Im UK based but I remember reading that ROAR seem to do some pretty hardcore testing (NimH charge ! dead short discharge !) and for exampe the popular Trakpower 3200 saddle is ROAR approved.

Not saying we should be complacent about any aspect of LiPo but nice to know these checks are being done.

8.3.2.4 Overcharge Test
The Overcharge Test simulates a common condition of user error where the pack is being incorrectly charged. The pack is allowed to puff and/or vent, but the pack is not allowed to show open flame at any time during the test procedure. A vast majority of Lipo destructive failures (puffed/vented/burned packs) happen while the pack is on the charger, and a vast majority of them happen because of simple user error in selecting the correct pack voltage to charge at, or charging them with anything other than the correct Lipo battery mode. Forgetting to set the charger to Lipo mode, and then charging the Lipo pack with NiMH mode is an excellent example of what this test simulates.

8.3.2.5 External Short Circuit Test
The External Short Circuit Test basically puts a discharge load on the pack, and then discharges it all the way down to zero volts. The pack is allowed to puff and/or vent, but not allowed to show any open flame for the duration of the test. This test simulates driving a vehicle without using a proper 6v cutoff all the way down to where it won’t drive any longer, or a similar case of leaving a Lipo pack plugged into an ESC for an extended period of time which will also drain it all the way down.
