PUPVWMHB 12 V 300 Ah MINI LifePO4 lithium batterij, Bluetooth lithium batterij, 200 A BMS, tot 15000 cycli, max. 3840 Wh energie met Low Temp Cut Off, perfect voor RV, zonne-energie, trolling motor

The battery itself arrives very well packaged and seems to work well but the app seems to have many bugs. In the brochure that comes with the battery there is absolutely no explanation of how to use the app - how to set parameters for the battery using the app etc etc.. There is nothing about cell balancing or how to turn on or set the temperature protection.It may well be that this is all automatic, but it is not made clear. In fact, if you read the reviews on playstore it is clear that there are many people who encounter problems.

Seit ein paar Tagen im Wohnmobil verbaut und wir sind bisher begeistert. Gleiche Maße wie andere Akkus mit 300 Ah, aber eben nochmal 10% mehr Kapazität. Satte Ladung, nimmt hervorragend Strom von der 500 Watt Solaranlage an, perfekt. Der Kühlschrank verbraucht über Nacht gerade mal 3% der Ladung. Die App funktioniert auch wie erwartet, alles bestens. Der Urlaub kann kommen!

Exceeds the 300Ah spec and has a generic Jiabaida/JBD BMS, fully configurable if needed.Balancing settings were not to my liking for LiFePo4, but easily changed.The low temp settings otoh were great and it pulled 200A for a good while without breaking a sweat.I have no clue why manufacturers allow balancing already at 3.300V, but it had a generous delta setting on top of that so it looks optimized to handle really unbalanced situations. I've seen worse decisions.

I got this battery to run a bilge pump from 8-10 hours straight running at 11 amp draw and so far its done just that. I researched various batteries for the application I needed and it turns out I needed a Lithium Iron Phosphate battery that can handle a constant draw and this one is the one I chose. The bluetooth is a nice added touch to keep an eye on it as its in use.

I just purchased a 300ah battery from this company and got a real scare when it came but not the companies fault, I think the problem was the app, when I downloaded it the app was saying the battery was only a 200Ah battery and I reached out to them and actually learned a few things, the settings that were loaded in the app were wrong for this battery, after contacting them they were able to fix the problem by remotely connecting to the app and putting the right settings in it, now it's showing a little over 300Ah and is so far working great, the battery looks really good and lighter than I thought it would be, I am really pleased with it right now, I hope nothing changes when I start to actually get to use it, I have it installed in a camper van and will traveling next week and will get to test everything out, I have this battery connected in parallel to 2 -100 AH batteries which gives me more than enough power to run my AC, frig and lights and fans and a tv until my solar recharges everything, anyway I would highly recommend this battery for anyone looking for a larger battery other than 100Ah batteries, I will update my comment on it's performance after I get back home but for now I am really pleased

Battery arrived with 52% charge, looking good so far. I connected it to my two 100Watt solar panels but it will take a while to charge this massive 300Ah battery. I finally feel that I have real backup in case of power outages. I can easily run my child's nebulizer if needed and plug LED lights and fans for hours and hours. I already had a battery charger and an inverter, so it didn't make sense for me to buy an expensive "power station" that easily costs 3 times as much as this beauty. Almos forgot, the bluetooth enabled app shows you all the details you would need to know at any moment (see picture).
