Why Voltagen
More value. Better engineered.
| Feature | Voltagen | Typical 12V systems |
|---|---|---|
| Cell chemistry | Automotive-grade NMC lithium-ion — the chemistry used in EV and hybrid drivetrains. | Consumer-grade LFP, the same cells used in lead-acid replacement batteries. |
| System voltage | 58V architecture. Four times the output of a 12V alternator the same physical size. | 12V. Heavier cable and more space for the same delivered power. |
| Charging | Secondary alternator at 6,900W–11,000W. Most systems recharge in under two hours while driving. | Shore power and solar, with limited alternator charging. |
| Energy density | High-density, low-mass packs from 6.9kWh to 100kWh+. Built for vehicles where space is the constraint. | More weight and volume for the same stored energy. |
| Fitment | Coach-specific retro kits with the harness, mounting and connectors already worked out. | Generic components. The installer fabricates the interface. |
| Service & support | Factory service in Holland, Michigan — including systems built before we acquired the line. | Varies by installer. The original manufacturer may no longer support it. |
