										<content:encoded><![CDATA[<p>The SUNESS Lithium Ion Battery has the following feature;</p>
<p>HIGH TEMPERATURE RESISTANCE<br />
The peak value of lithium iron phosphate electric heating<br />
can reach 350℃-500℃, while lithium manganate and<br />
cobalt acidLithium is only around 200°C, with a wide<br />
operating temperature range (-10℃&#8211;55℃) .</p>
<p>ENVIRONMENTAL PROTECTION<br />
Lithium iron phosphate batteries are generally considered<br />
to be free of any heavy metals and rare metals (the nickel<br />
-hydrogen battery requires rare metals), non-toxic (SGS<br />
certification), pollution-free and meets European RoHS<br />
regulations, and is an absolute green battery.</p>
<p>BMS CONTROL<br />
The battery management system monitors<br />
and adapts to battery conditions to maximize<br />
performance and safety</p>
<p>LONG CYCLE LIFE<br />
At 80% depth of discharge, the number of<br />
cycles exceeds 6,000, and a 5-year warranty<br />
is provided.</p>
<p>HIGH SECURITY<br />
The P-O bond in the lithium iron phosphate crystal<br />
is stable and difficult to decompose. Even at high<br />
temperature or overcharge, it will not collapse and<br />
generate heat like lithium cobalt oxide or form strong<br />
oxidizing substances, so it has good safety.</p>
<p>LIGHT WEIGHT<br />
The volume of a LiFePO4 battery with the same<br />
specification and capacity is the volume of a lead-acid<br />
battery,the weight is 1/3 of the lead-acid battery.<br />
Allowing for simple installation and transportation.</p>
