A lot of helpful guys should chime in right about now . B

Thanks for the input. I will definitely be including a fuse on the new battery as well.

These are the specs for the HDS-5
Power Supply: Input Current 0.7A at 13VDC with backlight on, 0.4A with backlight off
Its not the 12volts that's your issue, its the amps, you don't have enough amps in that battery. I would suggest that at a minimum you get a 12v 12amp battery and if you have the money get a Bioenno LiFePo4 battery, they're expensive but they run and run and run.

Its a battery I used for a smaller FF. It was plenty fine for a day out on the water but then again it didn't draw as much juice as the new one.
I looked up the Bionenno but didn't see a 12 amp battery. I see a 10 amp or 20 amp option. The price difference is substantial at $84 vs $222. Could I get away with a 10 amp?

I have heard that this also damages the battery so that it won't hold a charge as long too.
