Replacement battery for Nolan B4 RCS Kits

This lithium-ion cell replaces the original pack in Nolan B4 RCS wireless headsets. It delivers 3.7V and 900mAh in a 54.20 x 35.65 x 4.65mm form factor. Riders needing a fresh power source for their communication kit can install it directly. The unit carries ISO9001, RoHS and CE certification.

Single-cell voltage and capacity constraints

A 3.7V 900mAh cell provides limited runtime before recharging is required. Users who rely on continuous intercom use during long tours will need access to a charger or a spare pack. The compact dimensions restrict total energy storage compared with larger multi-cell units. No built-in charging circuit is included.

Upgrade from depleted or ageing original packs

This battery restores talk time when the factory-fitted cell no longer holds a useful charge. It is not suited for riders who want extended capacity beyond the original 900mAh specification. Buyers needing longer intervals between charges should consider a higher-capacity alternative if the headset chassis allows.
