Description: It supports the combined use of 3 sets of parallel charging boards, which can charge 18 sets of batteries of the same nature at the same time. The charging time is only that of a single battery, thus saving charging time. The overall voltage value after the multi-chip monomers are balanced with each other is more balanced, and the average voltage difference is smaller; the balance efficiency of the charger is improved and the balance time at the end of the charge is shortened. At the same time, it avoids overcharging of individual cells, thus improving balancing efficiency and greatly shortening the later stages of the balancing charge cycle. Made of premium plastic material, the battery charger is eco-friendly, safe and durable. The length of the product is about 13.8cm, the width is about 6.7cm, and the height is about 1.7cm. Suitable charging for RC car and RC boat battery.
