Looking to purchase a nice charger to charge 18650 and mainly 26650 cells 2-4 bay
Alotnof chargers can charge 2 26650s at once most of all can. Only 1 I know of can do 4 26650 at once.
I’d second the SV2, whilst not perfect (voltage display missing) it is very good and allows a decent charge rate to 2x 22650. Bar hobby type I’m not sure any others do this, let alone any 4 bay, I’d think that unlikely.
4 bays: SkyRC MC3000 :innocent:
For the cost of skyrc mc3000 you could buy multiple other chargers.
@ Lights-Out,
How about the BT-C 3100 V2 4 slot charger?
2 outer slots can charge 2 x 26650’s at up to 2A each, or 2 x 26650 @1A plus 2 x 18650 in inside 2 slots @ 1A each for 4 x battery charging.
Charges Ni-Mh also.
Cheers,
S-L 
P.S. Like SV2 Rocket too!
It’s between these 2
BT-C 3100 V2
SV2 Rocket
I have opus and xstar chargers. I like the opus can do 2 amp charging, gives voltage readout for each slot. And can do capacity discharge test at 1 amp. You can do a discharge test in one slot and charge in another each slot is completely independent.
Like with the xstar dragon charger you cant run a discharge in one slot and charge in another.
The opus does have a fan some say its noisy doesn’t seem to bother me. I plan on buying another opus to have 2 of them I like it so much when funds allow.
The sv2 charger is more portable it has a car charger that comes with it. I have a power converter so doesn’t matter for me every charger is portable to me. But just depends on your needs. A 2 bay charger isn’t enough for me
The Xtar SV2 does 2 amps on both channels. I use it exclusively for 26650’s.
