Battery differences?

I had a quick question about the differences in the batteries and wasn't sure if anyone had some answers...

I purchased the eGo mower (it comes with the 4 amp battery) and was looking at getting the blower and trimmer (both have the option of coming with the 2 amp battery, but i was only going to get one of them with the battery).

My question is, what is the differences between the batteries, besides the obvious 4 vs 2 amp and $200 vs $100 price?... Will the 2 amp work in the lawn mower with the same power?  Will it just not last as long?  Will the 2 amp charger charge both the 4 amp and 2 amp batteries?... Will the 2 amp battery work in my 4 amp recharger?... They say all the batteries will work in all the machines, but why the 2 different batteries??  What is the difference?

So many questions...

Thanks,
-Thomas

Thomas, like Rob said, all batteries are compatible with all tools and all chargers.  Ego has done a great job here, and one need not worry about tool/battery/charger compatibility.

As far as power goes, when I use a 2Ah battery in my mower I can't tell a difference between it and the 4Ah battery, they both cut the same.  As Rob pointed out, the only difference will be the much shorter (roughly half) run time on the 2Ah battery.

The official run charge time for both chargers are:

CH2100 (standard) charger, 2Ah BA1120 in 40 minutes, 4Ah BA2240 in 80 minutes

CH5500 (rapid) charger, 2Ah BA1120 in 25 minutes, 4Ah BA2240 in 30 minutes

As Oleg pointed out, the added weight will be noticeable in the smaller hand-held tools, though I have used the 4Ah battery in my 15" string trimmer and found the added weight to be quite manageable while trimming my somewhat small yard.  Someone with lots of trimming may prefer to stick with the smaller pack in the trimmer.
