In principle, there is no problem, but this is equivalent to connecting four batteries into a 1700mah
4s lipo battery, and then paralleling with the 1700mah 1s battery. In this case, the overall voltage of the battery will less than 3v.
In addition, it is very important that different cells should not be connected to use together. There will be some voltage difference between them. If use together, it will reduce the life of some batteries.
