I think they're lying about that. If you look in the large image of the pack you can see 2.2 Ah printed on the pack... :cry:

Does anyone know what cells they use in these milwaukee XC packs?

This link (http://dewaltownersgroup.com/index.php?topic=204.0) claims Samsung INR18650 13Q Cells or the E-Moli IMR-18650E Cells but I'm not sure what a "refurbished" pack would have in it.

Oh ok, good enough for me. I don't really mind anyways as long as these little packs have some on board cell monitoring/management...or don't need it. I've heard from Doc that the konions in the bosch packs don't really need management, so I think I might go that route. It seems cheaper than many options and more reliable.
@Doc- Do you know what discharge rates the bosch fatpacks can handle? ...or if you could maybe point me in the direction of the fat-pack thread if there is one? I .... questions but I think I decided to go a tool-pack route! :mrgreen:
EDIT: Nevermind, I found the fatpack/konion thread :)

Why would you go this route when you can get a 48V 20ah LiFePo4 for $250~$300 +$166 shipping from HK in less than a week? This also includes the BMS and 5 amp charger!

We do it because many of us have gone the Chinese duct tape 18650 route and found lots of problems with them. Primarily, the problems of reliability and power output. The Sony/Konions are much higher quality, and can put out gobs of power, and use fewer cells which minimizes troubleshooting issues of trying to figure out which of the hundreds of 18650s used in these duct tape packs are bad. Have you ever taken a duct-tape pack apart? It's not for the faint of heart.

I agree, the duct tape battery route sounds sketchy, and I really don't want to have to deal with a return or QA issue from hong kong. You have to pay the return shipping on that sh!t if it goes south...

Plus the ease of a format like gary's multi-dewalt pack setup is very attractive to me. The idea that if a pack goes bad I only have to open up one unit that holds 2ah worth of cells to make any repairs sounds much easier than digging through duct tape.

Ambrose, do the bosch packs have their own LVC/HVC?

The Bosch Fat Packs (BFPs) have some very basic circuitry in them in the battery connector. I've removed the LED circuitry and the temperature sensor circuitry from mine and just wire them directly to my controller through some 3 to 1 Anderson PowerPole connectors.

Here are some pics of the packs opened up.

What about this "deal" on Ebay?
6 used Ryobi 18V lithiums that the seller claims are 80%.
Current bid is $71, but the shipping from China is a whopping $166.
The seller, hobbyway10 has 100% feedback, states that he lot's of them and will "try our best to resolve your issue.".
At the buyer's shipping expense.
He also states, "Our company has a large quantity in stocks, if you are interested in the product,please contact me ASAP!
A large order quantity price will be lower !".
Don't know much about these packs except that they use Emoli cells.
