Set name: 100Ah Bluetooth-Heating
Well since the "review checker" flagged my review as fake, I'm providing a picture of my setup. Not a fake review but a active 3Kwh per day generating solar array feeding 11Kwh of batteries. Using this to power my hobbies I have seen a $20 a month decrease in my utility bills and this is only spring, and not the summer solstice. I searched high and low for a smart BMS battery that has low temperature charge cutoff. As a bonus this even has a LCD display right on the unit. It all works as it should so far. I've only cycled this battery 2 full charge/discharge cycles and the BMS works as it should and is indicating a very balanced cell state of only .002v difference between cells when fully charged so the cells are well matched and the BMS does its job of balancing while charging too. I also purchased the big mama Temgot 300Ah and ran that through 4 full cycles. The cells aren't as well matched as the 100Ah, but they fall into balance about 5ah into discharge and have been staying relatively in balance. Presently I have discharged it 3Ah from full (297ah capacity) and the cells are within .010v which is about max that you would want of an imbalance for longevity. Discharging it more to about 295 Ah capacity, I see all the cells fall into .006v which is quite acceptable and does follow this when static, but when under heavy discharge I see a difference of up to .01v between cells (150A load) The balancing feature seems to be better implemented on the 100Ah than the 300AH battery but during charging I have seen the active balancing enabled through the app indicating it is balancing, but from what I see it is only in the ballpark of .01v The battery is relatively new so we'll see how it handles after some more charge / discharge cycles. Keep in mind, other lithium cells do not even have the ability for you to see if there is a imbalance between cells, so having this ability really gives some insight to their longevity. I have tested both Temgot batteries for capacity and accuracy of the built in BMS touchscreen display and I am impressed with my measurements at room temperature indicate that they are within 2Ah of their rated specification. My measurements indicate that I had achieved the manufacturer rated usable capacity with a shutoff at 10.8vdc and using a rated LiFePO4 14.6vdc 20A charger for the 100Ah battery and a 40A charger for the 300A battery. Obviously if the battery sits unused for a period of time, you will not be able to achieve the rated output unless it was just freshly charged to full capacity. The batteries arrived with about 69-71% charge capacity. Charging to full indicated that they were closer to only 50% capacity. The battery casing is painted white/orange which can easily get scuffed to reveal a black plastic under the paint. The construction of the two batteries I purchased are flawless but I quickly scuffed the paint with testing/use. So far the only con I can hit these batteries on is that the BMS capacity monitor cannot really see any load smaller than 800ma or less. It merely does not trigger the BMS into thinking there is a load that needs to be monitored so the "odometer" capacity gauge is not engaged to count down indicating power is being consumed. Charging the battery is about the same with lower currents not indicating it is charging. This is demonstrated with a 3 amp constant charger that I have that shows a red light if there is any charging active. The BMS shows 0 current, no protection active, and the charger will have a red charge light for another 10-15 minutes before it falls to a dormant green light status indicating that charging is truly completed. The purpose use of these batteries is for off grid/ portable power applications. The bluetooth app is kinda clunky and I do not recommend setting a password if the BMS allows it as it can make things worse when monitoring multiple cells and I have yet to find a way to disable the password once it has been invoked as even putting a null 000000 does not disable it and needs six 0's entered to gain access to the BMS. So far I would buy again and I have as I own 5 batteries now all from Temgot.

My first ever lithium battery, it’s a group 31 size but when I ordered it I thought I was getting the group 24 size which is ok by me, it’s a little bigger than I wanted but made due by getting another battery tray. Functional for what I need it for (Humminbird graphs) I charged it fully and have been out numerous times, I’m guessing 7 times now, 6-7 hours each time and the battery is still about 50%. I like how it’s Bluetooth, has its own LCD display built right into the top of the battery which allows me to view the information of battery life, charge remaining, hours till fully charged, individual cell voltage etc. Charges just fine with my NOCO 10a 4 bank charger. I especially like the weight less than 30lbs.

Love how simple it is. I don't know the technical names of the display, but it's easy to read and not have to hook up to the multimeter. Not sure if I'm supposed to put the red/black caps back on though. Used 100Ah to charge Ecoflow power stations/solar generators (without waiting for the sun to come out). This set up is WAY cheaper than Ecoflow prices and apparently, it has a lot less parasitic power drains. Here's my set up: - Hooked up battery to cig lighter plug - to plug in the power stations/solar generators. - Battery is plugged into a smart car battery charger and into a wall electrical outlet - to keep it charged. Benefits: - All 3 pieces are less than HALF the price of an expansion battery. - This set up is twice as much watt hours (12.8 x 100 = 1280 wh) than an expansion battery. - The 100 Ah is about 25 pounds making it easy to move. I would prefer to have 200 Ah but prefer the low weight of the 100Ah. - I read LifePO4 batteries do NOT have same explosive properties as other batteries. Opportunities: - I would LOVE for Temgot to have a fire bag to cover the battery. The one I bought covers the display... and to me, that's one of the features I LOVE about the battery. - I am confused why some info says Temgot and other times it says, Temgo (without the T). I got worried thinking that the Temgo is a fake site. It seems legit... but confusing as to why it is that way. Thumbs up! Great product.

Shipping was fast, batteries are exactly what I need for long camping trips, weight of them is much lighter then my old lead acid ones, performance so far is great and installing them was easy took 5 min

UPDATE 6-13-24: After multiple firmware updates the app is now connecting easily and responds quickly to any changes. Have charged and discharged multiple times with no problems. Battery is high quality and functions fine on its own. Really nice color touchscreen on top of case. And a great value too. Except for the app I would give it 5 stars easily. The problem is you can only get the app to connect about 1 in 50 tries. Frustrating as that was one of the key features I liked. There has been 2 software updates in the app in the last week. Maybe they will eventually get it fixed.

First off, lifepo4 batteries are the way to go, lighter than deep cycle batteries by far AND the depth of discharge for a lifepo4 is 100% ONLY negative to a lifepo4 battery is charging below freezing will damage it. With tge ability to see the state of charge, amount of wattage being drawn in real time. Also the ability to bluetooth and see the info, or on this battery that has a display screen. I purchased one of these Temgot batteries for my trolling motor, I was so impressed that I ordered another one to extend the run time of my solar power stations.

Even with a surprising lack of overall reviews, I went ahead and (eventually) bought five of these Temgot 12v-100ah LiFePo4 batteries. I'm impressed with the unique onboard battery display, BMS and blue-tooth BMS connectivity. I found this battery to be one of few that offered a safe low-temperature 32-degree charging cutoff and impressive charge-cycles for the price-point (while I didn't want onboard battery-heater option). So far these batteries have passed all challenges for my solar RV. Several play-store BMS apps (besides the recommended app) function fine with the battery's BMS. Only been a couple months now, but impressed so far! Will likely get a few more!
