Ultralight portable station - batteries

A while back I blogged about methods of reducing the weight of my ultralight portable station:

I believe I have found the ultimate battery for my ultralight portable station. 

There is nothing new about the product below, but I have not had the opportunity to get first-hand experience with these newish devices.

Normally I would use a 7 AH SLAB - Sealed Lead Acid Battery (typical alarm type battery).

The abovementioned SLAB's had served me very well through the years, but there is only one small problem, they weigh 2350 g each. This weight is fairly substantial and would become an issue on long hikes.

I discovered on e-Bay that there are many Lithium-Ion batteries available with different mAH ratings and IMHO they are pretty reasonably priced.

The 6800 mAH LiON battery (same capacity as the SLAB) weighs is at 162 g. This is only 7% of the weight of the 7000 mAH SLAB and it is a fairly compact unit.

Assuming the “blurb” regarding the LiON batteries can be believed then I think this is the way to go. As some insurance I decided to get a 9800 mAH battery complete with charger.

I cannot wait to field test these units……
