Sodium-ion at the core
Dura Start focuses its R&D on sodium battery materials, battery packs and battery management, positioned as the successor to lead-acid starter batteries.
- 70C instant discharge (≤2s) @25°C
- 40C max continuous discharge @0–45°C
- Charge: 14.8V ±0.2V, CC/CV
03 / Intelligence
A BMS that thinks ahead
The battery management system handles discharge, temperature, faults and communication, and estimates state of charge using ampere-hour integration, OCV correction and Kalman filtering.
- Over-charge and over-discharge protection
- Over-current and short-circuit protection
- High- and low-temperature protection, cell balancing
