🔗 Connection Combinations (What works with what?)
- Detailed View: See the Extra Battery Compatibility Matrix.
- Delta Series:
- Delta 2 -> [Delta 2 EB] OR [Delta 2 Max EB]
- Delta 2 Max -> [Delta 2 Max EB] OR [Delta 2 EB] OR [Delta Max EB]
- Delta Pro -> [Delta Pro EB] (Proprietary)
- Delta Pro 3 -> [DP3 EB] OR [DP EB] (via Adapter)
- River Series:
- River 1 (Original) -> Modular “Bolt-on” battery module.
- River Pro -> Specific [River Pro EB].
- River 2 Series -> NO expansion ports. Must use PowerStream or solar for capacity buffer.
- River 3 Plus/Max -> Supports specific R3 Extra Battery.
2. Charging Combos
- Alternator Charger (800W) -> Works natively with Delta 2, Delta 2 Max, Delta Max (XT150).
- Adapter needed for: Delta Pro, Delta Pro 3.
- PowerStream -> Works with ALL Delta and River units.
- Efficiency Tip: Use BKW-DeltaPro cable for best power throughput (600W-800W).
3. Smart Generator Auto-Start
- Supported by: Delta Max, Delta Pro, Delta 2 Max, Power Kits.
- Cable: Uses the Extra Battery port cable (with data pins).
⚠️ Safety Warning: No Station-to-Station
NEVER connect two power stations together using the Extra Battery (XT150) ports (e.g., Delta 2 to Delta Max). These ports are designed for passive battery slaves. Connecting two active “Masters” will lead to back-feeding, BMS damage, or fire.
🛠 Hackable Pairs
- Delta 2 + Generic 48V Server Rack Battery: Possible via “Resistor Hack” (See Hardware Mods).
- EcoFlow BLADE EB: The robotic mower extra battery is actually a high-quality LFP battery compatible with Delta 2.
- EcoFlow 5kWh LFP Battery + Victron Inverter: Possible via Polarity Adapter (AB-CONV-PLUG).
