Vault Power Element 11 NA-20 — 20Ah Sodium-Ion Battery
The NA-20 is the compact Element 11 battery we would look at when the system needs more electrical reserve but space, weight and charging-system size still matter. It is not simply a smaller NA-60 or NA-100. Vault gives this model its own charging, discharge and alternator limits, and those numbers are what should decide whether it belongs in the build.
Vault publishes the NA-20 for vehicle, motorcycle and powersports use, with 20Ah capacity in a 6.5 x 4.94 x 6.88-inch case that weighs 6.4 pounds. That packaging is a major reason it makes sense on motorcycles, UTVs and compact vehicle installations where a larger battery can create more fitment problems than it solves.
For application sizing, Vault publishes support for up to 5,000 watts in vehicle systems and up to 3,000 watts in motorcycle/powersports systems. We do not treat those wattage figures as a universal guarantee. Two systems with the same amplifier rating can have very different electrical demand depending on amplifier efficiency, actual current draw, alternator output, listening duty cycle, cable, grounds and how the vehicle is charged. The battery still has to be selected as part of the complete electrical system.
The charging side is where the NA-20 really separates itself from the larger Element 11 batteries. Vault publishes 80A charging, 120A discharge and a 220A maximum alternator-charging figure. If the vehicle has a high-output alternator that can exceed the battery’s intended charging capability, choosing the NA-20 only because it is small is the wrong way to make the decision. The NA-60 raises Vault’s published maximum alternator charging to 350A, while the NA-100 raises it to 600A and adds much more stored capacity.
Vault also publishes a 6–16V operating range and active balancing. Active balancing helps manage the internal cell relationship, but it does not replace correct charging-system setup. The alternator still has to replenish the energy the amplifiers and accessories consume, and the power/ground wiring and fuse protection still have to support the current safely.
For external charging, Vault states that an AGM or lithium battery charger may be used. We would still confirm the charger’s actual voltage/current behavior rather than assuming any charger with one of those labels is automatically correct at every setting.
Choose the NA-20 when the build benefits from its compact 6.4-pound package, the charging system stays within the battery’s published limits and 20Ah is the right amount of reserve. Move to the NA-60 or NA-100 when the alternator, sustained load or required stored energy calls for a larger electrical platform. Bigger is not automatically better; correctly matched is better.
