Dji warranty  is really quite pathetic i have a tb 48 battery for inspire 1 pro  charged 17 times and only 9 months old  sent to them in Melbourne  want to charge me  $384.00 thanks for you quality product dji never again

I have just bought 2 tb48 from Australian authorised dealer in Sydney, one that I charged for only a couple of times and within 3 weeks, the battery capacity has fallen to 5200 mah. Is it a case of bad battery? I can't imagine, the battery loses charging holding capacity so quickly.
