Most of the Li-Ion batteries on Amazon do not ship to Hawaii individually. I found a bundle flashlight with 8 batteries at a good price (prime) that might ship. Batteries can also be purchased locally at Battery Bills or similar stores.

Let us know if you need anything else. We are looking forward to seeing the outcome of your project. Mahalo!
