Thread: Anyone have a Turnigy 6-80w charger for Lithium batteries

Yep I've got one. Had it for a couple of years and it works well. I use a home brew battery pack (two of them actually) made up of 4 10AH LiFePo4 cells in series. I use the balance connector and don't bother with temp sensing.
It's a bit slow being limited to 80W but it does do the job.
I use the batteries for Amateur radio where current drain can be pretty high - up to around 30A. The charger can't keep up with charging a battery while I'm using the other in a high duty cycle environment - up to 80% transmit (~30A) 20% receive (~1A). Makes me take a bit of a break every now and the I suppose. I haven't looked too hard into either building or buying a higher current charger but I'll probably start looking in earnest when the AGM's in the camper kark it.

To find out exactly how it works I downloaded the manual and had a good read and a play. Manual is at https://hobbyking.com/media/file/347886993X90943X41.pdf

So the Turnigy is designed for individual cells and can balance them, rather than a LIFEPO4 car type battery with its own balance circuit.
So How would it go being set to 3.3x4 =13.2 volts with one output wire? Or would I have to DIY and buy 4 individual cells?

With further research there is a 4S 16000Mah pack available in a Lipoly which will plug straight into the charger and the charger will balance the cells.

That setup look to be good to use my LEDs in the camper when disconnected from the car and totals only $110 or so for both.

I found some cheap BMS boards from China, I've got similar plans to you. Not actually tried them yet though, been too busy. I had a pack of 26650 cells in the cupboard from a forgotten project, and 8 still worked. Had someone spot weld them together into a 4S 2P set. Once a 4S pack is fitted with a BMS you should be able to charge it from anything within reasonable voltage limits:

Yes, I use the small Turnigy 80 watt unit for my 3S batteries on my small drone, but it's too small to charge the 6S, 10,000mAH batteries in a decent timeframe on my Hex, so have a much bigger puppy for that.

They don't need the balance plug from the battery to work, but makes them live longer if you go down that path.

I've used the 80 watt unit to charge my motorbike battery once when I wanted to trickle charge it.
