For years, the most dominant battery unit for maritime vessels of all kinds was the standard lead-acid battery. However, in recent years, lithium-ion batteries have become increasingly popular with boaters, and are quickly becoming the most popular choice. In contrast to the common lead-acid batteries used in boats for decades, lithium batteries offer a variety of valuable advantages.

How do I charge a lithium battery?

Redway Lithium batteries perform best when charged by a lithium compatible charger. Lead acid or SLA chargers, on-board chargers for AGM batteries, or other non-lithium chargers will charge a Redway Lithium battery but only to 70-80% of capacity. This is because Redway Lithium iron phosphate (LiFePO4) technology charges and is full at a higher voltage then traditional batteries (Redway Lithium charges at 14.4 Volts). Chargers with a lithium battery setting or designed for lithium will charge at the appropriate voltage. Know more

Don’t Overcharge LiFePO4 Marine Batteries

Many boat owners make the mistake of overcharging their lithium batteries. A battery management system usually monitors the charge levels and will automatically turn off once the limit is reached, yet it's essential to ensure that this is working correctly. It's recommended to monitor and remove the battery when it has been charged up to around 80 percent - otherwise, its capability and life may be reduced due to potentially hazardous conditions created by overcharging. Know more

Charge LiFePO4 Marine Batteries in Comfortable Conditions

When charging a lithium battery, make sure the environment is moderate and comfortable. On hot days, bring the charger inside where it's climate-controlled and not in direct sunlight. Likewise, when temperatures drop, find an area that's warm and away from cold or freezing conditions. With our guide to lithium marine battery maintenance now complete, if you have any additional queries about its upkeep or usage - our staff at Redway Battery are on hand to help! Know more

Are LiFePO4 Marine Batteries Safe?

Redway LiFePO4 Marine Batteries provide unparalleled safety and reliability. Containing neither heavy metals nor rare earth elements, including no lead or acid, the Lithium Iron Phosphate chemistry is both nontoxic and noncorrosive. That, combined with zero off-gassing and no need for maintenance or watering, makes Redway Lithium batteries highly sought after. Furthermore, the inbuilt battery management system (BMS) microchip safeguards against over-heating, overcharging and short circuiting while a waterproof casing prevents any accidental contact with the terminals should they get submerged. For exceptional performance and longevity, we recommend using a LiFePO4 charger. Know more

How to get the longest battery life out of my LiFePO4 Marine Batteries?

For the longest possible battery life, you must top off LiFePO4 batteries after each use. Do not discharge or overcharge them by leaving them connected to a charger well beyond the full charge cycle. The battery has a limited number of charge and discharge cycles over the long run, with one cycle either being the complete charge and discharge cycle or a cumulative one. Know more

How should I store my LiFePO4 Marine Batteries?

Redway LiFePO4 Marine Batteries should be stored in a cool, dry place, and fully charged before they are stored. Redway LiFePO4 Marine Batteries can be stored for an extended period of time if they are recharged on a regular basis. For more information, please see our article on storing Redway Lithium batteries. Know more

Keep LiFePO4 Marine Batteries Out of the Heat

Although LiFePO4 Marine Batteries are more heat-resistant than lead-acid batteries, they can still overheat if left in hot and strenuous conditions. Overheating is a major concern with all batteries. Lithium batteries should not be left out in the sun on a hot day—especially when they are charging. When done charging, let the batteries rest and cool down for a few minutes before using them to prevent overheating. Know more

Why does the battery stop working a few seconds after a high current draw?

It is important to make sure that the load does not exceed the BMS's continuous output current limit. If the load exceeds the limits of the BMS, the pack will be shut down. To reset, disconnect the electrical load and troubleshoot your load and make sure that the continuous current is less than the maximum continuous current for the pack. The battery can be reset by attaching the charger back to it for a few seconds. If your battery requires an additional current output, please contact with us. Know more

Are LiFePO4 Marine Batteries waterproof?

If they are splashed with water, they will be fine. They cannot be completely submerged.

Can you shut off or change the BMS board?

No, you cannot turn off the battery or change the BMS board.

Will LiFePO4 Marine Batteries catch fire or blow up? I heard they are unsafe and a fire hazard.

There is the potential for any battery to fail, sometimes catastrophically, or catch on fire. Moreover, lithium metal batteries are more volatile, do not recharge, and should not be confused with lithium-ion batteries. Redway Lithium Batteries use lithium iron phosphate cells (LiFePO4) for their lithium-ion chemistry, which has the highest thermal runaway temperature of all the different lithium battery types on the market. Some lithium-ion chemistries are more volatile than others, but all have made significant advances in recent years. Also note that all lithium batteries are subjected to rigorous UN testing before shipping worldwide. Know more

Will the cost of Lithium batteries become cheaper?

Lithium materials are about 3-4 times more expensive than lead-acid for the same capacity. This will change as worldwide supply increases.

Can Redway LiFePO4 Marine Batteries be fully discharged and then disposed of in the regular garbage?

It is essential to check and follow your applicable regulations before disposing of 12V Lithium batteries. Disposing of waste electronic equipment in standard waste receptacles is prohibited in many countries. Keep only discharged batteries in a battery collection container. To prevent short circuits, cover battery connections with electrical tape or another approved covering. Know more

Where can I recycle my LiFePO4 Marine Batteries?

Consumers can find the nearest participating drop-off location by going online at or or calling 1-877-2-RECYCLE or 1-800-8-BATTERY. Know more

Can I use my LiFePO4 Marine Batteries in cold weather?

Redway LiFePO4 Marine Batteries have built in cold weather protection - the battery cannot be charged if it is below -4C or 24F. There may be minor variations with tolerances on some parts. Know more
After the battery is warmed up, our LiFePO4 Marine Batteries can be charged.
