26700 Battery Cell Description:
EA Energy LiFePO4 battery use Automotive Grade LiFePO4 Cells with higher energy density, more stable performance and greater power.
Unlike the Lead Acid batteries, lithium iron phosphate lifepo4 battery has higher energy density and has longer service life
Smart Built-in BMS Protection:
BMS (Battery Management System) is like human brain to balance the voltage between battery cells in order to protect against over-discharge, short circuit, overcharge, overheating and overloading.
The battery uses imported original big brand ion batteries, with a small internal resistance, big capacity, cycle times and more, no memory effect, etc; internal circuit for multiple protection design, can prevent over charge, over discharge, over current; production process quality inspection and monitoring the use of computers to ensure superior battery performance.
the voltage is stable, far superior to ternary polymer batteries and lead acid batteries.
90% of the energy of the iron phosphate battery is concentrated in a small area of 3-3.2v, and the discharge characteristics are very stable.
Under normal condition use, li ion deep cycle battery provides the service life of 3000 - 7000 cycles while only 300 - 500 cycles for Lead Acid battery
lithium iron phosphate is strictly Safety tests do
All battery are UL listed to ensure quality
LiFePO4 deep cycle battery can be used in many places, such as travel trailer,boat,car audio,fish finder,camper van,solar panels,solar power, backup system,server rack,off grid application.
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..
