KAVAN C50 Duo Charger with Balancer (2 × 250W)

KAVAN C50 Duo Dual-Channel Smart Charger 2 × 250W
The KAVAN C50 Duo is a compact, high-performance dual-channel smart charger designed for RC enthusiasts who demand versatility, power, and ease of use. Powered from a 10–30V DC source (car battery or regulated power supply), it supports virtually all common battery chemistries and features integrated 6-cell balancers for safe lithium battery charging.
Each channel delivers up to 250W of charging power, while Parallel Mode combines both channels to provide up to 400W and 16A for charging a single battery. A bright color LCD display and intuitive menu system make setup and monitoring simple and convenient.
