harness. Other model suffixes do not inherit this profile.

Before ordering
Four details that prevent the wrong configuration
- Confirm battery chemistry and exact series count.
- Confirm JK-B1A8S-10P and V19.1.1 on the shipped hardware label.
- Confirm the exact suffix and fitted communication/heating connectors.
- Confirm current duty, balancing configuration, supplied display, harness and accessory packing list.

Product FAQ
JKBMS JK-B1A8S10P Smart Active Balance BMS compatibility, configuration and purchase FAQPitanja i odgovori
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.
