Frequently Asked Questions — Motorcycle Audio
Do I need to upgrade my stator?
For basic speaker/amp upgrades, stock charging is often fine. For multi-amp or demo setups, a high-output stator helps maintain voltage and headroom.
Is sodium-ion safe on a motorcycle?
Yes. Sodium-ion packs are designed for stability and value. Use a compatible smart charger and follow proper wiring and fusing practices.
Will I hear a difference?
Stable voltage reduces clipping and keeps your amps performing consistently, so your system sounds cleaner at highway speeds and during shows.
Can I use my lithium charger?
Yes — Vault notes the NA-20 can be charged with AGM or lithium smart chargers. Avoid long-term trickle chargers meant for lead-acid storage.
Is it lighter than AGM?
Yes. Around 6.4 lb, it’s significantly lighter than comparable AGM batteries, reducing weight and improving handling.
