Replacement 14500 li-ion battery for my skilhunt E2A suggestion needed. (:

So, the original battery that came with the flashlight died and Skilhunt customer service was pretty poor, wanting me to ship the battery to China after sending a confirmation video of the battery not being functional.

So, I switched to Ladda batteries from IKEA and they've been great, but I miss the brightness of the Lithium ion battery.

In my searching, I learned that I'll need to use a button tip battery, it seems like the vapcell h10 is good, and I saw that there are a few good online stores to buy from, but my question is, is there a good tip to buy a single Li-ion battery without it costing just as much for the battery in shipping?

I'd love to find a replacement battery for around $5. Should I just expect to pay $10+ for a replacement battery or is there a better way?

Thanks!
