For OEMs, custom pack builders, and aerospace, government and defense programs.
BUYERS
Tell us what you are building. Here is what each kind of buyer gets from us, and what to send so your first quote is the right one.
Also quoted: distributors and resellers, e-bike and micro-mobility businesses, and solar, RV, marine and off-grid installers, including project-based LiFePO4 orders.
OUR SPECIALTY
A pack is only as good as its weakest cell. In series, the lowest-capacity cell hits cut-off first and limits the whole string; in parallel, cells with different internal resistance share current unevenly. So we quote large orders as projects: one written quote covers the model, the quantity, your batch and date-code requests, matching, documents and shipping.
01
New, first-quality production cells made by Molicel, Samsung, Panasonic, Sony/Murata, EVE and the other makers we list, sold under the maker's own model number. Never B-grade, factory seconds, pulls or recycled cells.
02
We test capacity and internal resistance in-house on every cell, in every batch.
03
Ask for one manufacturer batch and one date code across the whole build. We fill the order from a single batch with matching date codes where stock allows. If we can't, your quote says so before anything ships.
04
Because every cell is measured, we can group the cells for each pack by capacity and internal resistance. Ask for matched sets, and your quote states the tolerance.
05
The B2B team quotes the volume tier, carton and pallet pricing and tax-exempt setup, from under 500 cells to pallet and LTL loads. Net terms and purchase orders are available for qualifying organizations.
06
Hazmat packaging, freight coordination and carrier paperwork are part of the quote. Add insulators, busbars, chargers, cases and empty practice cells to the same order. Ask about models not listed on the site.
Manufacturers change batches without notice, so batch, date-code and matching commitments bind once written on a quote or order confirmation signed by our authorized representative.
A production run, as the manufacturer defines it; definitions vary by maker. Cells from one batch usually sit closer together in capacity and internal resistance than cells from different batches.
A code printed on the wrap or marked on the can. Formats differ by maker, and it is not always the day the cell was made, so read it against the maker's own format.
Single batch required or preferred, any date-code window, matched sets and the tolerance you need, your delivery schedule, and your document list.
BUILDER'S CHECK
One batch narrows the spread between cells; it doesn't remove it. Check every cell's voltage and internal resistance before you weld, and group cells to your own tolerance. Never mix models, ages, capacities, IR values or states of charge in a pack, and build each pack from one batch where you can. Spot weld; never solder. Read the lithium-ion safety warning.

THE PAPERWORK
List the documents you need in your request. We confirm what is available for each model before you order.
| DOCUMENT | WHAT IT COVERS | HOW YOU GET IT |
|---|---|---|
| Manufacturer data sheet | Ratings and the conditions behind them, dimensions, charge and discharge limits | In our data-sheet library where the manufacturer publishes one. |
| Safety Data Sheet (SDS) | Hazards, safe handling, storage, emergency measures, transport information | On request, where the manufacturer provides one. |
| UN38.3 test summary | The UN transport tests for lithium cells, as summarized by the manufacturer | On request, for the model you order. |
| Country of origin | Where the cell was made, for TAA reviews and sourcing screens | On request, by model, as stated by the manufacturer or supply channel. We pass it on; we don't verify it independently. |
| Batch and date-code records | The manufacturer batch and date codes for the cells in your shipment | When available. Ask in your request; your quote states which records ship with the order. |
| Certificate of Conformance | Manufacturer, model, quantity, and batch or date codes for your shipment | Ask in your request. Your quote states whether one ships with the order. |
| Written quote | Price, quantities, and any batch, date-code, matching or document commitment | Every quoted order. Commitments bind once signed by our authorized representative. |
| Tax-exempt or resale record | Your exemption or resale document, on file before the order | We request it separately, not through the form. |
Manufacturers revise data sheets, and the copy in our library may not be the newest revision. Check the revision and date on any sheet you rely on.
PROCUREMENT
Supplier details for your vendor file, and the sourcing rules to check before you buy cells for aerospace, government or defense programs.
SUPPLIER RECORD
From October 1, 2027, Section 154 of the FY24 NDAA bars DoD funds from buying batteries produced by CATL, BYD, Envision Energy, EVE Energy, Gotion High-tech or Hithium, or their successors.
Our catalog includes EVE cells. Under Sec. 154 a battery also counts as produced by a listed company when that company supplies most of its components, so a pack built from EVE cells can be covered. Before you quote LiFePO4 cells or batteries for defense work, ask us for the cell maker by model. If your cells or batteries will end up in a DoD-funded product, say so in your request.
A newer law, 10 U.S.C. 4865, phases in wider limits on battery cells and components from foreign entities of concern, starting in 2028. Check the clauses in your contract.
Trade Agreements Act status depends on country of origin. Ask for it by model.
PLEASE NOTE
Procurement information, not legal advice or a compliance certification. Final acceptability depends on the product, the batch, your contract and its flow-down clauses, and your own compliance review.

New, first-quality production cells made by the original manufacturer, such as Molicel, Samsung, Panasonic, Sony/Murata or EVE, and sold under that maker's own model number. Never B-grade, factory seconds, pulls or recycled cells. Reseller-brand and private-label cells are outside this description; ask us for the original maker.
Ask in your request. We fill the order from a single manufacturer batch with matching date codes where stock allows; if we can't, your quote says so before anything ships. Manufacturers change batches without notice, so a batch or date-code commitment counts only when it is written on a quote or order confirmation signed by our authorized representative.
Yes. We test capacity and internal resistance in-house on every cell, in every batch. Ask for matched sets, and your quote states the tolerance. Still check each cell before assembly, never mix models or ages, and keep each pack to one batch where you can.
List what your receiving inspection needs (Certificate of Conformance, batch and date codes, country of origin) in your request. Your quote states which records come with the order.
Yes, for qualifying organizations, after we review the PO terms and any flow-down clauses; exceptions are noted on the quote. For a tax-exempt purchase, send your exemption document before you check out so tax isn't charged. Tax charged before your exemption is approved may not be refunded.
It depends on the maker, the product and your contract. From October 1, 2027, FY24 NDAA Sec. 154 bars DoD funds from buying batteries produced by six named companies, including EVE Energy, whose cells we stock. A battery built mostly from those companies' cells can count as produced by them. Ask for the manufacturer and country of origin by model, and tell us if the cells will end up in a DoD-funded product. This is procurement information, not legal advice.
Wholesale pricing runs from under 500 cells to pallet and LTL orders. Smaller quantities can be bought online.
It depends on the maker and model. Your quote gives carton and pallet quantities for your model.
Wholesale, pallet, LTL, freight and custom-quoted orders are final sale unless a written agreement signed by an authorized representative says otherwise. Report transit damage or a dead-on-arrival cell within 5 days of delivery, with photos, and wait for RMA instructions before returning anything. Verified DOA cells are replaced after testing.
Compare the cells with the maker's data sheet and our guide to spotting fake 18650 cells: can codes, weight, voltage and resistance. If anything looks wrong, text a photo to 1-833-419-2192.
