Description
This Keep Alive® has been specifically designed to be as physically small as possible. This product uses a slightly lower voltage and has a lower capacity compared to our larger Keep Alive products such as the KA1, KA4, etc., and is intended to be used with N-scale decoders, such as the K7D4 and more!
See the "Manufacturer" page for general delivery and pricing information.
