First impression / Première impression

First impression: TEMGOT 12V (12.8V) 100Ah LiFePO4 Battery, Built-in Low-Temp Heating Function

I just installed 2 Temgot batteries. (serial installation)
I appreciate the touchscreen on the top, it’s easy to check.
The app (on my iPhone) works very well via Bluetooth. You can read the voltage of each cell, the number of cycles, and other useful information.
I like the fact that you can disable charging and discharging directly on the touchscreen or through the app.
As for the heating function, I haven’t tested it yet since the cold hasn’t arrived in Canada, but it shouldn’t take long. To be continued.

Première impression :
Je viens juste d'installer 2 batteries Temgot. (installation en série)
J’apprécie l’écran tactile sur le dessus, facile à consulter.
L’application (sur mon iPhone) fonctionne très bien en Bluetooth. Il est possible de lire la tension de chacune des cellules, le nombre de cycles et d’autres infos pertinentes.
J’aime le fait de pouvoir désactiver la charge et la décharge directement sur l’écran tactile ou sur l’application.
En ce qui a trait à la fonction chauffante, je n’ai pas encore testé, le froid n’est pas encore arrivé au Canada, mais ça ne saurait tarder. À suivre.
FAQs

How does the self-heating feature help in Canadian winters?
The built-in heating system helps prepare the 12V 100Ah LiFePO4 Battery for charging in cold conditions. When the battery is connected to a charger and the temperature is below 0°C (32°F), heating starts automatically and stops at 5°C (41°F).

Can this 12V 100Ah Lithium Battery be charged below freezing?
Yes. The self-heating system is designed for cold-weather charging. When charging begins below 0°C (32°F), the battery heats itself first and resumes normal charging after reaching 5°C (41°F).

What does 12.8V mean on a 12V LiFePO4 Battery?
The 12.8V rating is the nominal voltage of a four-cell LiFePO4 battery, with each cell rated at 3.2V. It is still considered a 12V battery because it is designed for standard 12V power systems.

How much usable energy is available from the 100Ah capacity?
The battery is rated at 100Ah and 12.8V, providing 1,280Wh (1.28kWh) of nominal energy. Its 100% usable capacity makes it suitable for a wide range of 12V applications.

What charging voltage does this 12V battery require?
For proper charging, use a LiFePO4-compatible charger with an output of 14.2–14.6V. The recommended charging current is 20A.

Is this battery a good choice for RVs, campers, and off-grid power?
Yes. The 12V 100Ah LiFePO4 Battery is designed for RVs, campers, marine systems, solar storage, off-grid setups, and other compatible 12V applications.

Can I use this battery with a trolling motor?
Yes. It is designed for compatible trolling motors rated at 30–70 lb thrust. It should not be used as a starter battery or for golf carts.

How do I check battery information without a multimeter?
The built-in touchscreen and Bluetooth App provide convenient battery monitoring. You can check information such as voltage, temperature, cycle count, and other operating data directly from the display or your phone.

Can I see the voltage of each battery cell?
Yes. The monitoring system can display the voltage of the individual cells, helping you keep track of battery condition and cell balance.

How long is the expected life of this 12V 100Ah LiFePO4 Battery?
The battery is designed for up to 5,000 charge cycles and up to a 10-year lifespan under appropriate operating conditions. Actual service life depends on usage, temperature, charging habits, and discharge depth.

Can I expand a 12V 100Ah battery system?
Yes. Multiple batteries can be connected in series and parallel, with a maximum configuration of 4P4S. This supports 12V, 24V, 36V, or 48V systems and allows you to increase overall storage capacity.
