I'm not sure how many you need and whether they are standard "C" cells or with solder tabs.

Amazon Basics has a 4-pack for $12.71 at:

For $16.14 per 4-pack, EBL, a brand that I really like has them at: https://www.amazon.com/dp/B00FHVM7GC/ref=sspa_dk_hqp_detail_aax_0

They have solder tab product on Amazon as well.
