SkyRC RS16 1S charging

[Rumbl3r]

Any RS16 owners tried this and got it to work?

I've tried to use a 1S charging lead that has a balance plug on it. When I start the charge it says 'No Battery'. If I disconnect the balance plug it works fine. There's no option on the menu for Balance Charge with a 1S setting, so it's not that.

I know that some chargers can't work with the balance plug input on 1S, but thought the RS16 could?

TIA

I didn't realise you could get a 1s lead with a balance plug.

I never used the balance plug on the side of my rs16 charger for 1s lipos. I only connected the two 4mm plugs and set it to charge instead of balance and it worked fine.

I'd be surprised if any charger would need the balance plug input to charge a 1s lipo as there's only one cell so there's nothing to balance it with or multiple cells to monitor.

What 1 cell Lipo do you have that has a balance port on it?

1S packs don't have balance ports but the main outputs are also wired to the balance port on cell 1. I've attached a pic of how it looks (thanks to MC).

The theory is that the balance port reads the battery voltage whilst charging more accurately as it would on a 2S, and it's not confused by the current flowing down the main leads and the voltage drop across the main leads etc. You can see this if you put a DVM on the battery while charging and it will show different from that the charger is showing on it's display.

I'm aware of chargers that can do it this way, but don't know which. Anyone doing it and can you post which charger model you have?

TIA

I have 2 Skyrc chargers (rs16 and d100 V2) and both of them read cell error when using the balance port wile charging a 1 cell lipo.

The theory has been around for years, and I believe it's a sound theory, but not when implemented the way that everyone does it. Even on your pic, the balance wires are connected to the current carrying cables, and hence uses the current carrying connectors at the battery. For it to work, you need to connect as closely to the cell as possible, and make a different connection to the one carrying the current.

Good point! I hadn't noticed that the balance connection was at the charger end of the cable instead of the battery end. And I think you're right, most of the cables I've seen are made up are like the picture which won't provide the most accurate voltage reading.

Well so far I can see it won't work at all with the RS16 but hopefully Mark will tell us which charger he uses his lead with. I suspect the answer will be iCharger but he may have tried others.
