12 Volt 24ah Lithium-Ion Lifepo4 Deep-Cycle Battery For Computers Servers
12 volt 24ah lithium-ion Lifepo4 Deep-cycle Battery for Backup Power CCTV ATM Emergency Lighting Computers Servers
Why are LiFePO4 Lithium Battery Pack viable alternative to lead-acid batteries?
Because of the nominal 3.2 V output, four cells can be placed in series for a nominal voltage of 12.8 V. This comes close to the nominal voltage of six-cell lead-acid batteries. Along with the good safety characteristics of LFP batteries, this makes LFP a good potential replacement for lead-acid batteries in applications such as automotive and solar applications, provided the charging systems are adapted not to damage the LFP cells through excessive charging voltages (beyond 3.6 volts DC per cell while under charge), temperature-based voltage compensation, equalisation attempts or continuous trickle charging. The LFP cells must be at least balanced initially before the pack is assembled and a protection system also needs to be implemented to ensure no cell can be discharged below a voltage of 2.5 V or severe damage will occur in most instances.
