The U.S. Consumer Product Safety Commission said the positive and negative leads are wired incorrectly. Charging or using the batteries can result in overheating, the commission said in a statement.
The batteries are used to power Horizon Hobby's Losi Mico remote control vehicles. They were sold separately from the vehicles from December 2012 through April 2013 for about $20.
Consumers were advised to stop using the batteries and disconnect them from either the remote control or the charger. They should then be returned to Horizon Hobby for a full refund, the commission said.
Consumers can call 877-504-0233 for information.
