Power Bank Maxi

Ensure smooth, uninterrupted running on your OO Scale layout with the HM7000 R7416 Power Bank Maxi, the largest power storage unit in the HM7000 range. Designed to support locomotives with higher current draw and larger motors, this advanced stay-alive module keeps your model trains running through dirty track sections, complex pointwork, and short power interruptions.

Ideal for sound-fitted and heavy-duty locomotives, the Power Bank Maxi enhances reliability and prevents unwanted stops or decoder resets, delivering a more realistic and enjoyable operating experience across your layout.

Features

• Largest HM7000 power bank designed for high-demand locomotives
• Compatible with HM7000 Bluetooth® & DCC decoder range
• Plug & play socket connection – no soldering required
• Compact installation size: 22 x 12 x 10mm
• Maintains power through dead spots, points, and crossings
• Prevents sound decoder resets caused by brief power loss
• Optimised for locomotives requiring higher current draw

The R7416 Power Bank Maxi works in conjunction with HM7000 decoders to provide short-term energy storage, ensuring continuous operation even when electrical pickup is momentarily interrupted. This is particularly beneficial on layouts where track cleanliness or complex track geometry can affect consistent electrical contact.

By smoothing out these interruptions, the Power Bank helps maintain both motor control and sound functionality, creating a far more realistic and stable running experience. It is especially suited to larger locomotives or consists that demand greater power delivery.

For smaller locomotives, a more compact alternative is available in the form of the R7377 Power Bank, offering similar benefits in a reduced footprint. The R7416 remains the preferred choice where maximum energy storage and reliability are required.
