Are these packs LiPo with some circuitry added inside the pack to protect the cell/s from being exposed to improper charging or discharging?
NO these are not Li-Po's. Please see the first post for the product description. It clearly says LiFe-Po. There is no cell protection circuitry in the pack. That type of thing has proven not to work well. LiFe-Po cells don't need to be used with an LVA or LVC. They charge with any charger that can do A123/LiFe-Po.

Ahhh, I get it now... Li, Fe, and Po... abreviations used in the periodic table of elements. That would make this battery "Lithium Iron Phasphate" then.
I was reading it as "Life" Po... as in long life or something like that. Hahaha!

"Can be recharged unlimited times per day"
1. is this True, as of charged and discharged multiple times perday, in value?
2. what is the storage capacity value on LiFe ? is it 100% fully charged?
3. And how long is this nanophosphate capacity, will be stored ?
3. How much Amps it's Natural Self Discharged?

I'm sorry I don't quite understand your questions. Your sentences are a bit broken and not quite clear. Could you perhaps re phrase them so they are more understandable?
I'd hate to give you the wrong answer because I missunderstood the questions.

I believe what the questions he's asking are:
"can I discharge and recharge as many times as I need in a given day?"
"will it hold the specified mah over the course of the batteries' lifetime and does it come from the factory fully charged?"
"will it hold the same amount of charge after a given amount of storage time?"
"what mah do i expect to lose from self-discharge, if any?"
Just to be on the safe side I will wait for him to reply.
Thanks anyways,

Whoop sorry...that's what i meant, thank's Sabin.
and how much capacity for Lithium Nanophosphate/LiFE for better long time storage ?

1) Yes unlimited charge and discharge in a given day.
2) Way too many variables to determine that. Same as any battery pack...capacity loss over the life of the battery varies depending on average discharge rate, charge rate, balancing, storage conditions etc.
3) too generic of a question........see answer to second question.

Same storage rules that apply to Li-Po's aplly to the LiFe-Po cells. Store them at 60% of the packs rated capacity. So you know the New Hyperion Chargers like the DUO III and the 720i have "Store Mode" for LiFe-Po/A123 cells.

1. If 60% for Store Mode, what if i dont have Store Mode, can any voltages as measurement's for Store Mode, if there is at what voltage should LiFe nanophosphate be stored at ?
2. As LiFe not required to have Voltage Cutoff, is it possible to leave the LiFe nanophosphate at 0V (zero voltage) for safety storage ?
3. Is there any disadvantage if i keep LiFE nanophosphate at 0V (zero voltage) ?
1. If 60% for Store Mode, what if i dont have Store Mode, can any voltages as measurement's for Store Mode, if there is at what voltage should LiFe nanophosphate be stored at ? Li-Po's and LiFe-Po packs must be stored by capacity not voltage.
2. As LiFe not required to have Voltage Cutoff, is it possible to leave the LiFe nanophosphate at 0V (zero voltage) for safety storage ? All LiFe-Po cells have a minimum voltage level of 2.0 volts per cell. No you cannot store them empty. No LVC is needed because once you get to the 2.5 volt range per cell your systems will not function. Example a in RC cars your vehicle will stop rolling when the the pack reaches 5.0 to 4.8 volts for a 2S2P 4500.
3. Is there any disadvantage if i keep LiFE nanophosphate at 0V (zero voltage) ?
Yes you will damage the cell.

without cut off
Will big draw on present Motor system, causes reversible polar effect on LiFE nanophosphate that could damaged the unbalance cells ?
We have been testing these with the Castle Monster systems and they work just fine no issues at all with larger systems just shorter run times. I'm seeing 12 minutes of solid run time in my Caster Fusion EX-1 powered with a CC 2650 system. We've done the testing and if they didn't work we wouldn't be selling them.

1. youre sayin that LiFE can be stored at 2.0v where 2.5v is powerless to the system, what about 2S it's 2.5vx2=5v then , is this still high voltage for an system?
2. what about LiFE 3S result low voltage at 7.5v?
