This battery replaced the 48AH NMC battery. It is the exact same size just higher capacity! 
 
NMC batteries were built for portable fishing electronics use. They have higher energy density which means  they pack more power in smaller space. These are intended for kayaks, portable shuttles and ice fishing. If used in a boat, please make sure you do not store them in the boat. Remove them after use and bring indoors, charge only indoors and never charge in your boat or leave your charger in the boat where it can get wet. 
 
THIS BATTERY IS FOR FISHING ELECTRONICS ONLY AND WILL NOT WORK WITH TROLLING MOTORS! 
 
Highest capacity battery to fit Garmin Bag in the industry today! Our new 52Ah (769.6Wh) 14.8V NMC Lithium Ion Battery is the highest capacity and longest lasting battery designed specifically for our advanced fishing electronics of today. Running out of power is no longer an issue when running high current electronics of today. 
 
Why 14.8V NMC Lithium Ion? Since most of our fishing electronics today are made to operate up to 17+ volts, this battery has a working voltage of 16.8V when fully charged and 12V  when fully depleted. That means you have the most usable capacity and zero worries of low voltage poor returns/images from your electronics. Unlike the competition selling similar NMC batteries (Usually 11.1V), our batteries use only the best NMC Lithium from Japan. Instead of getting 300-400 charge cycles with NMC from others, Amped Outdoors NMC will give you 800-1000 Charge cycles and a longer life expectancy.
