HumsiENK 12V 150Ah LiFePO4 Lithium Battery BCI Group31 Bluetooth- Built-in 110A BMS, Deep Cycle Battery for Solar, RV, Marine, Off-Grid Applications - 15000+ Life Cycles, Safe & Lightweight

I bought these for my boat. I watch a few videos on them, they opened them up and they seem to be well made and work well at a great price. The app works easy for me I can see battery levels, it is one at a time but that's ok. I am looking to upgrade my 12 volt trolling motor on my boat, when I do I will buy more of these to meet the needs of the new 36 volt trolling motor. Because they are so much lighter I can run all my electronics are on there on lithium battery separate from the trolling motor. Thanks.

Excellent battery

Good value and quality as described with quick delivery. Used as storage cell for off grid solar energy and is as described.

Battery is working as hoped for/expected! We bought this battery along with a 1000 watt pure sine wave inverter to use as a power pack for our cargo trailer toy hauler/camper conversion...mainly to use with our 48 quart Wolfbox 12/120 volt car refrigerator and it ran the refrigerator for approx. 24 hours non-stop via the 12 volt plug connection. Note 1...I used a power plug-in 120 volt meter to check the wattage pull on the battery with the refrigerator on it's "Max" setting and it was pulling between 48-54 watts. Note 2...the battery and inverter ran the lights (two 40/42" led light bars) with no drop/hesitation. Note 3...we tried to run our microwave (1400-1450 watts) and it started up but the power dropped down and you could tell...this was probably because the inverter was set to normal and not the heavy load setting??? I plan to try it on the heavy load setting later on. I hope that it will continue to give us this type performance for our camper/toy hauler in the future and for an acceptable amount of time. Hope the information above was helpful!

Great Battery for my RV replaces flooded deep cycle batteries in my Motorhome. They make it usable for boondocking but be aware you need to replace your RV voltage converter to one that is compatible with LiFePO4 batteries but well worth the price. If you only use 1 get the 200A BMS if you want to use it to start your Generator. Make sure it will fit in your battery box I had to modify mine but it was not to difficult to do.

I purchased these batteries and few months ago and had my system professionally installed less than 4 months ago. 4 days ago, one of the batteries BMS started malfunctioning and won't allow it to charge, and it flips on and off in discharge protection mode. I reached out to the manufacturer with emails. They have called me and request that I send an email. Its just a runaround and have gotten nowhere but 4 days of no electric. Edit** got a response, but it's 1 email per day, with no resolution so far. Just the runaround. It was expressed that I have no electric day one and it doesn't seem to matter. Just getting excuses. Worst customer service experience I've ever had. They even said there gotten no emails from me... see photo.

Used these batteries ti upgrade my Ryobi ZT540e from lead acid to lipo. Batteries worked perfectly. The only diferance was that these batteries are about a quarter inch taller so it was a bit challenging to get the lock down frame back on other than that they were an exact fit. If you are purchasing these batteries to upgrade from lead acid remember to purchase a new charger that is compatable with lipo batteries otherwise you could ruin your lipo batteries. Also remember that a charge indicator for lead acid batteries will not indicate properly for lipo batteries so you will need to replace that with one that is compatible with lipo batteries. Final outcome; my Ryobi ZT540e now runs better than the day I bought it. Power level is much more consistent throughout the entire time i am mowing my 2 acre yard plus the new batteries are about 200 pounds lighter so the mower is probably about 20% faster. If you are looking for a battery upgrade for your Ryobi ZT540e, this is the way to go.

It looks like a quality lithium battery. Just getting installed with a solar package so don't know how it is going to work. Got my fingers crossed.
