Advantages of lithium iron phosphate batteries:
First of all, lithium batteries are three times lighter than acid batteries for the same amount of energy. They are now very popular in all mobile systems, including electric boats, which are taking over our lakes and rivers. As opposed to boats who use acid batteries, electrical boats equipped with lithium batteries are more economical, less polluting and clearly better for the environment.
Moreover, lithium batteries have a superior efficiency as opposed to acid batteries. While they have an efficiency of about 80%, lithium batteries have an efficiency of 98%**. Furthermore, the lithium-ion battery’s capacity is clearly superior to the acid battery’s one. Therefore, two batteries with the same 12V capacities of 100Ah won’t enable the same extraction: about 1000Wh of the lithium battery for only 500Wh for the acid one.
Speaking about power, it has been demonstrated that the lithium battery accepts charges much more important than an acid battery. The same applies for its lifespan. The lithium battery has a life cycle 4 times longer than the acid one for an identical usage.
EA 12.8V 21Ah 268Wh LifePO4 Lithium Iron Phosphate Battery is the ultimate in weight versus power technology. This is a drop in replacement for your Lead-acid battery, and will require no change to your stock charging system.
The lithium battery’s unique built-in Battery Management System (BMS) protects it from overcharge, deep discharge, overloading, overheating and short circuit, and excessive low self-discharge rate ensuring up to 1 year maintenance-free storage.
We can also customize any size and function you need.Such as 12V/24V/36v/48v/60V/72v 20AH, 50AH,100h, 120ah, 150ah,200ah, 300ah, 400ah, 800ah etc..
