AC/DC adaptor (Charger) with Tamiya connector
How do you calculate the charging time: ( Battery pack capacity (mAh) / 800mAh ( charging speed) ) * 1.3 (coefficient) For example: 7.2V 3000mA NIMH battery pack (3000/800) *1.3 = 4.9 ( hours ) It takes 4.9 hours to charge a 7.2V 3000mAh battery pack from empty to a fully charged status. Coefficient number (1.3) is to count for charging inefficiency due to energy loss through connectors, wire, heat.
