I'll check on charger calibration options today.

I'm sure the meter is good because the POS USB charger (which apparently isn't too bad beside the literal hours it takes to charge) is charging to 4.32/4.33V according to the meter. I'll still check meter when the tester arrives Tuesday.
Voodoo, the reading on the charger when finished charging was 4.31V, while meter reading was 4.27 on all four batteries.

I would not worry if the LiHV are a few hundreds of a volt off.
It is good to have references voltage to calibrate test equipments. Unfortunately, calibrating most charger is a impossible. • Posts: 863 Threads: 43 Likes Received: 286 in 202 posts Likes Given: 12 Joined: Nov 2018 Reputation: 5 Yeah, I think I'll raise it to 4.35V and see what happens.

• Posts: 863 Threads: 43 Likes Received: 286 in 202 posts Likes Given: 12 Joined: Nov 2018 Reputation: 5 I changed the end voltage to 4.35V and put the four batteries that only charged to 4.27V back on the parallel charger. Ten or fifteen minutes later the charger finished. The voltage now reads 4.31V across all of them.
I say close enough. What about you?
As a side note I've been able to see that this charger can do a whole lot.

Can your charger meter voltage? Plug a pack and see what is the voltage on the charger. If it reads 4.35V but you DMM reads 4.31V, then one of the device is not calibrated. If they both say 4.31V, then maybe your lipos are not holding a charge. If the meter on the charger reads 4.35V and your DMM reads 4.31V, then again one of the device is off. • Posts: 863 Threads: 43 Likes Received: 286 in 202 posts Likes Given: 12 Joined: Nov 2018 Reputation: 5 So the Kkmoon arrived. How long do I have to charge it for it to do anything? Been plugged in for about two hours.
I push the button, nothing. I hold the button down, nothing. I hold the button for at least 30 seconds, nothing. Is the button just for show or what, hehe?
The red charging LED is on, and the four others briefly light when I plug it in. Charger is the recommended 5V. I'm assuming the light shuts off when fully charged, but does it have to be full to operate?
Am I doing something wrong?

I charged mine for about 10 minutes and it is back and working. Yellow led indicate charging. Hold down for 2-3 seconds and it turns on. The red light come on over the different voltage at the lower half. Pushing buttons changes the voltage. ![[Image: SjyHw0pl.jpg]](https://i.imgur.com/SjyHw0pl.jpg) I am not sure why yours is not turning on. Maybe DOA. • Posts: 863 Threads: 43 Likes Received: 286 in 202 posts Likes Given: 12 Joined: Nov 2018 Reputation: 5 Yeah, still nothing. Looks to be dead. I guess I'll start the return process in the morning. I'm on quite a run. Counting this issue I'll have three defective items I'm dealing with right now....

That is really not a good run. I wonder how the reference voltage went bad. It is tested at the factory. • Posts: 863 Threads: 43 Likes Received: 286 in 202 posts Likes Given: 12 Joined: Nov 2018 Reputation: 5 There is another on on the way. Hopefully I have better results with the new one.
The first one didn't have a yellow light. It was red. Dated 2018 so age doesn't seem like an issue.
