LiTime 500A Battery Monitor with M8 Shunt, 8V-120V, LCD Display, for RV

works perfectly

Just installed this yesterday and haven't had time to review all the functions, but screen is easy to read, displays volts, amps and watts clearly and percentage of remaining battery power in our lithium batteries, seems to be well built and so far I've been impressed with its functionality and quality. Hooks up easily and shows all the information I think I need to monitor our battery life. Pretty impressed so far. Will review again after I've spent more time using it in our camper.

UPDATE 2: manufacturer reached out and replaced cable way after any warranty would be in effect. Kudos to them. Updating to 4 stars. UPDATE: two months in it started giving weird signals. Took me a minute to realize the flimsy wire harness had finally broken. Not durable at all for a $90 piece of electronics. I do not recommend Old review:Gives you essential battery monitoring details. Easy to install. Longevity vs the Victron probably depends on how well you secure it and what kind of driving/boating you do. Screen light shuts off when needed.

Purchased this product to monitor my LiTime 200aH battery ~2 years ago. This monitor has worked great up until about 2 weeks ago when one of the wires that plugs into the monitor broke. I emailed LiTime, they asked me to send a picture of the broken wire, and then immediately sent out the replacement part to get me up and running again. Not only that, but it arrived to my rural address in only 2 days. HIGHLY impressed with their willingness to even warranty the part, being that it's just under 2 years old... but also the ease in which the communication happened. It wasn't jumping through a million hoops like with other companies, and then waiting an ungodly amount of time to process the request. From initial email to part delivery was about 4 days (and prob would of been 3 if I'd replied to initial email quicker). HUGE thank you to Bella (the CS person I worked with) for making everything so simple and smooth. This type of customer service weighs heavily on my future product decisions and is greatly appreciated. BTW, I later found out that it's just a standard "5 pin JST XH" cable, as I saw a few other reviews mentioning the wires breaking from the connector. Less than $10 for a ~5 pack here on Amazon.

Gets the job done. I had upgraded my lead acid batteries on my RV to a LiTime LIPO 230 ah battery. I wanted to add a shunt and add the LiTime Shunt. Not too difficult to install. I cut a hole in my RV panel to install and looks great. My only wish would have been that it had Bluetooth connectivity but I knew when I purchased it didn't have it. I added a Victron Shunt later with Bluetooth capability and they work together fine. And they both read the same so this tells me the LiTime shunt works great. If you don't care about bluetooth it works great.

I've used other monitors, but I like the interface Li Time has and the percentage capacity. During setup I did find one issue in the manual I received in the box. The manual stated to set the "Full V" parameter to the batteries "resting voltage". I have a 12.8 Li Time 230Ah Lithium battery. Typical "resting voltage" is 13.3V. The problem is that the monitor uses the charging voltage to set the capacity to 100%. My experience was the monitor showed 100% capacity prematurely as the charge voltage reached 13.3V. I contacted Li Time and they were very quick to correspond with me and they updated their manual and sent me a new version. The new version says to set "Full V" to the batteries (system) charge voltage. For a 12.8V Battery that value is 14.2V. The Lithium charge can charge as high as 14.6V when the battery is at/near full charge. I did set my value to 14.6 before corresponding with Li Time and the charging/discharging tests worked fine. I will probably set my controller now to 14.2 and see if it makes any difference (but I think either value will work) I've corresponded by email with Li Time now 2-3 times and every time they are very prompt and super helpful. It has been a great experience for me. n updated manual was

October 2024: Bought this to monitor new Litime batteries. Handles up to 500 amps. Wish it came with a mounting bracket. Its meant to fit in a cabinet cutout, I mounted it to the wall using Command strips. Helpful knowledge about the background light: a. Background light is off when no current is flowing to or from the batteries b. Background light flashes softly when batteries are charging. c. Background light stays on when batteries are draining. October 2025 update Accurate readings and works well but temporarily cuts power off at 50% load (250 amps).

The directions say to completely discharge the battery and then hold the down arrow. Well, after the bms shuts off the battery there is no power to run the monitor. Charging for a minute and then letting the battery rest, seemed like the thing to do. When holding down the arrow button, there in no response to let you know it has "learned" the discharged state. Same for setting the fully charged state. It is easy to accidentally hold the up arrow instead of the light button when it is dark and you want to turn on the light (it is installed in my travel trailer). Holding these buttons does not change the zero and full voltage numbers in the menu, so what does it really do? The monitor seemed to work after I set the discharge point, but then it acted odd and did not show a reduction in battery capacity after putting a large load on it for 30 minutes. A 100 amp load should have reduced a 200 AH battery to 75 percent, yet it still said 100 percent and 200 AH on the display. I emailed the company regarding this issue, as it was near the 30 day return limit on amazon, and they never responded. I wish I had gone with a victron monitor. The litime battery is recommended by a popular youtuber who has opened a number of them and the price is much better than some of the others, but I can't recommend the other devices they sell and am questioning the quality of the battery since I don't have a reliable monitor for it.

It's a basic green back light battery monitor, we can expect calibrated results from this. A bit over priced in India. Didn't find much of an option so purchased this.
