    Pros: - Battery level meter - On/off button - USB connector Cons: - With some bike light it can flicker - Not so good water resistant (rubber ring needs to replace)

    This is a great idea for packing 4 x 18650 batteries to create a battery pack. Very useful for providing autonomous power to a bike light, for examp Cons: 1) Not waterproof. There is a rubber-like seal but it is not thick enough to provide reliable watertightness. A round opening with an O ring would likely have been necessary to ensure proper protection against water. So the BC-02 would be practically useful in rain. 2) The USB connector which allows it to serve as a power pack for cellphones,

    Отправили на 4 день. Приехал всего за 8 дней, это рекорд для недорогих посылок. USB порт отлично держит 2А (проверял на резисторе), просадка напряжения небольшая. Герметичность пока не проверял.

    Good quality pack for my solar storm bike lights, Nice to be able to use your own decent quality battery’s. My only complaint would be the USB port which doesn’t have a waterproof cover as we get a fair bit of rain.

    Покупал в первую очередь для велофары, результат лучше ожиданий: с хорошими 18650 аккумуляторами (2600 мАч) фара светит почти в два раза дольше чем с той аккумуляторной сборкой, что шла в комплекте к фаре. Так же радует, что можно менять аккумуляторы, когда те разрядятся, а севшие потом

    Very good build quality and electronics, the USB output voltage (unloaded 5v) dropped slightly to about 4.5v at around 1.9A load when i tested it, the 5.5mm socket is permanently powered and the usb output is powered by the switch, which also shows state of charge by 3 tiny green leds which are permanently lit when the usb is powered on. The top fits the holder well and a decent quality o-ring seals the unit from moisture ingress, although it wont provide full waterproof safety it is rated ipx4 (which

    I got the replacement unit today. have to say it's brilliant. Would recommend it to anyone who is looking for a unit to charge his 18650's, use it as a powerbank or hook up a bike light. Next test will be to use it as intermediate between a solar panel and a phone. Anyway, definately worth the hassle, eventhough I got a broken unit at first, banggood service is great they replaced it right away. You guys rock. I'll use banggood anytime before even looking at ali, the extra cost is so worth it when

    Good case. Had to modify the case because of the bottom contacts only one side was working. Used four fully charged 18650 batteries for one hour check volts after use and two were at 3.86 and the other two were still at the same charges volts of 4.17. Fixed with new contact metal bases and a wire to connect both metal bases together. Now all batteries after use have the same volts reading, Perfect fix.
