User Guide
Charging: Using the Amped Outdoors charger, connect the battery to the charger (you will see the charger light will turn green)and then plug in the AC cable into the wall outlet. The charging light will turn red when charging and when the charge is complete, the light will turn green again. If you are using our 10A or 20A charger, a fan will also kick in while charging. When the charge is complete, remove the battery from the charger as a float charger is not needed with our batteries. If you are not using an Amped Outdoors charger, please refer to the troubleshooting section if your battery will not take a charge.
Other Chargers: Using an onboard charger, we highly encourage to use one made for 12.8V LiFePO4 batteries only. Most aftermarket chargers will not reset a BMS (battery management system) when triggered. How to reset a BMS is explained in the troubleshooting section later in this guide. We DO NOT recommend the use of a Power Pole or other 36v onboard charging systems on this battery, for proper balancing, each 12v battery needs its charging source when wiring in series.
Connecting your battery: With your source being turned off, connect your battery to your source. Ensure that you have a tight, solid connection and use the provided hardware such as lock washers and washers if you have a battery with bolts. It is highly encouraged to use dielectric grease on all connections to prevent any corrosion from water exposure. Check your connections regularly along with cables, connectors or other components to make sure they are free of corrosion and wear and all connections remain tight.
Housing and mounting: Please ensure your battery is mounted or in the proper box before use. Depending on your application, it is important to keep your battery from moving around or being exposed to elements. Our batteries do not require venting so a sealed case or enclosure will only help protect the battery. Although our batteries have a superior waterproof rating, it is encouraged to keep your products free from elements to prevent the buildup of water, corrosion, and debris. This will ensure your battery will look and perform like new for the expected life of the product.
Long-term battery storage: Never store your battery fully discharged. It is best to put a 50-full charge on your battery and then remove it from the charger. To ensure the best performance from your batteries for many years, put a short charge or use your battery at least once every 2-3 months. The best temperature to store a lithium battery is between 40-80 degrees F. A cool and dry place is ideal. The maximum discharge rate of our batteries would not exceed 3.5% per month in storage. Do not place a lithium battery on a charger for extended periods when not in use. Lithium batteries will last longer if not stored at a 100% charge rate for a long period.
Frequently Asked Questions
Do I need a special charger?
A- We HIGHLY encourage the use of the appropriate charger with our batteries
to ensure a full charge, speed of charge, and proper cell balancing, it is
wise to use our chargers. 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 and may read below 10V.
How to I store my battery?
A- Never store your battery fully discharged. It is best to put a 50% to full
charge on your battery and then remove it from the charger. To ensure the best
performance from your batteries for many years, put a short charge or use your
battery at least once every 2-3 months.
Can I lay my battery on its side?
A- Yes, all of our batteries can be mounted in any orientation as long as you
secure them appropriately. Ensure that all terminal posts are free from all
metal to prevent a short circuit. We do recommend upright as the battery is
intended for stability.
Do I need to discharge my battery before recharging?
A- No, it is advised that your charge your battery before each use. Lithium
batteries will not have a memory and even though it is safe to drain the
battery 100%, it is advised to drain lower depth of discharge. For Additional

Troubleshooting
The battery will not hold or accept a charge
- Lithium Batteries have a built-in BMS (Battery Management system) that will trigger when a battery is depleted or it is triggered into protection. The voltage of the battery may read less than 4v. Our chargers will reset a BMS to begin charging but many on board or aftermarket chargers may not do this because they think the battery is bad. You can connect another charged 12V battery in parallel (red to red and black to black) like jump-starting a vehicle. This will reset the BMS and allow you to charge again.
- If you have our charger, check the voltage output of the charger. The charger will output 14.4-14.6V and will reset the BMS. If it does not, then you likely have a blown fuse on the charger or the charger is not working. Ensure all connections are tight and your AC outlet is working.
Battery just stops:
This is typical of a battery BMS (Battery Management System) being triggered.
One of the following has happened: Depleted Capacity, Short Circuit, Over
Current, Excessive Heat. You can reset the BMS by connecting another battery
in parallel or connecting to the proper charger. The BMS is built in to
protect the battery and your components.

Warnings
Lithium batteries are very safe as long as they are used correctly. Please contact us if you have any questions on your applications.
- Do not crush, puncture, or attempt to dismantle the battery.
- Do not place the battery near an open flame and try to avoid direct heat.
- Do not dispose of the battery in the trash. Please find a local lithium recycler.
- Do not place the battery in fluids such as salt water, acid, or alkaline.
- Do not short-circuit the battery terminals.
- Do only use the approved chargers.
