lifepo4 (Li-ion) balancer (Equalizer). Two switching thresholds. Current 2 x 1.8A (сan increase). + active balancer
Two balancers for different voltages are combined on one board. The balancing current is 2x1.8 A when using 2 Ohm load resistors. The current can be increased. The operating voltage can be adjusted by changing the divider R3-R5 (R10-R12). Can be configured to LiFePo4 or Li-ion.
The balancer is designed for installation directly on the cell. The distance between the terminals is 68 mm.
Elements U3 + C1 + C2 form a separate active balancer, with a balancing current of 20-40 mA. Installing them is not necessary.

На одной плате совмещены два балансира на разное напряжение. Ток балансировки 2х1.8 А при использовании нагрузочных резисторов 2 Ома. Ток можно увеличить. Напряжение срабатывания можно регулировать изменив делитель R3-R5 (R10-R12). Можно настроить на LiFePo4 или Li-ion.
Балансир расcчитан на установку непосредственно на ячейку. Расстояние между выводами 68 мм.
Элементы U3+C1+C2 образуют отдельный активный балансир, с током балансировки 20-40 mA. Устанавливать их не обязательно.
