A suitable BMS and system protection are still required for overcharge, overdischarge, overcurrent, temperature and short circuits."},{"question":"What does 5A balancing current mean?","answer":"It is the nominal balancing-current class of JK-B5A24S, not the permitted charge or discharge current of the battery pack. Actual current and correction time depend on voltage difference, settings, wiring, temperature and cell condition. It is not a promise of continuous operation at the maximum balancing current."},{"question":"How do I check whether JK-B5A24S fits my pack?","answer":"Before ordering, confirm the minimum and maximum supported series count for the hardware revision being supplied. Provide the chemistry, exact series count, cell capacity, voltage spread and existing BMS model, and verify the matched wiring and settings. Nominal pack voltage or a historical specification alone does not establish compatibility."},{"question":"Are CAN, RS485 and cascade operation included?","answer":"Do not assume they are included. Confirm the supplied hardware revision, physically available interfaces, protocol, pinout and quoted accessories. A matching connector does not establish compatibility, and support on a related model does not prove support on this one."},{"question":"Can active balancing repair a weak cell?","answer":"Balancing cannot repair a damaged cell, a loose connection, a major capacity mismatch or incorrect charger settings. Diagnose the cause of repeated imbalance first; selecting a higher balancing current does not replace that check."},{"question":"Which wiring diagram should I use?","answer":"Use only the manual and wiring diagram matched to the complete model code, hardware revision and supplied harness. Before connection, have a qualified installer verify the sampling-wire sequence and the voltages specified in that manual. Do not copy the wiring diagram of a similar-looking model."}],"links":{"product":"https://www.jkbms.net/products/jkbms-jk-b5a24s-active-balancer","text":"https://www.jkbms.net/products/jkbms-jk-b5a24s-active-balancer/facts.txt","json":"https://www.jkbms.net/commerce/catalog.json?product=jkbms-jk-b5a24s-active-balancer","catalog":"https://www.jkbms.net/commerce/catalog.json","policies":"https://www.jkbms.net/policies","contact":"https://www.jkbms.net/contact"},"notes":["Prices and availability are retrieved from the current published store data.
