Lithium (LiFePO4) Batteries

Q – What is the difference between NMC and LiFePO4?
A –NMC Batteries offered by Amped Outdoors are a type of lithium that have a higher specific energy. This means they are 14.8V battery packs made specifically for fishing graphs such as Garmin, Humminbird and Lowrance. They are lighter, smaller, and pack more power with a working voltage range of 16.8V when fully charged down to 11v when discharged. These were intended for portable use and ice fishing. NMC should never be left in a boat or charged outdoors or in a boat. LiFePO4, are a true 12.8V SLA replacement. These are popular deep cycle batteries for storage systems used in Solar, Trolling Motors, Fishing Electronics, and many other SLA replacement applications.

Q – What size battery do I get for my trolling motor?
A – Use this reference: Which battery for Trolling Motor?      Which Battery for Kayak?

Q – Do I need to use a lithium charger? 

A – We HIGHLY encourage the use of the appropriate charger with our batteries. Your SLA charger will put a charge on our battery but are typically only 13.5v vs LiFePO4 chargers being 14.4-14.6v and NMC 14.8V batteries needing a 16.8V charger. To ensure a full charge, speed of charge and proper cell balancing, it is wise to use the correct charger. We sell these with batteries at or below cost to enhance our customer experience. Deltran and many other chargers that are "Lithium", often do not include the feature to reset a battery BMS. This means they will not charge a battery that has been fully drained that may read below 10V.

Q – I cannot get my lithium battery to charge?
A – Most of the time, if a battery will not charge, we want to look at the charger first. Here is a great video on how to diagnose your small form factor battery and charger:

Q – Can I use my boat's on board charger to charge?
A – Possibly. Today most on board chargers have LiFePO4 charring functions. We highly encourage the use of  LiFePO4 rated marine chargers. Ideally, we encourage a 24v or 36v dedicated battery along with our charger. If your charger is not capable of LiFePO4, we would encourage the proper charger that does. 

Q – How to I store my battery when not used?
A – Never store your battery fully discharged. It is best to put a 50% charge on your battery and avoid leaving for a long period of time without charging and in a cool dry place. To ensure the best performance from your batteries for many years, put a charge on your battery at least every 2-3 months. Store your battery in temps of 40-80 degrees and never leave on the charger or charge in below freezing temperatures. 

 

Q – How do I know when my battery is charged?
A – When purchasing a charger from Amped Outdoors, your charge light will be red when charging and will turn green when charged. It is safe to keep the battery on the charger after fully charged as it will not hurt the battery.
