thanks rscamp, that one seems pretty good for my purpose, but that means, i'll probably have to build my own "pods" of lifepo4 batteries to charge at least 2 pack of them together at the same time
(originally i was planning to order those PING's lifepo4 packs from ebay, and save myself the trouble to build and solder those on my own, and find a compatible BMC for the packs, etc)
i saw the youtube video of that charger, it was very informative, however i still have a question, you mentioned it can do 550w x2 with 2 separate circuits
now by that you mean the circuit from the wall-plug?
or you are referring to 2 separate power supply so each one will deliver 550w?
The project "bike" i'm setting up is more a Trike than a Bike, so finding space for the whole setup shouldn't be too hard, rather the weight is the only thing i'm concerned about.

so i was reading this topic over at http://endless-sphere.com/forums/vie...p?f=14&t=28934
and seems like this PSU might be a good option http://www.ebay.com/itm/MW-24V-DC-25...item58929e89c4
or i could probably modify a couple of computer server PSU to do the trick, which are more affordable and easily accessible to me
i'll probably use 2x 800w PSU or something along the lines, maybe even 2x 1100w if it can make it charge faster
hmm... that's an interesting topic, so it seems like iCharger 3010B 1000W (http://www.hobbyking.com/hobbyking/s...e_Charger.html
) is even better, and the Hyperion 1420i could develop bugs after a while
uhhh... after some more reading found this hot PSU Turnigy 1080W 220~240V Power Supply (13.8V~18V - 60amp) http://www.hobbyking.com/hobbyking/s...dProduct=20612
i wonder if that is enough to power the iCharger 3010B 1000W
either way that's what i find the most complicated thing about using lifepo4 batteries, yet they are the only ones that can recharge fast safely and can be recharged often before having to replace them again, and having to calculate how to pack your batteries to match the charger charging capabilities.... this notion is definitely new to me
i never had to bother with that before, and now i cracking my head open just to figure out the best setup, for a quick charge, yet still able to come up with 48v for a 500w motor to last me a decent ride before having to make a pit stop for a quick charge again.
that's the nice benefit of lifepo4, all the previous non lifepo4 batteries and charges takes average 4 hr to charge, and that is simply waaaaaaaaay too long if you are stranded outside, and did not bring a spare battery with you.
that's the whole thing i'm trying to avoid now with the new setup, a fixed regular pack to power the normal stuff, and then the lifepo4 "backup" battery pack
in an analogy the lifepo4 backup battery pack will be like the gallon of gas tank that you will always carry with you for long trips in the wildness far from any gas station
and as such i wan to be able to refill it quickly the first power outlet i come across with so it wont run out before reaching home or wherever i wanted to go
- - - EDIT 2 - - -
just finished watching a video of the iCharger 3010B 1000W in action http://www.youtube.com/watch?v=ZwS95pEALHg
and i think i'm in love
that's pretty close to what i want to setup, now i just need to figure how to pack the lifepo4 batteries to make good use of the 10 cell monitor
in other words now i need to find larger lifepo4 batteries that can hold more power and attach them in series, as having several small packs of 10 will defeat the purpose of fast charging
