Invicta Lithium LiFePO4 Battery SLIMLINE 12v 100Ah with Bluetooth – Battery Review

There is a whole storm of excitement these days about batteries as people are discovering the usefulness that they get from using lithium batteries. Whether it is their boats, their cars, or their camper vans, everyone is praising how good it is to finally switch from traditional lead-acid batteries towards their lithium counterparts. However, whether it is traditional lithium ion batteries like the ones you find in Tesla cars and power walls, or their larger alternatives called LiFePO4 batteries, you need to make sure that the one you are buying is reliable.


One of the popular options these days are the batteries by Invicta and the one we are reviewing here is certainly worth a look. This specific model has quite a few tricks up its sleeve, even when compared to other similar options. So, the question is if this thing any good. Read on to find out everything you need to know before making your purchase.



The reason people are shifting to lithium ion batteries from traditional lead-acid batteries even though they are becoming dirt cheap is their lifespan. The biggest flaw with lead-acid batteries is that they do not last for more than two years. However, with a longer lifespan as the biggest promotion point, there is a competition to be had. As for the Invicta Lithium LiFePO4 Battery, you can expect a great lifespan since it comes with a rating of over 200 charge cycles, that too with 100% DoD. Even if you ran through a complete cycle every two days, the battery would keep on working for at least 10 years! Thanks to an integrated BMS, your cells get optimum charging and discharging which is key to a long battery life. The amperage it can deliver is also industry-leading with 95 Amps discharge, where most other lithium ion batteries only providing up to 50 Amps.



Depending on the application that you are going for, the strength of the battery’s body makes a big difference. This LiFePO4 comes in a heavy-duty ABS case that can withstand pretty much any normal application including campers, off-road vehicles, caravans, and even as portable power supplies. You can use them without worrying about any damage under all these circumstances. However, the ABS case being plastic means it can deform a bit if you put too much strain on the casing or are exposed to temperatures about 90°C. The chances of that happening are close to none in most cases, so there is nothing to worry about.


Solar Application

The most obvious use case of any type of lithium ion batteries these days is solar power. Depending on the system you have, you may want to connect the batteries in different configurations. However, voltage is a key part of the system and keeping things balanced is critical for this LiFePO4 battery. You can connect it in series up to 4 times, thereby providing a 48V system which the most common in solar systems. However, the battery must be from the same production batch and have the same model to ensure that there are no problems. As for the capacity, you can also connect as many as four batteries in parallel, effectively giving you a system of 400AH capacity.


Ease of Use

As far as installation and use are concerned, you can get these lithium ion batteries installed without a hitch. The BMS works automatically and does not require any wiring to systems. Two clear terminals for positive and negative are present on the body and you can connect them easily in any space. The slim size of this specific model also makes it easy to install this battery in tighter spaces like you would find in camper van, caravans, and even some boats. In case you need to use custom connectors for the battery, the terminals have M8 bolts installed on them which can easily be removed. Otherwise, they are compatible with most systems that support LiFePO4 batteries like this one. As for the weight, the battery weighs only 13kg which is a big upgrade from any lead-acid battery and also one of the lowest in similar lithium ion batteries.


Protection Features

Every battery in this model comes with a built-in BMS that protects it from a range of different problems. This includes overcharge protection, over-discharge protection, individual cell capacity management, temperature protection, and remote management as well. The battery also comes with the Redback™️ Lithium Operating System which protects it efficiently by monitoring its stats constantly. The battery also comes with a safe mode that ensures that your battery does not become dangerous due to any problems that may be present in your system.


Weather Protection and Operating Range

This battery does have the strong build quality, but it does not come with any weather protection features. The case is not waterproof and should not be exposed to moisture or water. Proper sealed installation needs to be ensured to avoid any incidents. The battery also has a charge temperature range of 0°C to +45°C and a discharge range of -20°C to +60°C. In case the battery is not being used, you can store it at a temperature between -10°C and +45°C.



Being from Invicta’s smart battery line-up, this battery also has built-in Bluetooth support, allowing you to monitor it using their smartphone app. The application provides information on battery capacity, voltage, power level, and health as well. This is extremely convenient if your batteries are installed in a location that is not easy to reach. It also allows you to make sure you do not run out of power at a time when you may need it the most.



Lithium ion batteries may seem like a considerable investment but you get your money’s worth for sure once you start using them. As for the Invicta Lithium LiFePO4 Battery SLIMLINE 12v 100Ah with Bluetooth, we think it is certainly a worthwhile investment and if you are looking to create a reliable solar or camping setup, this battery will easily prove to be a worthy companion.
