12V Lifepo4 100Ah Eza Bms 100/60A Bluetooth Lithium Battery

WHAT ARE THE REAL ADVANTAGES OF THESE BATTERIES?

Using a LiFePo4 can change life experience "electric" on the Camper.
First of all, their low internal resistance allows them to be charged with very strong currents.
If you have an energy source, for example the alternator with a special Battery to Battery Charger, for example, from 100A, you could charge the LiFePo4 from scratch in just one hour of travel (if it is a LiFePo4 with a 100A charge BMS), or in thirty minutes if you had already charged it to 50%. A huge advantage.
Conversely, the usable capacity: it is possible to request the same current from the battery, without voltage sag problems, up to almost 100% discharge.
This means that you can use a power inverter, without any problem (air conditioner, coffee machine, hair dryer, etc.)
Another huge advantage, the life cycles. a normal AGM after 500 cycles begins to show signs of "fatigue", while LiFePo4 last up to 10 times as much (5000 cycles with 50% depth of discharge)
To all this, we must add the weight, a good 100Ah AGM weighs about 30 kg, a LiFePo4 about 11/13 kg.

HOW CAN I RECHARGE THIS BATTERY?

The LifePo4s are charged substantially with the same sources as normal lead-acid batteries, but with different parameters.
For this, the solar regulator must have the preset configuration for LiFePo4 lithium batteries, or the correct parameters must be entered manually in the solar regulator.

The same goes for the 220V charger, it must have the setting for this type of battery.
If the LiFePo4 (Lithium) setting is not available, the old charger CAN NOT BE USED .

These are the typical values to be set manually on the solar controller, if there is no automatic configuration for LiFePo4:
Absorption voltage: 14 ,2 Volt
Absorption time: the shortest possible, zero is better
Equalization: if possible, eliminate this function, if not possible, set 14.4V
Bulk voltage: 14.0-14.6V.
Float voltage: 13.5V (in case of prolonged stop with recharge, lower to 13.3/13.4)
High Voltage Disconnect: 14.8 V
Functions such as desulphation will then be eliminated strong> and temperature compensation.

CAN I CONNECT THE BATTERIES IN PARALLEL?

These batteries are designed to be connected directly in parallel to each other (only with batteries of identical type and series), with the maximum number indicated in the specifications. NO PARALLERATORS, SWITCHES OR THE LIKE SHOULD NOT BE USED.
Paralleling is possible only with batteries purchased together and connected at the same time because they are connected together. over time the characteristics of the accumulator change causing a flow of current from the battery more new to the less new one.
It is not advisable to exceed the limit of batteries in parallel indicated in the specifications.

WHAT ELSE SHOULD I KNOW?

All LiFePo4 batteries deliver current up to the maximum allowed by its BMS.
So in the case of use with an inverter, if the limit is 100A, it can be absorbed by the inverter about 1100/1200 Watt.

LiFePo4 does not need battery chargers / maintainers: if it is not used it is always good practice to disconnect it with a battery switch and avoid completely discharged for long periods.

You must not use desulphators, devices designed only for lead batteries

It is not advisable to keep them always charged at 100% for long periods, unlike lead-acid batteries, this behavior can damage them.

One of the characteristics of LiFePo4 is to always supply the same energy both at 100% and at 30% of the own charge: therefore always having them fully charged does not always make sense, they have to charge and discharge.

Absolutely, do not use parallerators (Imanager, BDS180, etc. ) not dedicated to LiFePo4 batteries and absolutely not connected in parallel batteries of this type with others of a different nature.
