O.k. Just about have myself talked into buying a Bachmann 2-6-0 Mogul. I would like to convert it to battery power. I've read some of this board and have come to the conclusion that the RCS system should work for me. I'm a basic railroader with the potential to add sound later. From reading the RCS site it looks like I may need the TX-4 with Basic-2. Since I am electrically challenged the TEN-LOC installation kit looks like it might come in handy. Would I be correct? I also have a Li-Ion 18650 14.8V 6600 mAh Rechargeable Battery Pack with PCB Protection from all-battery.com on hand and would like to use it. Would this be a good battery for this application? I assume all this will go in the tender. Thanks for any help.
