If you're building adapters, repairing chargers, or troubleshooting a dead pack, knowing the pinout is essential. HART 20V batteries (interchangeable with Worx Nitro and some Kobalt 24V—but double-check voltage) use a 4-terminal design under the main plastic slide. ✅ You CAN :
Knowing the pins is one thing. Knowing the behavior is better. ❌ You SHOULD NOT : | Terminal Label
