Treeman We have sold hundreds of the packs supplied by Air Wire, they have a low voltage cut off built into the pack. This will warn you that the cells are getting low and need to be disconnected. Lithum batteries are not to be stored long term at full voltage.

Greg Elmassian I use lifetime in terms of effective full charge-discharge cycles, and I'm happy with the 350-400 cycles that is often quoted. Since I normally only run down 50% or less then I usually get 800 "uses" and I am happy.

Michael Glavin This a thread might support a "poll" of some sort...

I'd like to see others results with battery powered trains and their life cycle with Lithium-Ion batteries...

Single series battery packs such as 4 cell 1S4P; 2200mAh capacity batteries are likely to live much longer in my experience as compared to an 8 cell 2S4P 4400mAh battery or any combination of cells combined in series-parallel configuration.

East Broad Top "Average" for me is 5 years of reliable service. I've got some that have lasted much longer (10+ years) and others which have for whatever reason stopped working properly after two or three. I try to make the packs removable in my installations whenever practical, which cuts down on the number of batteries I need to buy.

Later,

I have been happy with these folks for a long time. I started with their bike light /rechargeable flashlights for mine explorations, I could recharge in my truck away from home.
Then I used their NiMH tabbed batteries to make custom packs and then the Lithium packs after my others passed on....

Greg Elmassian Paul is not the first person to indicate that perhaps the Tenergy packs have changed in "lifespan", I've heard it from a number of our club members too.


I wish that packs came in clear shrink, so you could look inside and see the manufacturer of the batteries.

Paul Burch I have quit buying the 14.8v Tenergy batteries. I have had several of them fail in what I PERSONALLY think was a short life span. All my new ones are the 6800mah from Airwire. Time will tell.

NEVER run the batteries down until the train stops!!!! Contrary to the miss-information that many abide by, this is detrimental to the batteries life cycle.

What specific loco's? The LGB's are likely fine, yet USAT engines are hungry and will pull more current than the LGB's.

Best practice is to store your batteries partially charged, at STORAGE voltage which is typically 3.8V per cell as I recall.

Charge your batteries often with the appropriate current, do not wait until they are fully discharged, this is the established standard. Minimal discharges are best with a toping charge between use(s).

I recommend reviewing the link I provided above for up to date accurate/proven/knowledge on all things battery.

Thanks, Michael for the experience, I will observe these steps in the future.

Homo Habilis Just to add, all of my receivers are the G Scale Graphics RailBoss 4. One of its features is a low battery warning and cutoff system for Lithium batteries. To my recollection I've only had it activate for one engine so I don't think I've ever fully drained any of my battery packs.
