Quick charge battery pack for NIKON flash units

I will sell a new (in the factory packaging) battery pack for Nikon flashes, I’ll give it for a symbolic 9,000 tenge - on ebay, Alibaba, these cost from 50 bucks A great thing for burst shooting with a flash - it charges very quickly It uses two groups of a symmetrical charging system and has more stable charging voltage. It charges time twice as fast. A new charging method is used. You get fast charging when using 8 AA batteries. This saves more than 25% power consumption in Standb-by mode compared to other similar products.
