This project has me creating a battery box for my Heated Motorcycle GLoves for Winter Driving. The standard battery box that came with the gloves only support 3 1.5 volts AA alkaline Batteries or 1.2 volt rechargable batteries which only lasted 2 to 4 hours.
These new batteries will last 4 to 8 hours.

The batteries i am using came 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

The Heated Gloves came from ebay as well from here: 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

The Battery connectors are also from ebay from here: 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 battery pack that came with it only supported 4.5 volts, these other batteries i am using are 7.4 Volts at 2100mah
Just screw in 2 3mm screws to hold battery in place and connect to gloves with the XT60 Plugs.
