Benefits of lithium iron phosphate

The lithium battery offers a much better quality of service, and this longer than a lead battery:

- accepts deep discharges without being damaged (up to 90%);

- accepts large current calls without damaging (up to 160A): coffee maker, microwave ...

- accepts a very large charging current (more than 50A) so allows very fast charging;

- very low self-discharge rate

- Anti fire or explosion security

Lithium batteries have many advantages.
High number of charge / discharge cycles:

    Service life at 80% of the depth of discharge (DoD)> / = 3000
    Lifespan at 50% of the depth of discharge (DoD) LiFePO4 battery> / = 4500

Lightweight, powerful and offering a very long lifespan, this Lithium-ion battery particularly suitable for cyclic uses, when the batteries are frequently charged and discharged.

Integrated BMS. 100% of the capacity is available for your needs, without voltage drop!

Lithium batteries (Lithium Fer Phosphate) offer many advantages compared to lead batteries.

They have a much faster charging capacity, which makes it possible to exploit the slightest ray of sunshine without being limited by the internal resistance of the battery.

A lead-acid 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.

Unbeatable also during discharge, they easily support very rapid discharges.

By comparing the price per hour available (we have a very large discharge depth with lithium) we see that the price per Ah available is just a little bit more expensive than lead-acid batteries.

Why lithium iron phosphate batteries?

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

Why is a Battery Management System (BMS) necessary?

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 more than 4.2 V. Lead-acid batteries can also be damaged if they are discharged too deeply or if they are 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 the brand).

3. The cells of an LFP battery do not balance automatically at the end of the charge cycle. The cells in a battery are not 100% identical. This is why, 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 slight current will continue to flow even after the full charge of one or more cells (the main effect of this current is the decomposition of water into hydrogen and oxygen). This current helps 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 the phase shifted cells will not be fully charged. These differences between cells can sometimes become very large over time, even if the general battery voltage is within its limits, and some cells will be destroyed due to overvoltage or undervoltage. Therefore, an LFP battery must be protected by a BMS system which will actively balance the individual cells and prevent overvoltage or undervoltage.
