The MCP73831 datasheet says it can charge Li-Ion and LiPo batteries and the MAX17048 is for both battery chemistries…
Is there anything dangerous or technically wrong with using a Li-Ion 3.7v Battery on this board ? I already have Li-Ion batteries but hesitate to use them (the whole swelling and blowing up thing)… and I will flat out admit I currently know almost nothing about these batteries with the exception of using them in store bought products.
