1.2V Eneloop Low Self Discharge - but they are only 2000mAh
1.2V x 10 = 12V but only 2000mAh

If you used 2 in parallel for each series you could get 4000mAh with Low Self Discharge
1.2v x 10 = 12V but with 4000mAh

This would cost approximately $100 from BatteryBob shipped when you use the discount code "Sheep"

The only other option is to use C cells (D cells as well, but that would be expensive and HEAVY)

C Cell NiMH Batteries come in:
4500mAh = $3.20 x 10 = $32.00 base price
5000mAh = $4.20 x 10 = $42.00 31% more expensive
6000mAh = $6.75 x 10 = $67.50 50% more expensive

If you need any more info feel free to contact me by PM (I don't check this forum often). All the best.

For the D Cell NiMH Batteries in case you are interested:
9,000mAh = $8.50 x 10 = 85.00 - 88% more expensive then the 4,500mAh C-pack (but 200% capacity)
11,000mAh = $9.80 x 10 = 98.00 - 117% more expensive then the 4,500mAh C-pack (but 244% capacity
12,000mAh = $11.50 x 10 = 115.00 - 155% more expensive then the 4,500mAh C-pack (266% more capacity)

For the 24 x Eneloop batteries which are LSD @ $100 310% more expensive then the 4,500mAh C-pack (with 12% lower capacity)

So your best bet for your needs is the 12 x 4500mAh C cells.

By the way - all of these items are from Amondotech.com - so check there for more info about individual battery weights and such. Ever since I started to use Amondotech's Titanium CR123 batteries (tested #1 by CPF'er Silverfox) - as well as the AA Titanium 2100 LSD (low self discharge), I have been hooked on Amondotech. They have excellent prices as well as excellent batteries, chargers, and service. They're not going to carry a 10 cell, 12V NiMH smart charger, you'll have to look on CPFMarketplace for that. Hope this helps.

Edit - I had a complete brain fart evidently before I wrote this post and had to go back and correct like 10 math errors. If there are any other math errors I apologize.

After checking your link though - you're not going to find something cheaper - but who knows what they use in those "battery packs" except the cheapest they can find. At least with 10 x Titanium C-Cells from Amondotech, you know what you are getting - excellent stuff. Please let us know what you choose to do. :)
