I was wondering if it would be possible to change out the chip on the USB/DC Lithium Polymer
Battery Charger, item 280, to the 8.4v chip instead of the 4.2v chip. I
need the charger to charge a 2 cell LiPo battery. Would this be possible? Is there more to it than just switching the chip? I can tell that the board was designed to be compatible with the 8.4v chip because of the check box on the right side of the board. We
need this for a solar powered UAV for our senior design project. Please let
me know ASAP. Our whole design is riding on this charger.
Also, to be clear, will the charger cut off when the battery is completely
charged so it doesn't overcharge? And what is the maximum input amperage for
the charger? I know the max output is 1.2A, but is there a maximum input
current? And if I am using the second JST port to discharge the battery at
the same time, is there a limit to the output of the battery? One more
question, how do I make it so the charge rate is 1.2A instead of the
Again, I need to know ASAP due to deadlines for this project.
Any other advice you have is appreciated.
