Review: Great price and battery - I've had it for a short time and and impressed so far. I have not used it for on my trolling motor, which is one of the main reasons thatt I bought it for, but have done a multitude of tests. Came with about 70% charged in a well packaged sturdy box. Discharged to about 10% and then re-charged to 100%. It recharged to about 5AH over the rated battery amount. I hooked up a 500w power inverter to it and ran multiple 115vac items and it performed well. I ended up running the battery down to about 50% and let it sit for a few days and the voltage remained steady. Recharged to 100% again and it has been sitting for about 3 weeks without any voltage drop. I also hooked up a power inverter and ran a 12vdc portable freezer/refrigerator with a compressor that was set at 5F. The amp draw varied during the frig running due to the compressor kicking on and off. Checked the temperature of the frig/freezer many times and it ran flawlessly. After 23.5 hours the battery was at 17% and I turned everything off at that point. Recharged overnight and it recharged fully to 100% and 50AH. I cannot rate the longevity as it is pretty new. I am a looking forward to using it with my 30lb thrust trolling motor. I highly recommend the DJLBERMPW 12V 50Ah Lithium Battery. UPDATE TO REVIEW 9/14/24 I have the battery installed in an enclosed ammo box that also has a PWM installed in the same box and the PWM puts off quite a bit of heat. The faster that I run my trolling motor the more heat that the PWM puts out. I ran the trolling at various speeds of 30% to 100% power without any problems and took the battery down to between 50% and 30% on those days without any problems. Then one day we wanted to get back to our dock in a hurry. At that point the battery was at around 75% and we ran the trolling motor wide open to get back. After running the motor at 100% speed for about 45 minutes everything went dead. My conclusion is that the battery BMS had shut down the battery due to the excessive heat in the battery box. I arrived at that conclusion due to the fact the once we got back to the dock the battery worked fine after it was cooled down some. I verified that conclusion the following day by running at 100% trolling motor speed for over 1.5 hours with the lid to the ammo box propped open with a stick without any problems. 1.) The BMS worked as it is supposed to and protected the battery. 2.) The shut down was not due to the battery being faulty. It was due to the battery working as it should. I have already ordered a 12v fan to install in the box and do not anticipate any other problems once the fan is installed. I recommend this battery 100%.
Review: Excellent at this price point - I bought this battery to expand the house battery bank and because it was so inexpensive, I had to see how well it was built. At this price I cannot even touch raw cells at this price. So, I was very curious to see what corners were cut to bring down the cost. I tested the battery with a .2c discharge for 5 hours and to my delight it came in at 103.4 ah Not a big surprise as the cells are 102 ah cells. Short circuit protection, over current and overcharge protection all work as they should. The BMS is good quality and works as it should. The terminal connections are 2, 8 awg silicone wires and are adequate for a sustained 100-amp draw. The cells are brand new Gotion manufactured this year. The cells are matched and balance well at the top of the charge. The build quality is very good all laser welds on the busbars. The screw connections at the bms and balance leads all covered in silicone to prevent them from shorting or backing out. The battery case is well sealed in fact it was a nightmare to get it open which is a good thing. At this price point you can not build a battery for less. At roughly 60 dollars a cell the is the best built battery I have seen at this price point. I tear down a lot of batteries as it is a hobby of mine and this is one of the best built, I have seen for this price. The price of Lifepo4 batteries has really come down in comparison to usable amp hours they are now less expensive than lead acid batteries. The quality is really starting to come up on them as well. This battery is proof of this. Its well-built, safe with a quality bms and new quality cells. I am happy to say no corners were cut with this battery. I would recommend this battery to anyone in the market for a good lifepo4 battery.
