When a set protection threshold is exceeded, the BMS can disconnect charging or discharging.<\/p>\n<p>The mobile app connects to the BMS via Bluetooth. It allows viewing the state of charge, changing protection thresholds, and checking the event history. The module also supports CAN and RS485 communication, battery heating, and precharging of the load circuit (precharge).<\/p>\n<p>The ACC input allows an external signal to enable discharging, while the CD input is used for charger detection and enabling charging.<\/p>\n<p>For this module, we recommend using original JK relays in the following versions:<\/p>\n<p><a href=\"https:\/\/onvolt.pl\/en\/products\/dc-relay-12-1000v-300a\/\" target=\"_blank\" rel=\"noopener\">Przeka\u017anik 300A<\/a><\/p>\n<p><a href=\"https:\/\/onvolt.pl\/en\/products\/dc-relay-12-1000v-500a\/\" target=\"_blank\" rel=\"noopener\">Przeka\u017anik 500A<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong>Programmable BMS module for Li-Ion, LiFePO4, LTO battery packs<\/strong><\/p>\n<p><a href=\"https:\/\/onvolt.pl\/wp-content\/uploads\/2026\/11\/ONVOLT_JK_B2A32S_RP_Manual_PL_EN_DE_CS_SK_DA_HU.pdf\">Detailed user and configuration manual<\/a><\/p>\n<p><a href=\"https:\/\/onvolt.pl\/wp-content\/uploads\/2023\/07\/Zasady-doboru-BMS-do-pakietu-akumulatorowego.pdf\">Rules for selecting a BMS for a battery pack<\/a><\/p>\n","protected":false},"featured_media":49092,"template":"","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[1902],"product_cat":[1970,2465,1971,1836],"product_tag":[],"class_list":["post-49116","product","type-product","status-publish","has-post-thumbnail","product_brand-jk-bms","product_cat-7s-24s-li-ion-uniwersalne","product_cat-7s-32s-jk","product_cat-8s-24s-lifepo4-uniwersalne","product_cat-bms-jk-en","pa_maks-ciagly-prad-rozladown-600a","pa_maksymalne-napiecie-ladowania-12-435-v-adjustable","pa_marka-jk-bms-en","pa_napiecie-akumulatora-20v-130v","pa_prad-balansowania-ogniw-2a-en","pa_typ-ogniwa-lifepo4-li-ion-lto","pa_wymiary-2346x1575x305mm","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/product\/49116","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/media\/49092"}],"wp:attachment":[{"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/media?parent=49116"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/product_brand?post=49116"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/product_cat?post=49116"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/onvolt.pl\/en\/wp-json\/wp\/v2\/product_tag?post=49116"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
