I was wondering what the recommendations are for creating a charging circuit for 2 LiPos when they are connected in series, but as a split rail, shown below.
Currently I am just disconnecting them and charging them using the sparkfun charger PRT-10217. Previously I have implemented a charging circuit around the MCP73831 for a single LiPo, so I was wondering if it were possible to use two of those in this type of configuration:
This is of course assuming that I disconnect the batteries from the rest of the circuit first!
Is there anything else I need to be careful of? Thanks
