The battery cell is the heart of outdoor power storage batteries, which determines the performance, safety, and service life of the battery, also the time you can stay outdoors. The outdoor power supply industry is re-shuffling: lithium manganese oxide batteries and lithium titanate batteries with weak storage capacity have been eliminated from the list; flammable and explosive lithium cobalt oxide batteries have gradually been abandoned by the market. The mainstream outdoor solar power storage batteries on the market are now ternary lithium batteries and LiFePO4 lithium iron phosphate batteries.

When choosing the right lithium batteries for your need, it’s essential to learn the advantages and disadvantages of both ternary lithium batteries and LiFePO4 lithium iron phosphate batteries.

In terms of safety, lithium iron phosphate batteries have significant advantages. The ternary lithium battery will self-heat when it exceeds 180°C, and it is easy to catch fire which is hard to fight. The lithium iron phosphate battery will not release heat until 250°C and can withstand high temperatures of 350-500°C.

In terms of service life, lithium iron phosphate batteries still have obvious advantages. Through experimental tests, LiTime lithium iron phosphate (LiFePO4) batteries can be charged and discharged more than 4000 times at 100% DOD. The ternary lithium battery can theoretically be charged and discharged 800 times, but the cycle life will continue to decay in the actual measurement, and it can only be charged and discharged a few hundred times.

But ternary lithium batteries are not completely useless. With the same volume, ternary lithium batteries are lighter and more portable. When the temperature is minus 20°C, the ternary lithium battery can release about 70% of its capacity, while the lithium iron phosphate battery can only release about 54%. Since there are rare users who have a need in the severe cold of minus 20°C, the advantages of low-temperature resistance of ternary lithium batteries do not have many opportunities to show. Not to mention, the LiFePO4 battery has been innovated to add the self-heating function to ensure a normal operation at minus 20°C. Therefore, the market generally believes that lithium iron phosphate (LiFePO4) batteries are the best batteries for outdoor off-grid applications.

At present, many unreliable battery brands are still using obsolete batteries, which not only have fire hazards but also have the risk of explosion. So we recommend you look for well-known brands like LiTime (aka Ampere Time) that are recognized by global markets when purchasing for guaranteed user experience and after-sales service.

Today, big brands of outdoor power supplies are more focused on lightweight products for light-need users. In lightweight products, the portable advantage of ternary lithium batteries is highlighted. So the disadvantages of not having high-temperature resistance and short life can be covered by lightweight usage scenarios.

However, with the improvement of capacity, the requirements for the safety of outdoor power supplies and the quality of batteries will become higher and higher. LiTime, which is known for its large-capacity energy storage batteries, uses lithium iron phosphate cells and has self-developed its intelligent BMS to provide a strong guarantee for its large-capacity outdoor power storage batteries. If lithium iron phosphate batteries are the ceiling of outdoor power batteries, LiTime has already broken through this ceiling. The huge investment in R&D has continuously broken the technical limit. Currently, it can achieve more than 4,000 charge and discharge times at 100% DOD, which is the technical benchmark of the entire industry.

Large capacity means more power and more application scenarios. If your budget is sufficient, it is recommended to buy a big one rather than a small one. Although lithium iron phosphate batteries have many advantages, the cost of raw materials is fair, and LiTime is offering the best budget LiFePO4 batteries with exceptional quality and customer support.

As lithium iron phosphate batteries are more and more recognized by consumers, more and more technology companies have entered this track and launched outdoor power supplies with lithium iron phosphate batteries. LiTime is a professional manufacturer of one-stop energy products and solutions. With 14 years of experience in lithium iron phosphate batteries, the specific performance of the battery has been tested by the market.

So far, in the field of outdoor power supplies, especially in the field of large-capacity outdoor power supplies, LiTime is still the safest choice for consumers.
