NEW version Box of Li-Ion 18650 batteries for Remote Control Transmitter (RC) JUMPER T12, supplemented with the mounting for the two charging boards 03962А. This box allows you to place and fix inside the case without deformation, two 18650 batteries with a diameter of not more than 18.5 mm, as well as two charging boards. See photo. I used a simple scheme of charging the batteries on two modules 03962А. A serial battery circuit is more reliable than a parallel circuit using a step-up voltage Converter. Since it eliminates interference from the boost Converter and the risk of failure of the Converter in the process of controlling the model. The serial connection provides high reliability of power supply of the transmitter. When the battery charges 03962А significantly heat up, especially if to protect them with heat-shrink tubing. And heating of circuit boards is not possible to use for fixing the hot melt adhesive. Made in the new version of fasteners for boards, allow them to securely fix and provide good cooling. See. photo. IMPORTANT, in this connection scheme, the batteries must be charged only in series, one by one !!! When connecting the micro USB cable to one charge module, the USB connector of the second module must remain free !!! See photo. You cannot charge two batteries at the same time, even from two different USB power supplies !!! See photo. Friends, all for good
