I had 4 new NiteCore 2300 protected cells in a Niwalker Minimax Nova MM15 Version 2 totally discharge while it was supposedly locked out. My question is aren't the protected cells supposed to shut down before that happens?
All 4 cells were reading 0.0 vdc. I charged them and they took a charge to 4.19 vdc. Are you saying the protection did kick in and when it does they read 0.0 vdc? I didn't do any manual reset of any kind. I used a Nitecore Intellicharger i4. Since I didn't do a reset on the batteries is there a way to tell if they totally discharged or the protection kicked in?
I believe the batteries are set up in series in the Niwalker Minimax. The batteries drained were not in use but in standby-lockout mode on this light. The endcap does not lockout on this light and it has a very high standby drain on cells. I enacted a switch lockout which was supposed to alleviate that or lessen that at least.
I did not do a manual reset on the cells, is that normally necessary? I am also curious if they were actually at 0 vdc how the charger knew they were lithium batteries. It is a multi chemistry charger.
For what it's worth Selfbuilt's review stated the cells are in series. From the review "As before, the four 18650 cells are in series, not parallel." http://www.candlepowerforums.com/vb/showthread.php?385451-Niwalker-MiniMax-Nova-MM15-(2xMT-G2-4x18650)-SHIPPING-Review-RUNTIME-BEAMSHOTS/page3.
I used a Nitecore Intellicharger i4.
As always thanks for any input it is much appreciated.
Yeah, I see that, but I think he's wrong on the 'series' part, having looked at a German review on the light with pictures of the battery carrier stuffed.

Anyhow, 4*3.7v cells, in series probably isn't going to give you 2+ hours at 5,000+ lumens and that would be 16.8v hot off the charger.
Good luck and as others have stated, just keep the cells out of the light until you decide to fire her up.

I'm no expert but I believe the cells have to either be in series or possibly series/parallel. If I recall correctly an MTG2 led needs a min of 6vdc or thereabout.
