Заказ пришел за 2 недели. Заказывал две штуки. Один для работы один про запас. Штука простая, но очень полезная. Выставляешь пороговое напряжение от 2,7 вольт подключаешь к балансировочному разъему и вперед. Как только напряжение одной из банок сравняется с выбранным значением сигнализатор начинает бешено пищать. Короче штука мне понравилась. проста и без наворотов лишних. Советую к покупке. Если отзыв оказался полезен нажмите да.

заказал 2 шт. Как пришли, сразу проверил. Обе работают, пищат громко, напряжение показывают правильно, пищалка работает на 2 банках и более. на 1 банке просто показывает напряжение. поставил срабатывание на 3,2В - посадить самолетик вполне хватает
