Guys, about the suggestion to "married" the cells...
(Frankly i have almost no knowledge of the advantages of this suggestion, but i am sure it is for a good cause, at least to make sure that our
device would got the best amperage deliveries of each "pairs" or in this case "triplets")
But how do you charge this "triplet" and keep their "marital" status okay?
I don't have any I4 or D4 in my possession, but from what i read these chargers can only deliver "uniform" voltage to a "paired-slot" one at a time during charging.
The source:
Test/Review of Charger NiteCore Intellicharger i4 2014 | BudgetLightForum.com
And this is what i understand from that site (please pardon my grammar, and also my lack of battery knowledge if i fail to understand the technical issues)
ie:
If you charge 2 pair of cells at the same time, these charger will deliver certain amount of amperage to one paired-slot (slot 1 and 2 for example) for several seconds and then deliver to another paired-slot (slot 3 and 4 for example) for another several seconds. Thus one paired-slot at a time
Yes, each paired-slot will reach its maximum capacity like in the same time (give or take)
But wait, this is what concern me the most: that amperage delivered to certain paired-slot is divided by two if there are two cells occupy each slot in a paired-slot.
ie:
Cell A B and C are your "triplet", you charge your triplet in a I4 or D4 in this configuration
Slot 1 cell A
Slot 2 cell B
Slot 3 cell C
Slot 4 empty
Slot 1 and 2 are the paired-slot, another paired-slot are 3 and 4.
the charger will deliver 500mah to slot 1 and 2 (paired-slot) for certain seconds, and then deliver 1000mah to slot 3 for certain seconds (since another slot in this paired-slot is not occupied)
In the end you would only get cell A and B "married" while leave the cell C alone
Am i getting this right?
So, i was wondering if charging your triplet powered
device using onboard usb port would be the best.
--edit
(And there might be possibility that the paired-slot in I4 and D4 actually slot 1-3 and 2-4). OK this is mind boggling for me

but that is what i got after re-read the source.
--re-edit
amperage deliveries during charging is simplified, the source numbers are way to complicated for me.
