I tend to use wires with small crocodile clips on each end, then attach the other end to the battery using a couple of small magnets. **Q: Can input voltages below 5V be used? like small solar panel** A: You really need the full 5.0v to make full use of this battery charging device. It will deliver to the battery 4.2v so if you are going to be below that voltage it simply wont work. **Q: can I charge my batteries in series or only single cells** A: Single cells. Charging lithium cells in series would require a higher voltage and could be dangerous if not done right. To charge in series you want a proper bms board, they're not expensive (5 for around Β£10) and if its a 3cell 12v circuit you're working with should do the trick as it can charge each cell individually search "3s bms 12v" it requires a higher voltage input though so not usb friendly. If you want to charge from usb you'd need to charge in paralell. **Q: if the load terminals are the same as the battery terminals, how can it possibly prevent the battery from being discharged to a flat state** A: Probably by measuring the charge current. Voltage = current times resistance. ## Frequently Bought Together - AZDelivery Compatible with TP4056 Micro USB 5V 1A 18650 Lithium 3.7 V Li-Ion Battery Charging Board Module Including E-Book!
