I haven't read all the posts, so I'm sorry if this is redundant. Keep in mind that whatever charger you're using also needs to monitor all 6 of the cells and keep them all within a couple hundredths of a volt. Yes, in a pinch you can fast charge without balancing the cells. But when the job is over, balance the cells when you get home.
A slow charge is better (less than 1C). Charging at 2A (about .3 or .4C) will make your batteries last a lot longer. Keep them at about 3.7v/cell (storage voltage) if you're not planning on using them in the next 4-10 days. It doesn't take very long to charge from 3.7v/cell to 4.2v/cell. If you don'y need max duration from each battery pack, fly them at 4.0 -4.1v/cell.
Tips for long battery life: LiPo's like to be stored at 3.7v/cell. They don't like to be stored at full charge (4.2v/cell). They don't like to be discharged below 3.3v/cell. Below 3.0v/cell is asking for trouble (like buying a new battery). While they can be fast charged (depending on their C rating) they like a slow charge (less heat). Keep the cells balanced. You're better off flying 2 batteries for 10 minutes each, than flying one battery for 20 min. LiPo's like to be around 3.7v/cell. Label your batteries and run discharge cycles on them every so often and record their capacities in a notebook. At some point in time, it'll drop off and the battery gets retired (just use it as a power source for charging your Tx, but don't fly it). Batteries continue to be the most frequent source of failure in R/C aircraft.
Of course, all this requires a dedicated programable charger, and the appropriate connectors.

It's actually completely wrong, sorry but reading the context and knowing what you're taling about is kinda important.
The Inspire battery has an integrated balancer and doesn't even have a way to connect an external one. And the cells are a different chemistry that is charged at 4.35V. Discharge voltage is mostly irrelevant as the battery reports remaining charge in % of capacity. Etc.
The Inspire uses a battery with internal electronics and quite a few differences from usual lipos, so the "common" good practices don't really apply.

You are incorrect on this. The battery will ask what it can handle from the charger. Its a smart battery with a processor on board. A higher amp output won't hurt the battery. The battery will charge as fast as it can with the available amperage.

Hi Guys, This is Stacy from AerialDroneAccessories.com I appreciate you guys taking a look at our multi charger. The difference4 between our system and the strip offered by the guys in China is vast. We did a lot of work to create a product that will safely charge your Inspire 1 Batteries. It's circuit protected and is good for your batteries to charge this way and not over powering a small power supply that wasn't made to charge that many batteries. If you have questions about it please feel free to give Robert a call at (205) 965-6571. He will give you all the information you need to make an informed decision.
Hello I'm the developer of the inspire multi charger on ebay you guys are talking about. I would like to clear up some things then you can make your own decisions. First the power supply is 600 watts set to the correct voltage to charge the indpire batteries. This charger will charge the inspire batteries faster then stock charger. The power supply is mean well one of the top on the market and I 3d print the box on top then custom wire, build, adj. To specs and test every unit be for shipping. The power supply itself has circuit breaker protection, over heat protection, over voltage protection and a cooling fan. The inspire battery has these features as well so no chance this charger can harm the batteries. I have sold alot of these chargers and have had no complaints so far. If you have any other questions please contact me at robertsedlak.skyviewaerial.com I'll be more then happy to explain anything else. Oh also please be carful if you buy those charging strips on ebay you hook your stock charger too its going to overheat the charger if you do 3 batteries at once I've contacted the guy and asked him to be carful selling those. Thanks for your time.

How are you preventing one battery from discharging itself into the others if it's at a higher charge state or vice versa?
(Note: can't see ebay listing nor description, "this listing is not viewable in my country").
The inspire battery controls input and output and over voltage and discharge hence smart battery.

No it does not "control" it, simply monitors and provides a safety cutoff. Connect a full battery and an empty one, you'll see the current shoot way above the rated maximum charging current of the empty one, and the built-in safety turn it off if the voltage difference was high enough.
Based on everything I've read, I've been left with the impression that charging these batteries faster than designed can/will cause damage. Is this correct or not?
Has anyone here been keeping up with this thread at DJI?

Faster than designed is bad, but "designed" is 180W charging power or close to 2C.
I stand corrected we have current limiting resistors on each port so have not seen that happen before but that does make sense. Thx.
I'm extremely new to the quadcopter world and it's environment for that matter.I'm in need of a multi-battery charger now and I've come across a few companies.I keep hearing about the smart power charger and now the DJI Hex Charger.The DJI is a lot cheaper, but it's just come out and the buzz on it isn't very loud.Which one should I Invest in, the Hex Charger or the SPC4500..?
any info would be great..thx
