Description
The IBP-1 is a replacement and spare battery pack designed specifically for the RICO Mk1 thermal weapon sight. If you run a RICO Mk1 in the field or on a dedicated patrol rifle, carrying a second battery is the simplest way to eliminate the one failure point that has nothing to do with the optic itself — a depleted cell at the wrong moment.
The pack uses a cam locking mechanism to seat and release cleanly under pressure, without the fumbling that comes with friction-fit or screw-retained designs. That matters when you are swapping power in low light or with gloves on: the lock engages positively and releases deliberately, so there is no ambiguity about whether the battery is seated correctly before you move.
The lithium ion chemistry holds a charge through extended storage better than older nickel-based formats, which is relevant if this battery lives in a kit bag between uses rather than cycling daily. iRay USA rates the pack at 4400 mAh, giving the RICO Mk1 the same runtime ceiling as the factory-installed cell rather than a reduced-capacity compromise.
This is a first-party accessory from iRay USA, built to the same specification as the battery shipped with the sight. If you are running a RICO Mk1 in any role where continuous operation matters, a spare IBP-1 is a straightforward logistics decision rather than an optional upgrade.
