Charger for 6S LiPos

Hi.
I just moved to 6S Lipos and I am looking for a charger to charge 2 packs 6S 5000mAh simultaneously. I can make cabling for parallel charging, is it better to choose high wattage or 2 ports?
Hyperion EOS Duo, Bantam Cellpro 10s or what to choose?
Thanks for helping

I lkie to get as many amps and watts as possible and distribute them the way I want it distributed. Dual pack chargers are not my style.

VOLTS x AMPS = WATTS

6S 5000 mAh at 1C charge rate is 6 x 4.2v x 5 amps = 126 watts
6S 5000 mAh at 2C is 10 amp charge rate and 252 watts

iCharger 206B is 6S, 20 amps, 300 watts
iCharger 208B is 8S, 20 amps, 350 watts

iCharger 3010 and FMA Cell Lab 8 are both 30 amp 1000 watt "capable" chargers. (Output dependent on input of power supply!)

If you wanted dual ports instead of a nice parallel charging and balancing rig ..... you need 6S and 126 watts minimum on each port of a dual port charger.

Depends on your budget, your needs/wants, your power supply and what tickles your fancy

Having used both DUO-style and single-port chargers I prefer single-port. I find it confusing and error prone using a DUO-style. However if DUO-style is your preference and you are on a tight budget you could consider the new iMax B6 DUO which offers 2 x 6S, 200W/10A.

If money is less of an issue then I would go for a high-power single port charger and charge in parallel. Pick of the crop is probably the FMA PowerLab8 once they start shipping, closely followed by iCharger 206B, 208B or 3010B depending on your hunger for power.

If you are not in great hurry it might be worth waiting a couple of weeks to see what the new Hyperion SuperDUO looks like. It is specified as 2 x 7S, 500W/20A which is a big step up from the current generation DUO3 (2 x 6S,180W/15A).

If you know someone that will let you use their DUO-style charger, try it out, particularly if you think you might be charging dissimilar packs or starting/stopping charging packs at different times. See if the usability matches your expectations.

Whatever you choose, don't forget that your budget has to cover a suitable power supply with enough capacity to support charging at the maximum power level you anticipate using. For most chargers over 200W total output that implies voltages in the 15-24V range since they cannot deliver their full rated output from a 12V (or 13.8V) supply.
