I have an Inspire 1 with 2 TB48s and 3 TB47s. Over this past winter, I put my inspire in storage here in OH. When I took it out to fly, 2 of the TB47's wouldn't charge at all and the red and one green light would flicker. Since the batteries were over 7 months, DJI said to replace them, meaning spend$100+ per battery on new ones.
One of the techs suggested that if I wanted to "carefully" tinker, I could take the facia (white cover on top of the battery that snaps on each end) off and disconnect the lead to the proprietary DJI circuit board to see if that would "fool" the circuit board into a recharge mode. Did not work.
However, I went a step further and unscrewed the four phillips screws that hold the circuit board to the facia and disconnected the lead to the circuit board as well as the other end that goes to the top of the battery.
I then plugged the battery into the DJI charger an after 5 minutes the batteries started to warm up. After about 10 minutes, I unplugged the batteries, reconnected the lead to both the circuit board and the battery and plugged it into the charger and voila, both batteries proceeded to do a full charge cycle.
After charging I put each battery on the Inspire, powered it up and installed the new battery firmware update release last week - April 8, 2016 or so - to correct a DJI identified problem that prevented some batteries to come out of hibernation mode.
This is obviously a DJI battery problem (probably in the chip's charging algorithm) and rather than doing the right thing and giving Inspire customers either replacement batteries or a patch, they decided to tell customers to BUY new batteries while they knew full well that it was a problem in their software and not in the customer's batteries.
Another example of DJI's customer disservice.
Hope this is useful to others |
