  • Great quality 24v 100ah battery
Color: Compact 24V 100Ah Size: Compact 24V 100Ah
I really like the weight and compact size of the battery. It charged up perfectly and was in good condition when received. The handles on the battery are also a nice touch, making it easier to handle. Came with two lengths f screws as well as washers and lock washers which is nice, as other batteries ive got in the past come with nothing. The bms functions well and does everything it says it does. I really really liked that they included a manual that stated all the specs of the bms, such as cutoff voltages, temp cutoff, etc. such a good price for this battery for such good quality. The one thing I was a little disappointed with was them shipping using fedex however and wish they could use ups or even usps. I knew my battery had arrived when i heard the loud *thud* of the fedex delivery driver dropping it on my porch. Tracking from fedex is also hit and miss. Really glad the battery was packaged so well with thick dense foam that protected it when the delivery driver literally dropped it from waist high onto the ground. Over all happy with my purchase and will order from them again. Really hope to see larger capacity 24v batteries from them in the future. ... show more

  • Impressive battery with built in ampHr compared to others
Color: Compact 24V 100Ah BT Size: Compact 24V 100Ah BT
I've used this battery for my trolling motor and it's great. I've replace this unit with 2 x 12v lifepo4 battery that didn't have bluetooth. The thing I find nice about this battery is the built in ampHr for capacity, I was tired of looking at volts trying to understand how much more juice I have in it. This is a great battery, it's rare for batteries to also have the ampHr build it, save you money so you don't have to buy a shunt ... show more

  • Great for Hook Reveal 7ts
Color: Compact 12V 12Ah Size: Compact 12V 12Ah
This battery is for my Hook Reveal 7ts fish finder on my kayak. . After using a different brand for similar battery (12V 7.5Ah) for a year and half, that battery would only last 3 hrs. Since it was 30 $ battery I told myself for 1.5 years that was ok and ordered another. The new battery was used twice and only lasted 1.25 hrs and then almost 2hrs. I fish 4-6 hrs, so I sent it back and began a search for similar battery that was same size as it has to fit in my kayak battery holder in the sealed hatch. I found this brand XYNZ and was happy to find the right size with more power 12.8 V 12Ah and consistent reviews and for only a few dollars more. It arrived a lot early then originally schedule (Yeah). Was packaged very well and came with a nice little manual. I followed the instructions and charged it up. Took it out to fish and it lasted around 4 hrs without any problems. So I didn’t charge it to see how long it would last and took it out on day 2 and it lasted another 4 hrs. So I took it out on day 3 and fished 5 hrs without any problems. At this time my friend was here and used his tool and it was 11.8V. So I put it on charge. My friend also helped me to set up the voltage to display on my fish finder so that I know when it gets to 12V and can charge it up when it reaches that amount. I will follow up if I have any problems and also will follow up in 1-2 years to let you know if it’s still going strong. My other battery should have lasted a lot longer than 1.5 years! This company sounds good and has a 3 yr replacement on it. ... show more

  • Reliable and Compact!
Color: Compact 12V 310Ah BT Size: Compact 12V 310Ah BT
Have been using the battery 310Ah as an emergency power station for almost 8 months now and I've had zero issues. Battery life lasts me a couple weeks with steady use with solar, and has proven to be an excellent value for the price. These are compact batteries and not all that heavy, so they're easy to carry/organize. The posts are an M8 style and come with short/long threaded studs to meet any need you may have which make them easy to setup! Would definitely purchase again. ... show more

  • Mine only take a partial charge 😲
Color: Compact 12V 12Ah Size: Compact 12V 12Ah
Bought 3 of these and couldn't figure out why I was running out of battery halfway through my flights. I finally put a voltage meter on them during charging to understand what was going on. Either a bad batch of three or incompatibility of their BMS systems with well respected tried and true Noco 5 and Noco 10 chargers in lifepo4 mode. The XZNY top out at 12.5v (less than a 20% charge) which was enough to power up my instruments but obviously left me high and dry no pun intended 😲 ... show more

  • Still has mixed stock, but still great battery
Color: Compact 12V 12Ah Size: Compact 12V 12Ah
About 6 months ago (Nov 2024), I purchased 2 of these for a small standing scooter. They were the 10A BMS model. They worked perfectly in the scooter, and I performed a test in my UPS and they seemed to work fine at the load I had them at (~230W/9.5A), so I planned to purchase more for two UPSs I need to replace the SLA batteries for. I come to find they've since upgraded this to 20A BMS, works for me, I bought 4. What actually arrived was not what I expected though. Two of them were the 20A model, and two were the older 10A model. There's no actual markings on the battery themselves that I saw which would indicate the BMS size, so I referenced the spec sheet on the included user manual. I ended up exchanging the 10A ones, and the replacements that arrived were also the 20A BMS I expected. They are now installed in two APC UPSs (1000VA and 1500VA) and work fine. The load on them is about ~250W each, so the current draw should be well within the BMS tolerance. I haven't tested the actual runtime with these yet, but I don't expect worse runtime than with the AGM ones. Anyway, I recommend these batteries as safe alternatives to AGM/SLA: They are lighter, and aren't fire-prone like other Lithium technologies; however double check the BMS rating in the manual when you get them, to confirm they're the 20A BMS, assuming you need that size. EDIT: 27 Sep 2025 I finally got around to testing the UPS. At 230W load (~35% as reported by UPS), I was able to get just over 56 minutes of runtime with an APC Back-UPS XS 1000. That's not a typo, nearly an hour of runtime! I can't remember what runtimes I had with SLA, but various online calculators say to expect around 20 minutes of runtime with that load. The test was simple, and involved running a stopwatch on my phone while letting my computer sit at the BIOS setup until it died (to keep idle power usage fairly constant and reduce risk of data corruption from unexpected power loss). ... show more
