Vault Power Element 11 NA-59HP — 58.5Ah Sodium-Ion Battery
The physical Vault Power battery is labeled Element 11 NA-59HP, and its original case ratings need to stay separate from the newer NA-60. Vault prints 12V, 58.5Ah and 702Wh on the battery, along with 400A charge, 600A discharge and a 16V maximum-voltage figure.
The 58.5Ah / 702Wh rating tells us this is a substantial stored-energy battery, not a small voltage-support add-on. In a high-output audio system, that reserve can supply current when amplifier demand rises above what the alternator is producing in that instant. It still has to be recharged afterward. If the charging system cannot replace the energy being consumed over time, the battery will eventually discharge no matter how large its reserve is.
Vault’s 600A published discharge figure is another reason to evaluate this model as part of a serious current path. A large monoblock or multi-amplifier system can demand hundreds of amps, and the battery, alternator, power wire, grounds, fuse protection and distribution all need to be capable of supporting the same load.
The 400A charge marking needs a careful interpretation. It is the charge rating Vault printed on the NA-59HP case. We do not call it a 400A maximum-alternator rating because Vault’s current Element 11 product data separates “charging” from “maximum alternator charging.” If this battery is being paired with a high-output alternator, the charging strategy should be verified around this exact model rather than borrowing the newer NA-60’s alternator number.
The case also states 16V maximum. Maximum is not target voltage. If the electrical system is operated at elevated voltage, every amplifier, DSP, vehicle module and accessory on that bus has to tolerate the same voltage—not just the battery.
NA-59HP and NA-60 are close in capacity but not identical in published electrical ratings. NA-59HP is 58.5Ah / 702Wh with 400A charge and 600A discharge printed on the case. Current NA-60 data is 60Ah with 240A charging, 360A discharge and a separate 350A maximum alternator-charging specification. Use the rating set for the battery actually being installed.
Choose NA-59HP when the build already uses this earlier Element 11 platform and its original 58.5Ah / 600A-discharge rating fits the electrical design. If the job is being designed around a current Vault battery and needs current manufacturer alternator guidance, compare NA-60 or NA-100 instead.
