The Power Shield v0.2.1 specs state a charge current of 500mA via USB, and 1A via DC.
A common guideline for ‘garden-variety’, 1C charge-rate LiPos is to charge them at a maximum rate based off their capacity rating (i.e. a 1C LiPo @ 500mah can be charged at a rate of 500mA safely).
With the Power Shield’s set charge rates (0.5A USB, 1A DC), does that mean LiPos rated below 500mAH/1AH should not be used?
There are high quality LiPos targeted at the RC hobbyist that typically allow 5-6C charge rates. But I’m curious as to the use of affordable, 1C charge-rate LiPos out there that are under 500mAH.
p.s. I also checked the Power Shield’s BQ24030 datasheet, and reckon that the charge rates set during the design of the board are very sensible limits. I just need some clarification towards the safety aspects of using lower-capacity LiPos w/ the Power Shield.
