DC charging

[Cumminz]

Looking at picking up another one of these as I'm up to 14 batteries. Question is I can't get it to charge over roughly 4 amps. Would DC charging help this?

The charger cannot deliver more than 100W on a channel (less for the C and D channels). So when charging a 6s pack, it can't do more then 4 Amps. Using DC power input will not help with that.

Maybe a more powerful charger (plus PSU) is what you need.

AC/DC is all meaningless without context. You have to understand the power needed for your battery (see link).
Determine your need ex: 6S =4Vx6x5A = ~120W per channel for a 1 C charge. Webpage has slightly different values. I use 4V instead of 3.7V because its easier to calculate.

Highest AC charger I have seen is 300W (150W per channel), plenty for 6S/5000mAh

So yes, DC will be able to charge at higher values (up to 1000W) but you will need a capable supply. That supply must have sufficient voltage AND current, wattage is somewhat meaningless if any of those 2 are incorrect.

Hope it's not too confusing. If you can give some details we can help pick one out, so will others.
I prefer DUAL channel, QUAD chargers have the tendency to break on one channel or the interface is less than desired. YMMV
Too many options to recommend without more detail.

The charger above is ok and works but I would use it for smaller batteries. I do not consider chargers that can't do 1C on my packs but they will work and only difference is a slightly longer charge time.

Thank you for the informative response. I only have 4 6s batteries. Most are 3s and 4s. I have a venom dual charger but I'm not a huge fan of it. I like the display on this plus showing the current percentage the battery is charged. I will look at that link and consider some other chargers. Haven't had an issue with my other q200, but I've only had it about 6 months
