Hota D6+ on its way out?

[Hector_Fisher]

I thought I had a lipo problem:

Turns out, I think, it was a charger problem.

I've tried swapping out balance port connectors. Reconnected may times. Verified the numbers from the b6ac with a multimeter. Anything else I can try to diagnose a failing hota charger channel? Sucks to think of any damage I might have done to my other lipos when this thing was on its way out. At least it's just channel 1, I still have the second channel to use.

Worth a shot.

Worth a shot.

Went back to try this and the channel was reading correctly. It seems the inconsistency is what really worries me.

Like earlier today, for example. It was reading balanced at storage charge when i plugged it in, and then a while into the charge it reads this

Are you using DC or AC and have you tried the opposite?

 

[Hector_Fisher]

Don't have a power supply, so just AC.

 

[RCSteve]

Plug it into your car battery. Power supplies that are going out make electronics do funny thing, just to rule it out.

 

[Hector_Fisher]

Thanks good idea. Forgot I've seen plenty of videos with people using a car battery as the DC input for a charger and the car battery on trickle charge or something.

You could also just use a different lipo as the DC power supply.

I think you can calibrate it? Some of those HOTA based ones you can anyway.

I don't think it's a matter of calibration. The voltage "wanders". Regardless of calibration, I would still worry that while charging later on the voltage could wander and kill another lipo.

You can. The problem with calibrating a charger for normal hobby folks is we don't have anything to accurately calibrate them with. You need a lab grade voltage source, especially down to the thousandth decimal, which HOTA's display.

Stupid question do you have the balance lead plugged directly into the charger or is it plugged into one of those balance boards like this? Try plugging the battery directly into the charger.

I’ve had that happen multiple times. That’s why I don’t use them anymore unless absolutely necessary.

Yes I've tried both ways.

Exactly why I asked, I've had my fair share of those things die on me too. I don't even think I have any of those left anymore.

Okay just wondering.
