Anyone wire up a LC loco to run from a battery?

Do a search, plenty of battery options available.  G

Since the LC and LC+ stuff will run on DC, it's probably simple enough to use a Lithium battery pack in a trailing boxcar and just tap into the track pickups of the locomotive.  If you're going exclusive battery power, I'd remove the pickups.

I'd be looking at the 12 to 18 volt range for the battery pack voltage and as much capacity as will fit into your battery car.  A good place to look is model airplane sites, they have the battery packs and the chargers as well.

A good plan would be to have a couple of battery packs so you could be charging one and running with the other one.

Here's a site with a nice assortment of 14.4 volt packs, about ideal for LC and LC+ stuff.

Here's an appropriate charger for that pack.

BTW Brian, I've seen some of your work, your expertise amazes me, and I can excuse the lack of knowledge in on minor area.

That will be somewhat of a SWAG.  I'd start by running the engine around and measuring the current draw.

Let's say that in typical operation, you were drawing round 1 amp, I'm assuming you might be using the smoke unit.   For each hours running, that would be 1000 ma/hr of battery capacity.  If you pick this 2400 ma/hr battery pack, you'd get around two hours of running.  The nice thing about Li Po batteries is they keep their voltage up for most of the discharge cycle, so you can use most of the battery energy.

Obviously, the 1A is just an example, I've never measured the LC or LC+ stuff to see what it actually draws.

For what it is worth...Trying to learn a little about this electricity thing yesterday ... I have the LC+ GP7 (two motors), and LC+ Mikado (one motor), and when I run both the HF clamp-around ammeter says about 1.8 to 2 amps at 18 volts (Z1000) on the main bus connection when both are running 1/3 speed and both smoke units are engaged, each pulling a half dozen cars.  If I crank up the speed to almost flying speed I can get 2 amps on the meter.

Also have the LC Pennsylvania Flyer starter steamer, so I jusr ran downstairs for a quick measurement, When I run it alone it registers 0.8 to 1.0 on the ammeter as it runs around the track puffing away and pulling a half dozen decently weighted cars.  If my measurement is anywhere near accurate, John's guess was a good one

Not such how accurate this inexpensive meter is but I guess I was surprised at how little current, especially the LC+ seemed to pull.

Disconnect the wiring from the DC motor and run 2 wires from the motor to a battery, with an on/off switch in one of the wires.  Shouldn't be hard to stop with your hand if you can catch up to it.

I would get a 9.6v NiMh battery pack, $20 from any RC shop or here:

Mah isn't that important if all you're doing is cleaning track and not running it around more than an hour or so, don't even need track power turned on.

You could even gut the engine, just leaving the DC motor if all you need is a track cleaning car.

Of course...if you went BPRC you wouldn't need to clean the track at all

Either am I, I meant search this site.  There are plenty of post of converting TRAINS to battery.  Bob just did this and he posted above.  No need for google yet.  G

Bob, I don't know why you'd want to connect directly to the battery and lose all the benefits of the remote control, you'll have to explain that one.  It's just as easy to simply connect the battery pack directly to the track feed and have the full functionality of the LC or LC+ locomotive.

Again, I'd opt for the higher voltage pack and run the electronics package the way it was designed, simple and effective.  In one boxcar, you can haul enough batteries to run all day, so that's not really an issue.

John, I thought he had a clunker that didn't work or worked poorly.  He could always do what I suggested and put the guts in another engine, or take a clunker and do what I suggested.

Bottom line is there's a number of ways to run a battery-powered engine around the layout.

Bob, from the first post.

It occurred to me it would be advantageous to have a battery powered Lionchief loco to pull the track cleaner when things get bad.

I took that to mean he wanted to run an intact LC locomotive with remote control.

Also from the first post:

I have a LC 0-8-0 from a starter set I'm not really doing anything with.

I'm only guessing at what he really wants to do with what he has and only throwing out suggestions.

