Product overview
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.
Electrical limits
Use the correct rating label
- Active balance
- 2 A
- Maximum charge
- 600 A
- Maximum discharge
- 600 A
- Instantaneous current
- 1000 A
- Supply voltage
- 20–110 V
- Cell-voltage accuracy
- ±3 mV
The specification lists maximum and instantaneous figures, not a continuous duty rating. Busbars, terminals, fusing, cooling and cells must support the intended current.
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.
Mechanical and environment
Match dimensions to the label

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.

Domande sul prodotto
JK-B2A25S-CR60P: compatibilità, configurazione e acquistoDomande e risposte
Come scelgo il BMS corretto per la mia batteria?
Specifica chimica, numero esatto di celle in serie, corrente continua di carica e scarica e picchi con la loro durata. Poi verifica corrente di bilanciamento, spazio, dissipazione, inverter, revisione hardware e cablaggio. Non dedurre la compatibilità dalla sola tensione nominale, dal nome della serie o dall’aspetto del connettore.
Posso aggiungere lo schermo da 4,3 pollici e il modulo WiFi?
Sì. Nel catalogo attuale sono disponibili come opzioni per questo BMS: puoi sceglierne una o entrambe. Ogni accessorio selezionato viene fornito nella quantità di uno per BMS; uno schermo già incluso nel pacchetto selezionato non viene addebitato due volte. Verifica comunque adattatore e cablaggio della revisione fornita.
Se scelgo due accessori, lo sconto diventa del 10%?
No. Selezionando uno schermo o il modulo WiFi, lo sconto è del 5% una sola volta sul BMS e su questi accessori. Due accessori non raddoppiano lo sconto. I costi H/C/R non attivano lo sconto e vengono aggiunti interamente dopo lo sconto.
Questo BMS può essere ordinato con lo schermo da 7 pollici?
L’opzione da 7 pollici è riservata alla serie PB e non è offerta per questo BMS. Usa le opzioni di schermo indicate su questa pagina e verifica adattatore e cablaggio.
Posso aggiungere riscaldamento, CAN e RS485 e quanto costano?
H indica l’interfaccia di riscaldamento, C indica CAN e R indica RS485. Tutti i modelli della serie PB e il B2A32S-RP includono CAN e RS485 di serie: non occorre selezionarli e non vengono addebitati. Ogni funzione non inclusa costa USD 1 per BMS. Le funzioni già incluse nel modello non vengono offerte né addebitate di nuovo. Il modello finale conserva le lettere esistenti e aggiunge solo quelle delle nuove opzioni, nell’ordine H, C, R, conservando l’eventuale suffisso PB. I costi delle opzioni si aggiungono dopo l’eventuale sconto del 5% e non lo attivano. Verifica modello, revisione, protocollo applicativo e cablaggio per il tuo inverter.
La presenza di CAN o RS485 garantisce la compatibilità con il mio inverter?
No. Occorre verificare il modello preciso dell’inverter e del BMS, la revisione hardware, il protocollo applicativo, il firmware, la piedinatura, il cavo e le impostazioni. Una scelta sul sito o un connettore simile non dimostrano che i due dispositivi possano comunicare.
