Price Discrepancy in Batteries

[broloch]

I was looking at batteries and was going to build a pack, and I was going to use 12V packs. I was looking at the pricing and found this:
Does anyone know what the price discrepancy between these two is?
Do you think it is a glitch in the website, or is there a big difference in the two batteries that I cannot see.
Both discharge at a maximum of 40A., and there is a $16 price difference... wtf?

$43, 12V, 4200mAh

$27, 12V, 4200mAh

I think the difference is part of the description, "•Specially designed for Airsoft guns..."
Electrically, they look identical.

Yes, the specialization would make them target a crowd that's willing to pay more.

Also, the standard battery is .15 lbs lighter(might just be housing, I guess. The airsoft could also have a built in LVC module or some kind of battery protection but don't know about that) and the airsoft one states "Specially designed for Airsoft guns for power intensity and long running time." suggesting that these have a lower internal resistance but the identical maximum discharge rate suggests otherwise.

i'd suggest staying away from those and look at www.ebikes.ca for the nicad packs, F cell size is good for 8000mah ( or 8ah ), nicad is slightly bulkier than nimh but they don't self discharge as fast, and are a bit more abuse tolerant. ( My original nicad packs going on 4th year are still going strong ! )
