DUSLAN Sub C NiMH 4200 mAh standard battery 6-pack with tabs

Sub C NiMH 4200 mAh Pack

This six-pack supplies 4200 mAh Sub C nickel-metal-hydride cells with tabs on both ends for soldered assemblies. Each cell delivers 1.2 V and measures 43 mm by 23 mm. The chemistry avoids memory effect so partial recharges do not reduce usable capacity. Hobbyists and technicians building custom packs for RC, lighting or portable equipment will find the format convenient.

Sustained Discharge Behaviour

Rated for up to 1000 recharge cycles, the cells maintain reliable service life under repeated deep-drain use. NiMH chemistry provides steady voltage through the majority of the discharge curve rather than a sharp drop-off. Tabs on both ends keep internal resistance low in series strings, helping the pack deliver consistent current during extended runs. The absence of memory effect means the full 4200 mAh remains available after many partial cycles.

NiMH Chemistry Practical Limits

Nominal voltage sits at 1.2 V per cell, so series strings produce lower pack voltages than lithium alternatives of the same count. Self-discharge is higher than low-self-discharge NiMH variants, requiring a top-up charge after weeks of storage. Charging must follow NiMH termination methods such as negative delta-V or temperature cut-off to avoid overcharge damage. The 43 mm length and 23 mm diameter fix the physical envelope for any holder or shrink-wrapped bundle.
