Operation and construction - Capacitive energy transfer drives the balancing; the equalizer board connects to the battery to start balancing. Uses brand-new ultra-low-resistance MOSFETs and a 2 oz copper-thickness PCB. Compensation range 0-5.5 A. Capacitive energy transfer card - High-accuracy 5 mV, balances the whole cell group, including non-adjacent cells. Operating voltage and compatibility - Operating input voltage 1.8 V to 4.5 V. Suitable for lithium ternary, lithium iron phosphate, and lithium titanate chemistries. Performance and quiescent current - The more cells in the pack, the better the balance. Wiring position reserved for the resting switch. Off-state current less than 0.1 mA. Compensation voltage accuracy 5 mV. Active balance and energy transfer - Energy transfer card for active balancing of lithium batteries. Active equalizer with high-efficiency energy transfer.
