New item,it is better than HA02 Battery equalizer
It does have a pitch as someone mentioned which is how I figured out initially the one failed so there’s no lights or anything which only would draw additional power so My little Whataburger suck at murder is about the best way you can make sure everything’s consistently working you can pretty much just walk into the room see the batteries are doing. Everybody complains about China but here we are electing Biden opening up the borders to illegals And have had shootings every day since month after he took office!
I’ll update the update the company doesn’t respond as never responded but after swapping defective one haven’t had any issues with my 2 units. I just added another 48v bank so buying a 3rd one. Lol the Wires getting annoying but working on better layout design I hope for designated room.
It might be over kill but I use 1 per 4x batteries since only good for 10amps and I’m fully off grid on flooded lead acid so I just want everything optimized. I’m using heavy duty commercial 8DFT from ORiley’s so not a deep cycle but they still test good after 1 year. I rarely bite more then 30%DOD which is becoming easier to manage with each additional bank. I’m probably going to start buying the group 31 Deep cycle and have a hybrid combination of heavy duty start and deep cycle. Weight and transportation is really main issue lol otherwise I’d be buying Rolls lol.
UPDATE – SO COMPANY DOESN’T ANSWER EMAILS OR RESPOND & CHINA PHONE NUMBER -So I received my replacement and can explain do you y’all how to test using a voltmeter either with homes or the alarm setting.
If your ohmmeter has the alarm function put in that and if you touch the negative and positive and the alarm goes off it’s a close circuit in the device is bad I waited till I got my replacement to test my one that went bad and the one that works along with the replacement. If you get any kind of homes that are even a crossed off 4 I’m setting it’s bad there should not Be a constant resistance or an alarm.
be a constant resistance or an alarm.
Tossup on what you get these are made in China I went to the website all silly typos in English. Can’t get technical support. I’ve had one for two months and one that I just got on the last two weeks they seem to do their job but they run hot to touch seems like they are under sized on wire