You're right Bob, I assumed the same thing.  The difference is, I assumed that it was a working locomotive, but he wasn't using it.

We'll have to wait for Brian to tell us the real scoop.

Hi Brian

Perhaps you could do as I do, and find a connector that's readily available in your area, cut off whatever connectors stuff arrives with and replace them with your chosen 'standard'?  I'm building up my own cheap radio control for locos using R/C car electronic speed controllers and simple 2-channel radio control transmitters - the bulk of the receiver and transmitter is no problem in O-scale.

For robustness, NiMH batteries are hard to beat.  I know LiPos are far more compact, but I have had no end of trouble with LiPos failing after only a couple of cycles so now I reduce my stress levels by using Energizer AA's in four-cell holders, wired in series to get 9.6V.  It gives acceptable run-time (Energizer AA is 2.3Ah) and top speed.

Since the battery and charger are from the same folks, I'd simply ask them which connector is compatible with the battery pack you pick.  I'm sure there is one for the charger that will charge their own battery pack.

Let's say you picked this 2400 MAH pack, it's a decent capacity and fairly cheap.  It's charging plug is described...   1.5" wire with 5 pin Female JST plug

I suspect one of the choices for the charger is compatible with that plug.  Note that you can't just charge the whole pack, multi-cell lithium packs charge with monitoring of the individual cells.  So, it's is important to match the charger connection to the battery charge port.

I'm not sure why Paul has so much trouble with LiPo batteries, my brother is an avid model airplane guy, and he uses LiPo exclusively for all his stuff now.  He gets many cycles from those packs.  One advantage with the LiPo solution is you can go for a larger battery pack and get hours of running on a single charge, so you'd be able to have an entire session with a single battery and no breaks for charging.

If you are discharging at a 1 amp rate, which is roughly what we are talking about, the AH rating of a primary AA alkaline cell falls to around 1 AH.  You'd want at least eight of them to bring the voltage up to around 12 volts for your configuration.  Also, fairly early in the discharge cycle, the voltage falls off significantly, further impacting performance.  You'd get maybe an hour of running, if that, and you'd be buying new batteries regularly.  That will get very expensive fast.

For any doubting Thomas in the crowd, here's the PowerStream Discharge Tests for various Alkaline and NiMh AA Batteries.

You could go with something like a bunch of NiMh AA rechargable batteries in holders, those would  be a lot more cost effective than using primary batteries.  They also stand up to higher current discharge rates better than Alkaline batteries.  Alkaline cells are best suited for low discharge rates.

Hi GunnerJohn

Thanks for the link to the battery discharge tests, very informative and the charts back up what I had already discovered working empirically, that NiMH batteries hang in there for longer than alkaline cells.  Because I am working with dead-rail more-or-less in isolation here, it is pleasing to see that you suggested exactly what I did....means I'm probably on the right track :-)  All the other deadrail guys I communicate with are using LiPo's due to space issues in their Ho and On30 engines.

I probably had issues with LiPo's failing because out of ignorance I was buying low-quality batteries.  However, given that I have ample volume inside an O-scale locomotive so that space is not an issue, plus the fact that so far my Energizer NiMH's have been indestructable, I quickly arrived at the conclusion that in my situation LiPo's are just an unnecessary complication.

By the way, if it is of any use to anyone, I am using a HobbyKing HKC6 charger.  I love it, because it is clever enough to use pulsed voltage and current to recondition over-discharged batteries and revive them to not far short of their original capacity.  It also automatically senses the total voltage of the bank of cells in series and charges the lot, so I can charge any set-up without having to remove them from the engine.

I will say that the NiMh batteries will probably be easier to deal with, they're much less demanding of proper charging techniques.  I'm kinda' conditioned to thinking LiPo as my brother is a huge fan, but flying anything heaver than necessary limits the other payload you can take up, cameras, and other fun stuff for bombing runs.
