Description

I am selling battery replacements for MTH Proto-Sound 2.0 *3-Volt* Engines. This replaces the 2.4v AA (blue) or AAA (green) battery packs
I have included a picture of a tender with the charging port of a 3-Volt Board (Rectangular with two pins)
I have started including BCR Stickers so you can place them under the engine or tender, so you know which engines have BCRs in them. Instructions are also included.
Continental U.S. Shipping Only - Please ask any questions
I also have listed Battery Replacements for Proto-Sound 1 (QSI) and Proto-Sound 2.0 5-Volt Boards. These system use the 9-volt style rechargeable battery. Please take a look at that listing if looking for the 9-volt rechargeable battery style.
* I do make BCRs to replace the engines that MTH used actual AA Rechargeable batteries in - Please Contact me for these Custom BCRs*
