Advantages of lithium-iron-phosphate

The lithium battery offers a much better and longer service life than a lead battery:

– accepts deep discharges without damage (up to 90%)

– accepts high current draw without damage (up to 150A): coffee machine, microwave…

– accepts a very high charge current (more than 50A) and therefore allows a very fast charge

– very low self-discharge rate

– fire or explosion proof

Lithium batteries (lithium iron phosphate) offer many advantages over lead batteries.

They have a much faster charge capacity, which allows them to exploit the slightest ray of sunlight without being limited by the battery’s internal resistance.

A lead battery, depending on its capacity, will be limited in charging power. With lithium, you will charge with the maximum of what the controller can give.

Also, unbeatable when discharging, they easily withstand very fast discharges.

If you compare the price per available ampere hour (lithium has a very large depth of discharge) you will find that the price per available Ah is just a bit more expensive than lead batteries.

 

Why choose lithium iron phosphate batteries?

Lithium iron phosphate batteries are the safest of the traditional lithium-ion batteries. The nominal voltage of an LFP cell is 3.2 V (lead acid: 2 V/cell). A 12.8 V LFP battery consists of 4 cells connected in series, and a 25.6 V battery consists of 8 cells connected in series.

 

Why is a Battery Management System (BMS) needed?

1. An LFP cell will be damaged if the voltage on the cell drops below 2.5 V

2. An LFP cell will be damaged if the voltage on the cell is higher than 4.2 V. Lead-acid batteries can also be damaged if they are discharged too deeply or overcharged, but not immediately. A lead-acid battery will recover from a full discharge, even if it has been left in a discharged state for days or weeks (depending on the type of battery and brand).

3. The cells in an LFP battery do not automatically balance at the end of the charge cycle. The cells in a battery are not 100% identical. Therefore, after a cycle, some cells will be fully charged or discharged before others. The differences will increase if the cells are not balanced/equalized from time to time. For a lead-acid battery, a small current will continue to flow even after one or more cells are fully charged (the main effect of this current is the decomposition of water into hydrogen and oxygen). This current helps to fully charge other cells that are out of phase in their charging, and therefore it will equalize the state of charge of all cells. However, the current through an LFP cell, when fully charged, is close to 0, and cells that are out of phase will not be fully charged. These differences between cells can sometimes become very large over time, even if the overall battery voltage is within its limits, and some cells will be destroyed due to over- or under-voltage. Therefore, an LFP battery should be protected by a BMS system that will actively balance the individual cells and prevent over- or under voltage.
