SysMax/NiteCore i4 V2 Charger - quick easy question

If only charging 2 batteries is it done using slots 1 and 3 OR 2 and 4??

Thanks.

10440's must be paired like this: 1+3, or 2+4

non-10440's: anywhere, e.g. 1+2, 2+3, 1+3, 2+4, 3+4, 1+4

Eneloop AAA's get warm if not paired like 10440's but they can handle 750mA charge rate.

yes

I’m charging little 14500’s for my new SC52, so they are bigger than 10440’s so it doesn’t matter what slots they go in then? Or as they are still small 1,3 or 2,4 would be safer?

Thanks for the replys.

1,3 or 2,4 would be better, that way you’re charging at a rate of 375mA, not 750mA per cell, which may be a little high for 14500s.
There’s plenty of info here if you search.

Also, I’m a bit concerned that HKJ says the current is too high to charge 10440s
in his review of the SysMax/NiteCore Intellicharger i4 V2 here .

I only have a few 10440s so may use my hobby charger for them.

for 14500 it doesnt matter
