Sup guys!

Simple question: is it OK to fly Spark running old firmware with batteries from Spark with new firmware? DJI Assistant says something about different modules firmware, but drone is able to fly, so is it OK?

Koshen, if your drone's firmware is V 01.00.0700 and you have already upgraded the battery.Then you don't need to upgrade the battery again. The firmware of battery is not updated in the V 01.00.0701 version. Please note that the firmware of 01.00.00.80 is the same as 01.00.00.75. Or you can just follow Thor's advice to upgrade the battery.

Please also update the battery firmware to the latest version to make sure the consistency of all the modules. Thanks.

I gave my batteries, from mine .700 Spark to my friend, he uses Spark on .300, so there is a question - is it OK to use batteries with higher firmware? Or maybe it is even better?

In this case, I would recommend you upgrade the .300 firmware to the latest version. And it can enjoy the new feature and less old problems. Please ensure that both your spark and battery are the latest version for its safety.
