The LiPo batteries for the Kysho dNano micro RC models are originally intended to be charged with a dedicated NiMH battery powered charger. Although that may be convenient at times due to its compact size and mobility it offers it is not easy to charge the batteries using a dedicated LiPo charger. We have designed a simple 3D printable battery charging adapter for the Kyosho dNano LiPo battery to allow the battery to be charged on a multifunctional charger such as the Imax B6AC or another popular choice. Do note that there is a part that you need to 3D print and there are some additional parts that you would require to make yourself this simple DIY battery charger for dNano.
More instructions on how to assemble the charging adapter after you 3D print the battery holder part are available here: http://minirc-project.com/63-battery-charging-adapter-for-the-kyosho-dnano-rc-model/
