A Partial State of charge (PSOC)

A partially charged state is not the best alternative when it comes to lead-acid batteries. Lead-acid batteries don’t perform well if they are not properly charged. In such a scenario, lithium-ion batteries will be the best option that will work well in a partial state of charge. Melasta batteries are able to function properly even when they are in a charging state.

Capacity Utilization Compression

The typical Lead-acid battery is larger in size, however, they have lower energy density when contrasted to Melasta Li-ion battery. Melasta batteries offer 100percent of the claimed capacity and have a much lower self-discharge rate. They are more durable with high durability and reliability.

High Efficiency

Melasta batteries are extremely efficient, with an efficiency of 99% of charging and discharging. They are extremely resistant and can recharge much faster in comparison to traditional lead-acid batteries. Lead-acid batteries are able to achieve 60% capacity, and they have a lower recharge rate.

Maintenance Free

The most appealing thing about Melasta Li-ion batteries is they don’t require any maintenance, and no watering, and no corrosion. The self-discharge rate is extremely small for Melasta batteries. They also don’t lose capacity when they are idle and this feature can ensure that you have energy when you require it.

The Longest Life Cycle

Melasta has developed its batteries to meet modern standards of technology and manufactures them at the top of the line factories with the latest technology. Therefore, the life of our batteries lasts 10 years longer than conventional lead-acid batteries. Melasta batteries are still able to provide up to 85% to 80 percent of their capacity after completing the 2000 cycles. Therefore, it will reduce the replacements of your batteries for your appliances.

Green Energy

Melasta manufactures all batteries that meet international environmental and safety standards. It does not make use of any harmful material that could impact natural environmental conditions. Melasta is proud to supply renewable energy to the world.

Product Information


This 26650 Lithium Battery cell is part of our MB-LFP Battery cells series; Lithium Iron Phosphate chemistry makes these cells safer. The 3.2V 2900 mAh LFP cylindrical cell can be perfect for various commercial applications with high efficiency and super-fast charging and discharging. A long lifetime and fast charging capability are required. With a button terminal, the lithium iron phosphate battery offers numerous options for configuration. The battery can deliver 2000 cycles at 80% depth of discharge (DoD). This is a power cell. Power cells provide continuous current for a prolonged period, making them perfect for cycles like energy storage, electric mobility scooters, and many more.

26650 Battery Temperature

Melasta Lithium Battery cell is a more secure alternative to other battery technologies, such as LiCoO2 or manganese. We offer battery cells that are highly stable in chemical and thermal stability and discharge within temperatures ranging from -20 ℃ to 60℃.
