ULTRAPOWER 4-Amp 14.6 Volt LiFePO4 Battery Charger,12.8 Volt LiPO Lithium Battery Charger,Smart Charger Maintainer for Cars,Motocycles,Golf Carts,UAV,Fishing Boat and Deep Cycle Batteries.

***I've only had it for today. If the unit lasts, it is worth every bit of 5 stars and above!***This is by far the best lithium charger I've ever purchased for the money. In less than 4 hours, it has brought back to life both a Shorai & NOCO battery that the OEM chargers were incapable of doing. Granted the package is very compact, but my only suggestion for improvement would be that this "kit" provide true battery/jumper clamps instead of 1 of the 3 other options it comes with.Seriously contemplating purchasing a 2nd unit to be the default chargers for all my LiFePO4 batteries in our household.

Back FROM THE DEAD 2! My voltage on my dead 12V lithium battery measured in the Millivolts not Volts!!. YIKES My other car etc. charger which says it charges LFP too which worked before on this same Lawn LifePO 12V Tractor Mower Battery did not work this time as voltage was too low for it. This little dedicated LifeP04 DID it! It resurrected the the battery. Possible my riding Mower is not charging this correctly or not at all like it did last year. Hmm anyway thanks!!!!

I specifically wanted the quick connect option so I can easily maintain a motorcycle battery . This leads me to the only gripe I have there are like four ways to connect and not the one that it should the ring terminals with the 10 Amp fuse to sae now I see a nice little cut in cost without any problems because I'm not sure why it seems we have power connections for a maintainer I would ditch the DC pin plug and the rca video style plug the claw and ring terminals and everything this thing is ment for can be achieved because the connection options are really solid nicer quality wires and plugs honestly so overall there really is nothing to complain about its simple plug and go with nice protection features .Thank youI also like there is not some goofy weird name on this product I'm a little picky on names that look like you just closed your eyes and hit the keyboard when filling out product name box. lolSending positive vibrations to everyone

I upgraded my rc robot from sla to lifepo4 batteries and was recommended this charger. Unit is well made, but does get very hot. My previous charger was installed in my robot so that I could just plug in an extension cord, but unless I can add a heat sink, I'm hesitant to use this the same way. The charge indicator is nice, but doesn't work when not connected to ac power.I'm thinking heat sink with a cooling fan based on how hot this gets.

If you have a LiFePo4 battery in your Go-Kit this keeps my 24 amp hour battery charged quickly and with a small size packs easily. Get one, take it from a Ham 73.

works great for my 12 volt lfp batteries. yes things get a little bit warm that's normal. and for those griping that the left set of LEDs don't like that's because they're NOT LEDs. it's just a label that shows the charging states of the real LEDs to the right! 🧐. there's even a card that ships with it now that explains that.

My Lifepo battery was reading .75 volts (that is not a typo, less than 1 volt). I tried my Noco GB70 a couple times and nothing happened. I hooked up the UltraPower and the 4 green lights started to light up in sequence per instructions. After about 3 hours, it was still trying to resurrect the battery, but I went to bed. This morning I discovered it is completely charged and showing full power! I had given up on the battery, but thought I’d try the inexpensive UltraPower as a last resort and am glad I did. I agree that the gator clips are too small, but I did not experience any excessive heat on the unit. In fact, it seemed cool to the touch. Maybe it gets warm while working and then cools off. I Highly recommend this device! P.S. the Noco is fantastic for starting a dead car battery, not so much for my smaller LifePo trolling motor battery.

This was fantastic, very handy and sufficient for recharging my phone several times on one charge and for recharging my bike light when it is low. i said was because I lost the darned thing. and now I will buy it again.
