some quotes about DJI Batteries regarding battery fires
But there’s one more solution, and DJI, creator of the popular DJI Phantom series of quadcopters, holds the patent to it.
Shortly after the launch of the original Phantom, developers with DJI wanted to ensure that consumers with less experience with soft pack batteries would be able to use them.
“We knew it would be a game changer because it further lowered the barrier for first time pilots interested in quads,” said DJI spokesperson Michael Perry.
Development on the Smart Battery for the Phantom II
line of drones began in April 2013.
The Smart Battery’s are also LiPo batteries, with a capacity of 5200 mAh and voltage of 11.1 V. Power management is handled internally, meaning no balance connector is required to charge.
The one major criticism Phantom II users have? The price.
DJI smart batteries cost about $130, in comparison to the $20 LiPo batteries sold on DJI’s site (and often found cheaper on hobby sites).
“We cannot say for now if the price will drop. Part of the reason that the batteries are priced higher than normal LiPos is that all the smart features requires additional hardware (not just the LEDs, but circuitry), software and testing costs,” Perry said. “We feel that the intelligent features that people get out of these batteries corresponds fairly to the price differential with typical batteries.”
And that’s not to say that the DJI Smart Batteries are 100% foolproof.
“Heat is a big enemy of all Lithium battery chemistries, so even a DJI smart pack could be damaged by letting it sit inside a closed vehicle on a hot sunny day for instance,” Salt said. “Chances are it would never start on fire, but there is still some risk there – especially if it’s fully charged.”
