KEY HIGHLIGHTS || Broad battery compatibility : Works seamlessly with lithium chemistries like NCM, LiFePO₄ (LFP), and LTO. || Dynamic balancing : All cells participate simultaneously in balancing, not one at a time. When the voltage difference exceeds 0.08V, the system can pump out up to 5.5A of balancing current. || Precision control : Equalization accuracy within 5 millivolts ensures minimal voltage mismatch between cells. || Plug-and-play power : No external power supply needed—it uses the battery pack's own energy to perform its balancing act. || Tough and efficient : With a working current of just 8mA, it operates quietly and efficiently between -10°C and 60°C. || The Heltec HELTEC4S5S6S5A is a high-efficiency capacitor-driven active balancer engineered to equalize voltage among 4 to 6 series-connected lithium cells. By dynamically transferring energy from higher-voltage cells to lower-voltage ones, it effectively resolves cell imbalance issues, significantly enhancing both performance and longevity of the battery pack. || Smartly redistributes power between lithium cells with up to 5.5A active balancing current. || Heltec HELTEC4S5S6S5A Capacitor-Based Active Equalizer Balancer (4S/5S/6S, 5A) for LiFePO₄, Lipo, and LTO Lithium Batteries – Ideal for Car Audio and Group Battery Packs || Supported Battery Chemistries : NCM, LiFePO₄ (LFP), LTO || Operating Voltage Ranges : NCM/LFP: 3.0V–4.2V | LTO : 1.8V–3.0V || Voltage Balance Accuracy : ±5mV (typical) || Balancing Mode : All cells engage in simultaneous energy equalization || Balancing Current : 0.08V differential voltage = 1A equalizing current | Increases with greater voltage differences, up to 5.5A max || Quiescent Current : 8mA || Operating Temperature Range : -10°C to 60°C || Form Factor : 69mm × 69mm × 16mm || Power Source : Self-powered via internal energy transfer—no external power required || Compatible Cells Include : TBH35AHBATTERY, 34-66160-45 (batteries SOLD SEPARATELY)
