Charging an LiPo with another LiPo
I use a 10000mAh LiPo (emergency phone recharge type) to run my mini wifi router in the field for connecting SkySafari to my SXP. I have 2 of these batteries. Is it electronically ok to have these connected in series so essentially one LiPo charges the other, all whilst running the router, more or less getting 20000mAh?
Or is there potential for issues here?
Not that the router uses much, but just like to know if say one gets down to 10%, plugging another LiPo “on the fly” in to recharge it but not disconnecting the router from power would be ok?
