[andreym]

Just found here http://epbuddy.com/index.php?main_page=product_info&cPath=1&products_id=45

Coming soon.......Will be available around the end of May.

Junsi's engineers have been developing and testing this new charger for almost one year. It will be launched to the market around the end of May. EP Buddy will be among the first tier of dealers to receive this powerful charger. As what we have provided to our present customers, we will continue offering free balance board, free shipping, and good services to our future 3010B users. Furthermore, every 3010B customer who makes order from EP Buddy will receive a gift pack.
We will also provide 1000W and even more powerful power supplies to make this new charger work at full power.

Specifications:

Who will test it first?
Bit pricey but it should be the most powerfull charger i`ve ever seen!
Why they don`t make 24S charger??? We want 24S !!!

I believe it means that you can discharge 1000W by dumping the current into a battery, typically a lead-acid stack. Using the batteries this way means you don't have to get rid of 1000W of heat as would have to be done with a discharge into a "regular" (resistive or active FET) load.

Thanks for explanation ! - that is really great idea to feed big SLA instead of heat generator ))
But i think not every SLA could take it! (should be like 100AH battery?)

Looks like something similar, in specs at least, to the new FMADirect unit: http://www.fmadirect.com/new_applications/powerlab8.html

I like how these new-type RC chargers have higher input voltages and regenerative discharge features. I'm wondering if these two features could be used together so that in essence, the charger is powered by the pack itself. You could then do a standalone balance on an 8s pack, for instance, and instead of wasting bleed current to heat, it feeds back into the whole pack. Call it "regenerative balancing". This would be great for larger pack capacities, as it would balance very quickly.

Ideally, you'd want a supply equal to the 8s max charge voltage also connected to the pack, so that it could charge and balance at the same time, but I'm not sure something like a MeanWell will take kindly to the reverse current potential.

I'm sure our HC friends must have a Turnigy-equivalent in the works, which could bring the price down a bit. The FMSDirect unit is pretty pricey, at about $280 ($240 until May 10th for "preorders"...).

So basically like these capacitor transfer bms's. It's certainly a better idea than dumping it all as heat

I could see them selling it for less, but the Chargery guy (maker of the iCharger line) and Jason at HK are buddies, and Jason likes the iCharger product line a lot.

Not quite. Those use the switched cap scheme to transfer small amounts of current (100mA...) between adjacent cells. What I'm talking about is discharging the high cells, back into the whole pack. This could be done at fairly high discharge rates.

I doubt these chargers use per/cell switching circuits for balancing. I've toyed with that idea a while ago (as well as with the switched capacitor one), but did not figured out how to make it cost effective.

Slight correction here, Chargery purchases and rebrands a few of the iChargers, as well as chargers from a few other manufacturers. Jun-si is the manufacturer of the iCharger line.

The 3010Bs are slated to be here in ~1 week and will also be available at ProgressiveRC. I've been working and with and testing these units for some time and they are beasts! Charging times for my larger packs has been cut way down.

And yes, they use an individual MOSFET on each of the 10 balancing circuits.

i also noticed that http://endless-sphere.com/forums/viewtopic.php?f=31&t=18994#p276902 )) Nice price to my mind
