Sorry, but we have now depleted our stock of the lower boards for this kit. If you need just the upper board please call us to order.
These are the replacement battery boards for the Humminbird Portable Base PTC-P. When the batteries leak, the acid corrodes the battery boards and results in a no power scenario. It's a good idea to keep a set of these on hand as when they're gone you'll be out of luck! Kit includes: 405484-2 Lower Battery Board 405483-2 Upper Battery Board **Portable case not included and is only shown for reference**
PN# 405484-2 & 405483-2
