It
is a LiFePO4 battery (lithium iron phosphate), so its internal technology has
all the advantages inherent in the latest generation lithium batteries. The
Nexus 4.8kWh lithium battery is of high energy density and light weight
compared to other batteries in the market with similar technical
characteristics. Its internal technology enjoys a long service life even when
its usual use of deep cycles. It is a battery with a fast charge capacity
compared to other batteries of a similar range, so waiting times are minimized.
The Nexus 4.8kWh lithium battery has an integrated battery management system
(BMS) that by controlling the temperature, voltage, etc. guarantees both the
safety of the accumulator and the integrity of the other connected elements,
optimizing Battery operation at all times. The battery has RS485 ports to make
connections in parallel and thus increase the capacity of the system, in
particular up to 8 batteries can be connected in parallel, one of them being
the master and the other 7 slaves. The front of the battery incorporates an LED
light that indicates the percentage of remaining energy autonomy. The Nexus
4.8kWh battery has a low self-discharge rate and no memory effect. This battery
does not emit gases during operation or at rest, which allows you to install
the battery inside the home if you wish. Since it is a lithium battery, it does
not require maintenance or periodic control of its internal levels.
