Anti-reverse polarity protection with color-coded silicone cable and an aerospace-grade honeycomb heat-dissipation design delivers stable performance under heavy loads. This XT90 parallel charging board exceeds standard parallel boards with higher current capacity and patented thermal management, keeping temperatures lower during full-load operation compared with traditional copper interfaces. Designed for hobbyists and FPV racers who need fast, safe charging of multiple packs, whether you are a pro or a beginner managing several batteries. The XT90 parallel charging board enables intelligent current distribution to charge four packs simultaneously, with gold-plated connectors and resistance under 0.5 mΩ, reducing heat generation by about 60%. Use scenarios - FPV race pit stop: quickly top up four LiPo packs while maintaining safe temperatures. - Home workshop: parallel charge multiple batteries for spare packs with balanced, safe charging. - Field trips: portable four-pack charging to support extended flight sessions.
