Sony VTC5 Safe Discharge Voltage?

Oh I read the question wrong sorry. Most People I've seen say 2.5V but I dunno...
I'd rather just charge at 3-3.2 like you said


EDIT: just disregard everything I say today I'm ungodly sick and bloody tired.

 

The Sony batteries above are IMR/hybrid chemistry batteries. These batteries are capable of a much lower minimum discharge voltage before causing physical damage to the battery. The battery is capable of being discharged to 2.5V whereas IMR/ICR batteries have a cutoff around 3.2V.

With that being said, I still believe it is good practice to remove a battery after it has reached around 3.4 volts and recharge it.

 

minimum discharge voltage is always under load.

in most cases voltage won't be recorded in real time while load is applied.

always assume you need head room. resting voltage after load is removed creeps up fast. there'll be no indicators of what the voltage under load was by the time you can hit the button and check the voltage let alone remove the battery and put it on a tester.

personally, i'd prefer a resting voltage of at least 3.5V, but again, that's personal preference at that point.

though, with a 0.76Ω coil, my AW 24 amp batteries show a significant loss of performance and are removed from the mod with a resting voltage between 3.85V and 3.92V consistently. this tells me they're struggling to keep their voltage under load and output the current even at those specs.

the less struggle they have per cycle, the more cycles you'll get out of them as long as they're not abused otherwise.
