Chargers explained

We offer two brands of Chargers.  MTO who assembles the battery packs and Cell-Con a leading manufacturer of medical grade chargers. Lithium battery chargers are selected based on voltage of your battery packs. These chargers will automatically start charging and when finished disconnect from charging.

As a safety tip never leave the charger plugged into your model engine and connected to the AC outlet longer than the charge cycle. You must Monitor the charger. When LED is green unplug charger cable from Loco charge jack and unplug AC cord  from AC  outlet.

How long will it take to Charge? Depending on which battery pack you selected, the charge time will vary from 1 hour to over 7 hours. These chargers use a 1 amp rating. That means if you select the Train-09, 3.5 amp battery, divide by 1 amp and it will take 3.5 hours to charge this pack.

Select the MTO lithium smart charger for battery packs with 1-4 cells. This smart charger will charge 1-4 cells or 3.7V-14.8V lithium battery packs. Plug in the AC power cord. The LED flashes red to green twice then goes off. Plug in your charge cable into the loco charge jack. When charging the LED is red. Turns green when finished.  Unplug both charge cable and AC cable when done.

Select the Cell-Con lithium smart charger for 5 cell or 18.5V lithium battery packs. Plug in the AC cord. The LED will be green. Plug your charge cable into the Loco and the LED changes to red during charging.  The LED changes to green when finished. Unplug both charge cable and AC cable when done.
