Impressive power - using in grandsons battery Jeep that had FLA and of course that died a while back. Tried the Milwaukee M18 converter and no go - can't put enough current out... Jeep is true 4WD with motors on each of the 4 wheels. I thought it'd be good to have a fuse in line (wasn't one on the FLA) - so I added it... Blew the 15A fuse immediately. Put a 25A fuse in and he rode it for about 5min, blew that one. Put a 30A fuse in - lasted about 20min.... and it blew... was VERY hot. So now going to go without a fuse for while to see how it works....(remember, the FLA did not have a fuse) Bottom line is - this battery is very impressive that it obviously can put out in excess of 30A - I haven't measured the voltage to see how it has dropped, but betting that we'll see more capacity than spec'd. I will also do a load test to see the voltage drop under load.

Have a Cyberpower UPS with Seal batteries. Got an error code E02 which means filed to charge. Could be unit or batteries. I got these Lithium 10ah. Comparison. Seal bats were 12.9v at 9ah, and Lithin in 12.8v at 10ah. Once I tested UPS the old batteres were in fact no charging. Replaced with these higher end batteries and it was a flawless install. Perfect size and easy fit. The batteries were 99% charged and y the time I was done it went to 100%. I had orginally 396 minutes run time with a 1.5% load. Main used for my main finber and satelite internet. When I got this installed, it went to 420 minutes of run time. I have another unit and tested with that 1.5% load. Unplugged the unit and waited 10 minutes and it dropped from 396 to 379 minutes. On the new setup same test went from 420 to 416 in 10 minutes. WOW! In the end the new battereies worked perfect and I should do all mine UPS units this way, something to think about. I could have replaced the unit at $259 or get these at $63. I have been sold on the idea many years ago to use a UPS on everything you need power to when you have an outtage or like me or live in a rural area with contant drops or spikes, then a UPS is a must. Hope this helps some of you. I will start to place my batteries now before the actual units go back. And the fact they hodl a better charge is a win! Oh and old batteries will recharge at 2.7 amp max where these new one will 5am max. So faster recharge time when they do drain.

Love them long life batteries

So happy I replaced my old 12V 9 amp hr lead acid battery in my Silent Partner tennis machine for this lithium phosphate battery. This has been a great purchase! I also purchased a lithium specific 2 amp battery charger for this new battery. This was an easy replacement for my tennis ball machine - exact fit, same F2 terminals. Performance is much better than prior battery and I am looking forward to the much longer much longer lifespan of a lithium battery. Also so nice to hear that it may be chargeable 8,000 cycles ( assuming I don’t let it get below 20% charge, that I don’t store it at high high temperatures, and that I do long term storage at 50-60% charge). This is such an improvement over the 300 to 500 charge cycles of lead acid battery. Also a big plus is that this lithium battery is 2 lb lighter, so it is a lot easier to lift the tennis ball machine into my car. Suggest purchasers consider buying a cheap voltmeter to charge track of charge status as the discharge curve drops off precipitously at 12.9 volts, as do all lithium phosphate batteries. What a value. I am most pleased.

Batteries seem ok but shipping was terribly slow.

I use this on my kayak. It powers navigation lights, spot light, inside hull lights and fish finder. Full charge I can’t drain it during a 8-10hr fishing trip. I have recharged a few times and it seems to remain consistent without issues. Would recommend. Very light weight.

I got this to power a ham radio go-box. When it arrived I put it on a LiPo charger and charged it to full capacity, then put it on a load tester. It put out 13.02 A/H before the BMS shut down. I recharged it and repeated the test with the same result. Granted this is only two cycles over a short term, but the results are encouraging.

I have these installed in a 24 V, small mobility scooter. After 3 months, one of the batteries failed, they have a one year warranty. I contacted technical support but can't get any place with them. They keep insisting, my problem is that one 12 V battery won't run my mobility scooter. They sell these batteries as a package of two batteries for 24 V systems. It's a twenty four volt mobility scooter that uses two 12volt batteries and ran fine for 3 months. Their response is that my mobility scooter won't run on one 12V battery. Also, they say, if I'm charging it with a 24 V charger, that's what is wrong with my one failed battery installed on my 24v mobility scooter. They tell me that I can't charge one 12volt battery with a twenty four volt charger on my 24v scooter system charged through its 24volt charging port. This is crazy. I can't find any way to contact amazon either to get help from them.

Tamaño perfecto para UPS apenas 1 mes de uso y todo en orden

Me gustó bastante la batería la verdad es que si tarda bastante en descargarse excelente para mis luces de la calle sin problemas las mantengo las horas que necesito y me sobran toca seguir probando pero hasta ahora satisfecho al 100 %excelentes baterías
