$48 would require some pretty large order quantities and probably low end cells. https://www.18650batterystore.com/collections/featured-products/products/eve-26v-18650 https://www.18650batterystore.com/collections/featured-produ... Currently that is the lowest price I can find for a cell at low quantities, that puts it at $62 to fill the pack which is not too far off. Looks like you would need a 33% discount on those cells to get to $48 which is within the realm of possibility if you purchase in large volumes. To get a decent quality samsung cell you are looking at $118 to fill the pack. https://www.18650batterystore.com/products/samsung-30q https://www.18650batterystore.com/products/samsung-30q
