No doubt Cappy. A 40 amp 1000 what charger isn't needed by everyone here. If the OP let's us know what size 6S packs he uses, it'll be much easier to suggest a proper charger instead the friendly macho "mines bigger than yours" banter we've been having.

My main usage is for nothing over 2800 ma 3 cells, but I do want the capability for charging 2 5000ma 6s at once. Who knows I might start flying my 700 heli again someday. I think Im going to order the thunderpower. Others have some extra features that I would like but for 99 bucks I can get what I want in a brand that isnt too cheap and TP confirmed it will work on all chemistrys Only thing Im really giving up is the second display

how many digits below the decimal does TP chargers do? The HV thing is a software patch, I just got an update email with my Graupner that download is ready for High Voltage batteries,

At IRCHA I had seen the factory Graupner pilots setting their lipos to a charge voltage of 4.21VDC instead of 4.20, I started doing this and even in my small packs I see them all come up to 4.20 across more cells more often than not.@ 4.20 I would rarely see 4.20 on cells.

Even though my graupner is a 7s 800w total two port charger, it is not that on 12VDC, its only a 300W by default when using 12VDC settings as shipped. Again I did not realize this until the factory pilots who had a 24vdc power supply, where then resetting the input voltage menu that would now allow the 800w.

So then this got me thinking 24VDC so I bought some 12vdc power supplies, isolated the DC side ground plane from case and then went and added an external DC ground to case that is easily removed if using multiples that are series together.

Then it got me to thinking the 110VAC plug in receptacle is really only good for 1500W then you would need a second alternate breaker supply circuit ,which is really not that practical within close proximity to secure, SO I guess 1500W is max if using 110VAC plug in receptacle.......

I was intrigued with those DC charger generators that someone posted in conjunction with a battery, got me thinking :? hmmmm.

Household 15A breaker outlets are good for 1700 plus or minus and commercial buildings and some household outlets are 20A or good for 2200-2400W. on 110-115V. Most everywhere else in the world that has 220V outlets and can go 3000W plus.
I've always wondered why we are the only place where it's 110-115V AC.

Psht... :dk: Well, isn't it makes sales of vacuum cleaners in department stores easier when power presented in Amps... That way no one have to bother with watts(and kilowatts) :nerd:

On a bright side chargers with US plug seems to be cheaper. :tu:

Just wanted to say I got the thunder power charger in and a 20 dollar 300 watt p/s in yesterday and got it put together and charged a couple batts and it works great. Happy for 99 bucks. The only downside is making sure your on the right port cause you've only got one display

That's the way my Hyperion DUO charger is. You have to make sure you are looking at the right port. Most the time I just end up using my VH X-Charger. So nice to use - I have 3 of them now.
