Not quite Steve.. Non of the current brands use the circuit protection in the pack itself. They will both happily allow you to discharge them to the destruction point. The voltage protection is available.. but not used by default (I'd never use it).
Fast charging isn't an issue because of the sheer number of flights possible with a given pack (unless you're Jason Somes.. and fly 15 flights a day). The current ECU packs being tested will give you 10 flights without charging. Kent Nogy has been using them for evaluation and has shown that performance including using the ECU pack for the cooldown cycle in the P-120.
The other issues are real but are of little consequence if you pay attention to the details like we all should be with jet models.
