DCS Remote Max Voltage?

Life batteries are 6.6 volts..not far from 4 healthy alkalines. Both my remotes use eneloop rechargeables..i have installed a charging jack in each.

Daniel,

I would not use Lithium polymer batteries in a remote. These are made to run remote planes and such that need power. They should not be left unattended while charging. They have been known to catch fire while charging and burn when a remote plane chases. They are expensive, need special chargers and they don't last forever (3 to 5 years).

LiFepo4 much safer chemistry than LiPo. They are used in many of our RC transmitters. LiPo with internal PCB(protection circuit board aka BMS battery management system) are also used in transmitters but are usually certified by the manufactures. CQ is imperative.

Hey Joe,

I know very well the attributes of LiPo batteries, you are incorrect though in what they are made for. Your smart phone might have one, some small electronics use them as well.

I have drones and of course the only way to power four motors at once from a battery requires a LiPo battery with a high "c" rating.

I have arguably one of the most reliable LiPo chargers (IMAX B6) and I know not to leave them unattended while they charge. But I also use a low "c" rating battery in the drones remote with LCD screen, not for the batteries "c" rating but because it last longer and is easier than using a boat load of AA batteries.

With that said, that remote has an input range that was ok with being power by a LiPo Vs said boat load of AA batteries. (I forgot but I think it took 8)

I have a few 7.4v batteries that will work perfect for the DCS remote but I don't want to just connect it without knowing if the remote can run fine with the higher Voltage.

Thanks for the help though!

Toss in a few series diodes, you can drop the voltage to a safe level.

Something like this would work if you could get it to fit..has built in BMS

Still a lipo..caution,caution caution

I certainly hope my electronics don't have a LiPo battery in them. LiPo (Lithium Polymer) and LifePo4 (Lithium Iron Phosphate) are not the same and Li-ion isn't either. I would not use a LiPo in a remote. You should not confuse anyone reading this thread by using the wrong symbols for the batteries. They might actually try using them in their remote.

Hey Joe,

I am not at all confused my friend, why can't you use a LiPo battery in a remote? Is it not a power source? I will admit it's a volitle one if handled incorrectly but that is not what my post is about.

Let's do this, let's just say I want to power my remote with an un-named battery type that outputs 7.4v, can this be done to the DCS remote?

If you don't believe me about where these batteries are used then please read for yourself:

https://en.wikipedia.org/wiki/Lithium_polymer_battery

As you can see your electronics do indeed possibly have LiPo batteries in them.

They have been painted in a bad light because cheap Chinese processes have lead to serve injury and even death BUT in most cases when a good quality battery is purchased AND charged correctly, the batteries can be a great and light weight replacement to most of it's lithium-ion cousin.

Please don't tell me it can't be done, it literally is being done as we speak to fly the most expensive to the cheapest drones in the world (in terms of them being used in the remotes).

This topic is not about if LiPo technology will work, it will, the issue is that the cells will provide more voltage than the unit should have and I need to know what to do to handle that.

GRJ gave me an idea and I see others have done this for other applications, let me see if I can make it work.

Thanks!

All of my electronics have Lithium-Ion. 

The RC planes have Lithium-Polymer.

But, wanting to be on the cutting edge aside, what's the problem with NiMH? They are cheap, easily available, and have no safety issues I have 6 sets for 4 remotes.  I also often use the light in the remote.  Battery life isn't an issue--if BAT appears, I simply pop in another set from the 8-cell holder that sits atop my control panel.  Sometimes I grab another remote (if there's one not in use) and use that while popping batteries.

Robert,

I have no problem at all with NiMH rechargeable batteries, which I use in all of my remotes. However, LiON batteries can hold a charge quite a bit longer than can NiMHs or NiCads.

What's your point?
