Accessories
21700 cylindrical lithium cell supply for OEM buyers who need higher cell capacity, fewer parallel groups, energy / power / high-rate class shortlists, IR matching, and batch traceability within the available equipment space.
Mature 18650 cylindrical-cell battery packs for OEM devices that need stable sourcing, flexible series-parallel design, BMS protection, harness and connector customization, and cost-controlled sampling.
32700 LiFePO4 cylindrical cell supply for safer long-life OEM modules and packs that need 3.2V building blocks, matching, cycle-life planning, and batch traceability—not maximum Li-ion energy density.
Product FAQ
18650 is often better when the device has smaller diameter constraints, mature existing pack layouts, cost-controlled sampling, or supply-chain requirements that favor established compact cell formats.
No. This page covers cell supply, class shortlists, matching, and traceability. Pack architecture, BMS, enclosure, and connector design belong on Custom OEM or the custom 18650 pack page.
Choose energy class for runtime-first compact packs, power class when continuous current and capacity must balance, and high-rate class when pulse or tool current dominates. Continuous versus pulse rating and thermal rise should be confirmed before sampling.
