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..
