A budget pack that doesn't cheat on chemistry. SMC's HCL-EC series — High Cycle Life Economy — is built on 100% LCO cells, where similarly-priced packs typically blend in cheaper chemistries that quietly cost performance and lifespan. The result is a 3S 11.1V pack with a genuine 5200mAh capacity (true-rated, ±5%) and a 100C rating, cell-matched at the factory, in an impact-resistant hardcase with 12AWG wires and a Deans-style T-plug fitted. Everyday bashing, club racing, long practice days: this is the honest workhorse.

The Fit Check

Two questions before checkout: does your vehicle run a Deans/T-plug connector (if your ESC wears a different plug, you can use an adapter), and does the battery bay take a 38 × 47 × 139mm hardcase? Standard 1/10-size trays generally do — but thirty seconds with a ruler beats a return. Weight: 381g.

Charging and Care

Balance-charge every time on a LiPo-capable charger — 1C (5.2A) is the longevity sweet spot, and while the pack supports up to 5C fast charging, SMC's own note applies: higher rates trade away capacity and cycle life. Charge in a LiPo-safe bag on a non-flammable surface, never unattended, and store at storage voltage between run days. The hardcase shrugs off knocks, but a damaged or swollen pack retires immediately.
