Victron Lifepo4 Smart 12 Battery 8v 100ah

VICTRON LiFePO4 SMART BATTERY 12.8V 100AHAlithium iron phosphate batteries (LiFePO4 or LFP) are the safest of lithium-ion batteries.

The nominal cell voltage in LiFePO4 12.8 V is 3.2 V (lead-acid 2 V / cell) and the entire battery consists of 4 cells connected in series.

Distinguishing features of the product:

Integrated cell balancing function

Possibility of parallel and series connection

Possibility to monitor cell voltage and temperature using an application via Bluetooth (Android, iOS, Windows)

Energy efficiency at every charge level is 92%

Flexible charging voltage level

Efficiency

In some applications (off-grid systems or wind farms), energy efficiency may be crucial. This round-trip efficiency (discharging from 100% to 0% and charging from 0% to 100%) for an average lead-acid battery is 80%. The energy efficiency of LiFePO4 batteries in both directions is as high as 92%.

The charging process of lead-acid batteries becomes particularly inefficient after reaching 80% of the state of charge, which results in an efficiency of 50% or even less, which may be a problem in the case of off-grid PV systems, where an energy reserve of several days is required. If LiFePO4 batteries are used, they will still achieve 90% efficiency even in high discharge conditions.

Monitoring

Thanks to modern technology and Bluetooth connectivity, you can monitor the temperature, charge level and battery status in an application available for every platform.

LiFePO4 requires one of the following BMSs for proper and failure-free operation:

VE.Bus BMS - recommended for systems with a Victron inverter/charger

miniBMS - recommended for small installations

BMS Battery Management System 12/200 – recommended for use in car and yacht installations with DC receivers and alternators

Smart BMS CL 12/100 – recommended for use in car and yacht installations with DC receivers and alternators

LiFePO4 batteries do not need to be fully charged to operate efficiently and for a long time. They do not lose their efficiency. Therefore, they work well in places where they are not constantly used, e.g. in caravans, campers on boats or in summer houses at different times of the year. Other advantages include a wide range of operating temperatures, high efficiency also in winter, excellent cyclic parameters, low internal resistance and high energy efficiency. LFP batteries are perfect for use in places with very demanding conditions.
