Lithium Iron Phosphate (LiFePO4) batteries are a type of lithium battery that provide several advantages over traditional lithium-ion batteries based on LiCoO2 chemistry. LiFePO4 batteries provide much higher specific capacity, superior thermal and chemical stability, enhance safety, improve cost performance, enhanced charge and discharge rates, enhanced cycle life and come in a compact, lightweight package. LiFePO4 batteries an offer a cycle life of over 2,000 charge cycles!
Lithium battery safety, reliability, consistency performance is what Teda always insist on!
Lithium batteries are rechargeable batteries in which lithium ions move from the anode to the cathode during discharging and back when charging. They are popular batteries for use in consumer electronics because they provide high energy density, possess no memory effect and have a slow loss of charge when not in use. These batteries come in a wide variety of shapes and sizes. Compared to lead-acid batteries, Lithium batteries are lighter and provide a higher open circuit voltage, which allows for power transfer at lower currents. These batteries have the following characteristics:
Features of Ionic Lithium Deep Cycle Batteries:
• Light weight, up to 80% less than a conventional, comparable energy storage lead-acid battery.
• Lasts 300-400% longer than lead-acid.
• Lower shelf discharge rate (2% vs. 5-8% /month).
• Drop-in replacement for your OEM battery.
• Expected 8-10 years of battery life.
• No explosive gasses during charging, no acid spills.
• Environmentally friendly, no lead or heavy metals.
• Safe to operate!
The term “Lithium-ion” battery is a general term. There are many different chemistries for lithium-ion batteries including LiCoO2 (cylindrical cell), LiPo, and LiFePO4 (cylindrical/prismatic cell). Ionic mostly focuses on designing, manufacturing and marketing LiFePO4 batteries for its starter and deep cycle batteries.
Make sure the load is not exceeding the rated continuous output current. If the electrical load exceeds the limits of the BMS, the BMS will shut down the pack. 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. To reset the pack, attach the charger back to the battery for a few seconds. If you need a battery with additional current output, pls contact us : support@tedabattery.com
Teda Deep Cycle Batteries have true lithium capacity rating at 1C discharge rate meaning a 12Ah deep cycle lithium battery will be able to provide 12A for 1 hour. On the other hand, most lead-acid batteries have a 20hr or 25hr rating printed for its Ah capacity meaning the same 12Ah lead-acid battery discharging in 1 hour would typically only provide 6Ah of useable energy. Going below 50% DOD will damage a lead-acid battery, even if they claim to be a deep discharge battery. Thus a 12Ah lithium battery would perform closer to a 48Ah lead-acid battery rating for higher discharge currents and life performance.
Teda’s Lithium Deep Cycle Batteries have 1/3 the internal resistance of a similar capacity lead-acid battery and they can be safely discharged to 90% DOD. Lead-acid internal resistance rises as they are discharged; the actual capacity which can be used may be as little as 20% of the mfg. rating. Discharging in excess will damage the lead-acid battery. Teda’s lithium batteries hold a higher voltage during discharge.
No. One of the advantages to the Lithium Iron Phosphate (LiFePO4) chemistry is that it generates its own internal heat energy. The outside heat of the battery pack itself will get no warmer than a lead-acid equivalent in normal use.
Every battery of ANY chemistry has the potential to fail, sometimes catastrophically or catch on fire. In addition, lithium metal batteries which are more volatile, that are non-rechargeable, are not to be confused with lithium-ion batteries. However, the lithium-ion chemistry used in Ionic Lithium Deep Cycle Batteries, lithium iron phosphate cells (LiFePO4) is the safest on the market having the highest thermal runaway threshold temperature from all the different lithium type of batteries. Remember, there are many lithium-ion chemistries and variations. Some are more volatile than others, but all have made advances in recent years. Also note, that all lithium batteries undergo rigorous UN testing before they can be shipped worldwide further insuring their safety.
The battery Teda produced are passed UL, CE, CB and UN38.3 certification for safe ship to all over the world.
In most cases, YES but not for engine starting applications. The Lithium Deep Cycle Battery will perform as a direct replacement for your lead-acid battery for 12V systems. Our battery cases match a lot of OEM battery case sizes.
Yes. There are no liquids in the Lithium Deep Cycle batteries. Because the chemistry is a solid, the battery can be mounted in any direction and there are no worries about lead plates cracking from vibration.
Teda deep cycle lithium batteries have built in cold weather protection - Does not take a charge if temperatures are below -4C or 24F in our case. Some variations with part tolerances.
Teda customize heater deep cycle batteries warm up the battery to enable a charger once battery is warmed up.
Lithium deep cycle battery life can be enhanced by not discharging the battery to 1Ah capacity or BMS lower voltage cut-off settings. Discharging down to BMS lower voltage cut-off settings can quickly decrease the life of the battery. Instead, we advise discharging down to 20% capacity remaining then re-charging the battery.

No, it’s safer than lead acid/AGM. Plus, a Teda battery has built in protection circuits. This prevents a short circuit and has under/over voltage protection. Lead/AGM do not, and flooded lead acid contains sulfuric acid that can spill and harm you, the environment and your equipment. Lithium batteries are sealed and have no liquids and give off no gasses.
It’s more about what your priorities are. Our lithium has about twice the useable capacity as a lead acid and AGM batteries. So, if your goal is to get more usable battery time (Amps) then you should upgrade to a battery with the same Amps (or more). I.e. if you replace a 100amp battery with a 100amp Tedabattery, you will get about double the usable amps, with about half the weight. If your goal is to have a smaller battery, much less weight, or less expensive. Then you can replace the 100amp battery with a Teda 50amp battery. You will get about the same usable amps (time), it would cost less, and it’s about ¼ the weight. Refer to the spec sheet for dimensions or call us with further questions or custom needs.
The material composition, or “chemistry,” of a battery is tailored to its intended use. Li-ion batteries are used in many different applications and many different environmental conditions. Some batteries are designed to provide a small amount of energy for a long time, such as operating a cellphone, while others must provide larger amounts of energy for a shorter period, such as in a power tool. Li-ion battery chemistry can also be tailored to maximize the battery’s charging cycles or to allow it to operate in extreme heat or cold. In addition, technological innovation also leads to new chemistries of batteries being used over time. Batteries commonly contain materials such as lithium, cobalt, nickel, manganese, and titanium, as well as graphite and a flammable electrolyte. However, there is always on-going research into developing Li-ion batteries that are less hazardous or that meet the requirements for new applications.
It is best to store Li-ion batteries at room temperature. There is no need to place them in the refrigerator. Avoid long periods of extreme cold or hot temperatures (e.g., dashboard of car in direct sunlight). Long periods of exposure to these temperatures can result in battery damage.
Reusing and recycling Li-ion batteries helps conserve natural resources by reducing the need for virgin materials and reducing the energy and pollution associated with making new products. Li-ion batteries contain some materials such as cobalt and lithium that are considered critical minerals and require energy to mine and manufacture. When a battery is thrown away, we lose those resources outright—they can never be recovered. Recycling the batteries avoids air and water pollution, as well as greenhouse gas emissions. It also prevents batteries from being sent to facilities that are not equipped to safely manage them and where they could become a fire hazard. You can reduce the environmental impact of electronics that are powered by Li-ion batteries at the end of their useful life through the reuse, donation and recycling of the products that contained them.
