V19.0.3 maps the 20P model to 200 A maximum continuous, charge and discharge current. For V24.0.1 hardware, keep 200 A as the model class and confirm the configured protection limits.
Manual data is revision-specific. Confirm the shipped label and harness before wiring.

Product overview
HARDWARE SPECIFICATIONS
JK-PB2A16S20P data by hardware revision
The V19.0.3 manual explicitly maps JK-PB2A16S20P to the 200 A current tier, while V24.0.1 verifies the chemistry-specific cell counts, 2 A active balancing, standard interfaces and V24 enclosure. Match the hardware revision before wiring.
Electrical limits
Use the correct rating label
- Active balance
- 2 A
- Current class
- 200 A
- Supply voltage
- 20–80 V
V19.0.3 maps the 20P model to 200 A maximum continuous, charge and discharge current. For V24.0.1 hardware, keep 200 A as the model class and confirm the configured protection limits.
Interfaces and functions
Standard is not the same as optional
Standard
Bluetooth · CAN · RS485-1 · RS485-2 · display interface
Additional standard functions
Heating control · Two dry-contact outputs · Parallel current limiting · Discharge precharge
- CAN and RS485-1 are provided for inverter communication.
- RS485-2 is used for parallel communication or PC software.
- Protocol compatibility, cable pinout and inverter settings must be confirmed for the target system.

Revision control matters.
- V19.0.3 explicitly maps JK-PB2A16S-20P to 200 A maximum continuous, charge and discharge current.
- V24.0.1 lists 100 A, 150 A and 200 A tiers; confirm the shipped label and configured limits before relying on a protection setting.
- V19 and V24 wiring, connectors and harnesses must not be mixed by assumption.
- The available documents do not establish that V24 replaces every V19 unit.
- Weight, operating-power value and disputed instantaneous-current values are intentionally not published here pending final adjudication.

JK-PB2A16S20P: 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?
Sì. Questa pagina appartiene alla serie PB, per la quale è prevista l’opzione da 7 pollici. Verifica adattatore, revisione e contenuto del pacchetto prima dell’ordine.
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.
