The charger DC adapter producing 12.2 volts instead of 12.0 exactly is not warranty. There are many reasons why all AC/DC adapters produce voltage which is a few decimal points (sometimes entire whole numbers) from the output specification. This has to do with load, input voltage, and more...

ok why have i 4 death batts?i just took one out of jd.death.

No offence but if you have 4 batteries which have become faulty and very few, if anyone else, has issues there can only be one real common factor.

What you have described, as far as voltages is concerned is correct and acceptable.

Damaged batteries should never be used. A damaged lipo battery is extremely dangerous. I cannot believe any factory would miss a damaged battery during it's quality checks, let alone send four out to the same person.

Review all instructions and advice on the safe handling and charging of batteries to avoid any future issues.

the batt was allreddy in the jd.and there are many other problems normal factory, chould see.this started some week ago.you cant convince me 4 times in a , chort period is bad use or whatever.i use my robots 2 times a week. also you cant messure the balancer.i have two more jd's,am sure am gonna find, same batt like the others.i always looked very carefull while playing and charging. today a balancer can be good 1 hour later bad.

dj you talk about the charger alone,not the batts 4 times is not normal. nobody opens up his jd averytime to check the batt. am sorry to say ,if this is not warrenty,am done with ez robots. just let me know.

i checked all my robots and found 2 more bad batts.1 in jd 1 in roli.thats 6 bad batts one bad charger.i didn disable the voltage on the, web page 6.6 .i upload video tomorow.this is hell

this is disrespectfull,not good.the chargers overcharge more then 10.10 volt the other goes from 9.00 volt to 7.00 volt it goes up and down. thats what kill the batts.

Hello @Nomad it seems you have a number of problems here, in order to make sense of everything we are going to have to take it one step at a time.

1. With the multimeter you are using, does it have a fresh battery? I have seen readings that have greatly flucuated in these type of meters due to a low battery.

2. How does the AC power adapter voltage in question compare to the other ones you own? This will verify that your voltmeter is ok.

3. If there is a single AC adapter that is not like the others (has a low voltage output), did you use this adapter (with the blue charger) on all your robots?

4. Was the AC adapter in question new? Does the wiring look pinched or squished anywhere?

If there indeed is a faulty AC adapter we will have to look further into it.

The battery you showed in the video looks like it was completely depleted and then charged again. This will puff a LiPo battery up. A battery cannot ship this way as it is against shipping restrictions.

Thanks for your patience Nomad, please answer these questions and we will work with you to resolve your issue.

yes the digital meter has a frech batt

selftest the meter shows 0.00 ohm so ok

the adaptor chould gif 12 volt but it gifs 10 a 11 volt

the other gifs 9.5 volt to 7.5 volt goes up and down.

averything looked new in box adaptors

i cant know what i cant see

the last 3 bad batt came out of roli and six jd .,they just begun to puff

sofar i know the adaptors are not good.and

previous 2 balancers where also not good and got warrenty.

am not happy with this cause its not the first time

i mean when i say if this is not warrenty ,then its goodby
