DC HOUSE 12V 6Ah Lithium Battery, Rechargeable LiFePO4 Battery with 3000+ Times Deep Cycles and BMS Protection for Fish Finder, Power Wheels, Scooter, Light, Kids Car,UPS，

Bought this to use with my portable depth finder, it is very light and last a long time between charges it and my depth finder fit in a small tool box making it very easy to switch between a boat and canoe.

In my application, an energy generating bicycle, it works well replacing an SLA. The specs work well with 14.5 V lithium charger .I am purchasing 4 more for my small solar charger. If that works in a parallel fashion, it is a real bargain. The simple instructions are well provided with illustration. I will review again for the parallel project and if that lasts a year trust them on a 50 amp hour.Upgraded to five stars because they work seamlessly in parallel with #12 wire and soldered connections. My tests with 4, 12, and 16 in parallel deliver about 95% of rating after losses. No duds so far. The switch from lead acid to Lithium iron Phosphatewas smooth and my Renogy Adventurer Solar charger set to Li. and 14.6 volts is not overcharging.

I bought this on sale for $18, so it was a great deal then. The battery is very light, so I don't know if it's 6Ah rating is real. However, it is working fine in a solar powered radio beacon set-up.So far this battery is doing the job I bought it for. The battery is outdoors in a case to protect from moisture and rain, but it experiences the heat and cold out there, which may reduce its life. But at $18 it would still be a great value if I got a year or two out of it in 24/7 operation. This is a great value and I recommend it. I will update in a year (10/2024) to let you know if it survives my application.

This light weight battery is in my R/C airplane field box. I had hoped that it would be good for running 12V starters. Ir does OK on smaller glow engines up to .60 cu in but it can't give up its power fast enough to start larger gasoline engines in the 30cc+ size range. It's not a fault with the battery. LiFePO4 batteries just aren't capable of releasing large bursts of power quickly. For running a power panel and glow driver it's much better than a lead acid battery. It holds its charge over extended periods without charging and it's so light that it's hardly noticeable in my overloaded field box.For those interested: A 2600 MAh 3 cell LiPo runs my 12V geared starter and will easily spin a 35cc-40cc gasoline engine.

These have worked flawlessly in my RM300e Ryobi lawnmower. Just make sure to balance them occasionally and you have a mower that will last forever

I bought two of these for powering my trail cameras around my property. They worked well for awhile but despite being hooked up to a solar trickle charger they both died after approximately 3 months. This wouldn't be a big deal except that now they won't take a charge at all from any charger. From reading other reviews it seems that some of these batteries are great and others quit like mine did. I suppose it's the usual risk involved buying anything Chinese in origin.

I intended to use this as an AGM replacement in a UPS. I measured the cutoff voltage of the UPS (10.5 VDC) and ran controlled discharge tests on this and the normal AGM UPS batteries. Literature suggests that a LFP battery with a BMS can be discharged to 100% as the BMS is supposed to turn off the battery before damage occurs. The BMS cutoff is 10.0VDC, hence the 10.5 UPS cutoff is reasonable. I ran tests with a constant current electronic load and set the cutoff to 11.3 VDC. Fresh AGM 7AH batteries consistently produced 4 AH +-. With the same test parameters this 8 AH battery consistently delivered 7+ AH. Given that 8 AH AGMs now have a retail price (Batteries Plus) of $55, this LFP battery is the only way to go.

I tried using this battery as a drop in replacement on an APC UPS and had mixed results. The battery would slow charge when the UPS was plugged into the AC, but when the battery reached a full charge a relay in the UPS started clicking on and off.Most likely it has something to do with the BMS inside the battery as the UPS was designed for a sealed lead acid battery.Otherwise, the battery functions well in other applications such as lighting and low current uses.
