Features 1、Non‑energy consumption energy transfer type active balance board, BAL series possess zero loss mode balance 2、By detecting the unbalanced voltage difference between adjacent battery strings, the high voltage is transferred to the low voltage, and the voltage balance between the battery strings is achieved, very practical 3、Safe to use without hot. Efficient chip heat dissipation and equidistant heat dissipation layout, which can be connected to the battery pack for a long time for gradual balance 4、Daily work is not hot, fever temperature is only 27 degrees Celsius, very reliable 5、Applicable battery types are ternary lithium, lithium iron phosphate, and the number of battery strings is 24 Specification Item Type: Battery Active Balance Board Model: BAL-24S Applicable Battery Type: Ternary lithium, lithium iron phosphate Adapt to Number of Battery Strings: 24 Strings Balance Current: 1.2A (maximum) Quiescent Current of Non-Operating Unit: ≤2μA Balance Conversion Frequency: 1MHZ Balanced Transmission Efficiency: ≥92% Unit Overcurrent Protection Value: 2.3A (±0.2A) Size: Approx. 110 x 74mm / 4.3 x 2.9in Package List 1 x Battery Active Balance Board 2 x Cable 1 x User Manual
