UN38.3 Lithium Battery 12 Volt 150Ah Lithium Ion Battery For Electric
Wheelchair
RJ 12V Lithium battery is made with LiFePO4 batteries cells. The
rated voltage of lifepo4 cell is 3.2v, 4 battery cells in series
for a 12.8v rated battery pack. Compared with traditional lead acid
batteries, or Gel battery, or Gel battery, 12V lithium iron
phosphate battery is the most efficient of all kinds. RJ offers a
whole line of 12 volt lithium batteries with various capacity from
10ah up to 800ah for applications in RV’s, electric marine Boats,
EV's and off-grid solar household applications and so on. high
performance of the 12 v lithium battery make sure you power
everything you want to in the system.
much Longer life span, means more recreation time with the RJ 12v
lithium battery. This 12V lithium battery deep cycle lithium
battery is the best solution for replacement of a group 31 AGM, GEL
or lead-acid Battery. Lighter in Weight, smaller in size makes it
the best substitute to replace the lead-acid and become one of the
most popular lithium batteries ever used in RV fans, Campers,
Boats.
The 12V lithium battery is more compact and more powerful gel or
AGM or lead acid battery. Charging at Max 1C rate, discharging at
max 2C rate, which makes it a excellent combination of dimension
and capacity energy for wide applicationss such as , RV, marine,
solar energy systems etc.
RJ 12v lithium batteries offer much more energy for high
consumption than lead-acid or AGM or gel batteries. Also more high
efficiency of discharge and charge round trip, it is up to 98.5%,
and it can be discharged to 100% depth of discharge. Which means we
do not have to leave a extra energy in the battery, on the
contrary, every energy we charge the and store in the battery can
be drawn out for use. If you buy a 12v lithium battery rated at
200ah, then with 100%DOD, you can discharge it to a totally energy
of 12.8v * 200ah, which is 2560wh.
unlike other 12v lithium batteries in the market, which you will
find out that their lithium battery are not made equally.therefore
the consistency of it is very poor. RJ 12v lithium battery adopt
high quality and high consistency battery cells to avoid this and
make sure high consitency is possible. Our 12v lithiumbattey is
made with a built-in Battery Management System (BMS), The BMS
manage and protects the 12v ltihum battery with high-accuracy State
of Charge (SOC) calculations. Over charge, over discharge , short
circuit or over currrent all can be avoided by cut off the load
when single cells of the 12v lithum battery reach a high voltage of
3.65v and a low voltage of 2.5v.
