  • Impressed so far!
Size: 12V100Ah-Smart Version
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! ... show more

  • Great battery. Used it 30+ times already with no issues. LCD screen is useful
Size: 12V100Ah-Smart Version
Still no issues after many uses. The LCD screen is very useful to determine battery life. Lasts so much longer than my lead battery for my trolling motor. I get an easy 6-9 hours with my 40 lb thrust trolling motor.

  • Good Battery Terrible App
Size: 12V100Ah-Smart Version
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. ... show more

  • Good review after about 3 weeks of use
Size: 12V100Ah-Smart Version
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. ... show more

  • These batteries are Awesome
Size: 12V 100AH-Heating
Like most I was nervous about purchasing an Amazon Chinese made product. I read the reviews which were extremely positive After installing them and putting them to use in a two day bass tournament I am extremely impressed. After fishing all day and covering a ton of water the batteries were only down to 77%. The phone app has worked flawlessly and the touchscreen is awesome. ... show more

  • Works very well

I bought this to charge a charge my BLUETTI solar generators when I don’t have good solar conditions. I hook the battery to my 300w Bestek inverter and then plug in my 200w AC brick to charge either my BLUETTI AC180 or EB70S. Works great for charging at night if needed. I love the display so I can track the battery charge level and how the cells are performing. ... show more

  • Bluetooth and LCD displays are awesome for tracking battery data!

Both of the batteries arrived in excellent condition, and the LCD displays were excellent, both in the visual data displayed. After installation in my truck camper, I can access the battery data with the app, from inside my camper, and also from inside my home.
