What would happen if you connected 2 LiPo chargers (in parallel) to a LiPo batte

Anyone?  Would it charge twice as fast?

[Richard Crowley]

NO. At best, it might charge slightly faster, but more likely at the "normal" speed.
At worst, overcharging the batteries can cause " overcharge, over-discharge, over-temperature, short circuit, crush and nail penetration may all result in a catastrophic failure, including the pouch rupturing, the electrolyte leaking, and fire."  --  FAA Battery Incident Chart, includes incidents of Lithium-Polymer-Air ignition after puncturing.

Yes.  The initial constant-current phase will go twice as fast.  The CV phase will take as long; during that time, one charger may register as "done" while the other continues.

It's not recommended, for the reasons listed above.

Watch Daves video about lipo charging profile.. Watch it right now... There is very good reasons why charge is current limited...
