Review on 🔋 NOCO GENIUS2X4 Smart Charger: 4-Bank, 8-Amp (2-Amp Per Bank), Fully-Automatic Battery Charger & Maintainer for 6V and 12V Batteries. Includes Trickle Charging, Desulfator, and Temperature Compensation by Aaron Kindler

This is a great charger. Reconditioned my dirt bike's lithium battery and almost paid for itself. The only downside is that most of my bikes come with SAE fittings. However, with NOCO clamp cables, you can remove the clamps and replace the SAE connectors. In the end it's worth it. For other vehicles where wiring can be difficult, simply purchase an SAE adapter.
