Tenergy Power Coupon Codes for September 2026 – First Order & Free Shipping

Tenergy Power offers free ground shipping on orders over $50 with the THANKS code for lower 48 states. Drone power packs often start around $75 and can trigger Class 9 hazmat handling fees, so the free shipping threshold removes a common extra charge that hits heavier lithium packs. The code cannot be combined with other promo codes, and delivery can take up to 10 business days using the most economical carrier. This keeps total costs lower when building or replacing drone battery sets without paying standard ground rates.

A 5% first-order discount is available through active Tenergy Power promo codes listed for new purchases. Hobby and toys battery collections start from about $8, so the percentage cut applies directly at checkout on those items when the code is entered. The offer is separate from the free-shipping THANKS code, which does not stack with other promotions. First-time buyers still need to confirm the code remains active before placing the order.

No. The THANKS code for free ground shipping on orders over $50 cannot be stacked with any additional promotional codes. Charger collections currently show discounts up to 40% off, but applying a second code will block the free-shipping benefit. Orders still ship with the most economical method and can take up to 10 business days. Customers choosing the higher percentage off on chargers should expect standard shipping rates instead.

Rechargeable batteries and battery packs, including LiFePO4 deep cycle models, carry a 90-day warranty regardless of promotional pricing. The coverage applies to quality issues based on listed specs such as capacity above 80% within 300 cycles, but excludes misuse, wrong chargers, or improper storage. Promotional purchases do not shorten or void the standard 90-day period. Primary non-rechargeable cells remain excluded from any warranty.

Yes. Tenergy Power accepts purchase orders from businesses, schools, hospitals, and government buyers and offers volume pricing on higher quantities. Custom AT battery packs still carry a 30% restocking fee on returns or cancellations because of the build labor. Coupon codes may apply to standard items in the same order, but the free-shipping THANKS code cannot be combined with other promos. Payment is required before shipping; Net terms are not available.

The 50% off select items code (18650POWER) requires a $100 minimum and applies only to qualifying products. Free ground shipping with THANKS also needs a $50 threshold but cannot be stacked with any other promotional code. RC hobbyists ordering packs or cells that qualify for the 50% offer will pay standard shipping rates. Processing for in-stock items takes 1-2 business days before the carrier picks up the order.

Refunds on orders that used free shipping or any coupon code are subject to retroactive shipping fees. Customers must request an RMA first, pack items in original condition with all accessories, and pay return shipping themselves. A minimum 15% restocking fee can apply if conditions are not met; custom AT packs carry a 30% fee. Solar and off-grid buyers who ordered heavier LiFePO4 units under the THANKS code therefore face those extra costs on any return within the 30-day window.

Batteries collections begin at $1.23 and battery packs and accessories start near $1.29. These lower-priced items can reach the $50 free-shipping threshold with the THANKS code when several are ordered together. Select-item percentage codes may also apply depending on the specific SKUs, but no promotional codes can be combined with THANKS. Non-rechargeable primary cells remain final sale and carry no warranty.

The 90-day warranty on rechargeable batteries and packs remains in effect even when a coupon or free-shipping code is used. Coverage starts from the purchase date and covers defects matching the published specs, but voids for physical damage, modifications, or use with incompatible chargers. Chargers themselves carry a longer one-year warranty. Returns for refund are limited to 30 days and follow the separate return policy rules.
