Technical Specifications
Who Is This For?
Construction Crews and Demanding Job Sites
Site supervisors, foremen, and trade crews who need a radio that holds up to dust, rain, and daily abuse. The BPR45 carries an IP55 rating and is tested to MIL-STD-810 C through H for shock, vibration, blowing dust and sand, and temperature extremes, with an operating range of −22°F to 140°F.
Warehouse and Distribution Operations
Shift leads, forklift operators, and receiving teams working in loud environments. Up to 3 watts of audio output helps messages cut through equipment noise, and up to 16 hours of battery life is built to last beyond a typical work shift. VOX support allows hands-free transmission when both hands are busy.
Campuses and Large Multi-Department Properties
Facilities, maintenance, and operations teams spread across a large property. With up to 350,000 square feet of indoor coverage and 64 channels organized into 4 zones, each department can have its own channels, and priority scan keeps users tuned to the channel that matters most. For properties that need even more coverage, the BPR45 is repeater capable.
Teams Expanding an Existing Analog Mag One Fleet
Businesses that already run Mag One radios in analog mode and want to add units without changing their system. The BPR45 works with existing Mag One fleets operating in analog mode, and when configured correctly, it can also work with MOTOTRBO radios operating in analog mode.
Key Features
Channels, Charging & Programming
64 channels across 4 zones
Organize your team with up to 64 channels distributed across 4 zones — enough to give each department or work area its own channels on a large property.
USB-C charging and programming
A built-in USB-C port handles both programming and charging, so the radio can be topped off on the go with a standard USB charger. The BPR45 ships with a single-unit charging tray, USB charging cable, and wall adapter.

Can I use a BPR50dx battery in the BPR45?
No. Although both radios use 2,200 mAh Li-Ion batteries, the two batteries are not interchangeable. The BPR45 uses the PMNN4908 battery.
Which chargers work with the BPR45?
The BPR45 ships with a PMLN8599 single-unit charging tray, a PMKN4274 USB charging cable, and a PS000150A31 wall adapter. If you are buying a spare tray, Motorola specifies that the PMLN8599B works with both the BPR45 and BPR50dx, while the older PMLN8599A is compatible with the BPR50dx only. For fleets, the PMLN8893 6-pocket multi-unit charger charges up to six Mag One radios or standalone batteries at once.
Motorola recommends always charging the battery with an approved Motorola charger, as non-Motorola chargers may reduce performance or damage the battery.
Will the BPR45 overcharge if left on the charger?
No. The radio, battery, and charger have built-in charging algorithms and protective circuitry that automatically stop charging once the battery is full.
Does the BPR45 battery ship fully charged?
No. To comply with International Air Transport Association (IATA) policy, Motorola Solutions ships all Li-Ion batteries at less than 30% of their rated capacity. Charge the battery fully before first use.
How should I store BPR45 batteries?
Store batteries in a well-ventilated area at 68°F–86°F with 30%–60% humidity, away from flammable materials. New batteries going into storage should be charged to more than 50% (but less than 100%) within one month of receipt, and stored batteries should be recharged to more than 50% every 12 months. Motorola also recommends removing batteries from radios during storage to minimize drain.
Is the BPR45 waterproof?
The BPR45 is rated IP55 under IEC 60529 for dust and water ingress protection, which covers rain and splashing. IP55 is not a submersion rating, so the radio should not be submerged in water.
