Battery Box for Heated Gloves

myminifactory

I'm upgrading my Heated Motorcycle Gloves for Winter Driving by creating a custom battery box that can handle higher voltage batteries. The standard battery pack provided only supported 3 x 1.5V AA alkaline batteries or 1.2V rechargeable batteries, which lasted between 2 to 4 hours. In contrast, the new batteries I've sourced from eBay (https://www.ebay.com/itm/Kastar-Battery-LCD-Charger-for-Olympus-BLS-5-PS-BLS5-BLS-50-Olympus-OM-D-E-M10/253514057274?ssPageName=STRK%3AMEBIDX%3AIT&var=552699213750&_trksid=p2057872.m2749.l2649) will last 4 to 8 hours. These batteries from eBay (https://www.ebay.com/itm/Kastar-Battery-LCD-Charger-for-Olympus-BLS-5-PS-BLS5-BLS-50-Olympus-OM-D-E-M10/253514057274?ssPageName=STRK%3AMEBIDX%3AIT&var=552699213750&_trksid=p2057872.m2749.l2649) have a higher capacity of 7.4V at 2100mAh, which is more than double the voltage of the original battery pack's 4.5V. To assemble the custom battery box, simply screw in two 3mm screws to secure the battery in place and connect it to the gloves using XT60 plugs from eBay (https://www.ebay.com/itm/10-Pairs-XT60-Male-Female-Bullet-Connectors-Plugs-for-RC-Lipo-Battery/123434697447?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649). The Heated Gloves themselves came from eBay (https://www.ebay.com/itm/Electric-Battery-Powered-Touchscreen-Winter-Hand-Warm-Heated-Gloves/264015993516?ssPageName=STRK%3AMEBIDX%3AIT&var=563547975941&_trksid=p2057872.m2749.l2649).
