I recently replaced my OS3 battery with the kit from SharkRF. I am trying to find the best way to maintain the battery and have seen conflicting information from HAMS. I have tended to leave my OS3 on low-charge continuously, but some say you should cycle and let drain down from time to time. One guy has been vocal about his OS2 main board blowing off after taking off the last of the 4 screws to replace the battery? I don't really know the best routine so if someone has data to answer this I would appreciate it.
