The 10180 for best reliability should be charged at one-half of rated C or about 45 mA. We have been looking at an IC that has user selectable current outputs that go down to 45 mA. The electronics provides the correct charging profile and has an overcharging limiter. The electronics is the simple part. Designing the mechanical and producing limited quantities in a cost effecent package is the hard part. Most chargers charge to 4.2 volts, however if charged to 4.1 volts the battery life as to number of charge/discharge cycles can be doubled. That is according to one of the battery manufacturers.
Is there a specific charger that you would recommend? If not, which of the following chargers would best accommodate charging 10180 cells in your opinion?
1. Belkin Charger
2. BiCha Dual lithium charger
The Belkin charges at 100 mA which according to what you stated would still be too high for 10180 cells? It is designed to charge RCR123's. Most RCR123 chargers seem to be around 450mA.
