I have a handful of lithium-ion batteries with very low capacities, the lowest being about 700mAh, which I wish to connect to a charging module to avoid having to physically take out of my device/project to recharge. I only have access to cheap Chinese TP4056 USB charging modules on eBay, which provide 1A current, which I have heard is dangerous to batteries smaller than that. The TP4056 modules also have 5 volts for both input and output, which is necessary for my application. How will I limit or reduce the current, if possible, to avoid damage or catastrophic failure of the battery? Is it possible to do so without lowering the voltage? Is it safe to charge these batteries at 1A? I have been unable to find any modules that go below 1A, and Adafruit/Sparkfun/Mouser etc are not accessible in my country.
The battery's device will be charged through USB and require 5V, which the TP4056 boards provide. It seems to be similar to those DIY 18650 USB power bank kits.
