Flex Battery

If you’re looking for a power station to use in extreme environments, or you just want a military-spec power station, the Flex Tactical is for you. The Flex Tactical has many features and protections not found in any of our other systems.

We designed the Flex Tactical for heavy-duty use in extreme environments. Use this power station to power your adventure equipment, or even your devices and appliances at home when the grid goes down.

Yes! The pure sine wave inverter is designed to provide up to 80% of a single Flex Battery's capacity at a continuous 1,500-watt discharge under normal operating conditions before shutting down to protect the batteries and the inverter. As with any lithium battery, regularly drawing the maximum output continuously will affect the life of your Flex Batteries, but the power is there!

Yes! You can use our EC8-to-MC4 adapter to connect third-party arrays in parallel, series-parallel, or series arrangements (as long as you don’t exceed 90VOC/30A max input).

Not all lithium battery cells are equal. Some manufacturers use cheap cells, with very few safety features. The cells we use in our Inergy battery designs go through an extensive 3rd-party testing process, and we tightly control our sources. Li-LFP and Li-NMC batteries are required to pass the same safety standards just to be able to ship them.

We don't change battery manufacturers often OR lightly, with any changes we make going through our FULL re-certification and validation process. Our batteries contain a wide array of protections, from the cell level to the BMS (battery management system). Our batteries are some of the safest on the market, thanks to our in-house, proprietary, USA-designed BMS and batteries.

These days, almost every EV car and truck uses Li-NMC. It just isn't possible to get the range consumers demand from Li-LFP batteries. This caused a rapid advancement of Li-NMC safety technology across the market to meet the needs of the automotive world. Being a portable system, the Flex Tactical makes use of high-density Li-NMC chemistry to achieve some of the most energy-dense batteries on the market. Other chemistries such as Li-LFP and lead-acid/AGM are much heavier, much larger, and (in the case of Li-LFP) more expensive. Li-LFP does have its advantages, especially in permanent DIY installations or rapid charge/discharge applications. They offer higher cycle life counts and have some enhanced safety by volume, but are usually not ideal for portable solutions due to the extra weight and space needed for these benefits. In fact, many manufacturers use Li-LFP in order to loosen their safety standards, meeting the same requirements of Li-NMC batteries but not exceeding them. Li-NMC offers the highest energy density and, with the Flex system's advanced safety features, is lighter and more compact than other battery chemistries without sacrificing safety.

Yes! You can charge your Flex Tactical system from grid AC power, solar panel arrays, and even your vehicle's cigarette lighter port simultaneously (with accessories as required).

The Flex Tactical is backwards-compatible with our standard Flex modules, with some exceptions (due to the latch system changes). Regular Flex modules can attach to the bottom of your Flex Tactical system and latch together, but Tactical modules cannot latch to regular Flex modules. They'll work together, but you won't be able to transport them together as a single unit like this. For instance, you canattach regular Flex batteries to the bottom of a Flex Tactical system and they'll latch together, but you cannot latch a regular Flex power console to Flex Tactical batteries, preventing carrying/transportation. However, the Flex Tactical features are unique to the Tactical modules, so using regular Flex modules may affect/disable some features of the Tactical system (such as IP52 dust/water protection).

For more advanced/permanent applications, the earth ground connection gives you the option to connect your Flex Tactical system to an earth ground (buried metal pipe, grounding rod, etc.), providing a true earth ground to your AC and DC outlets. This grounding also provides enhanced EMP, EMC, and surge protection to your Flex Tactical system. We suggest you use a 10AWG wire when using this connection.
