Impressive Battery – Ditched My Heavy EcoFlow for This Camper Setup
Installed this battery in my camper toward the end of last summer, and it's been a game-changer for off-grid camping. Previously, I relied on an EcoFlow Delta Pro—which is awesome quality-wise, but at around 100 pounds and not fitting nicely in the pass-through storage, hauling it in and out every trip got old fast. I switched to this battery, paired it with a 4000W pure sine wave inverter (and the right heavy-gauge cables), plus solar panels and a charge controller for recharging. So far, it's performed way better than I hoped. I haven't done multi-week boondocking yet, but for 3–5 day stretches without hookups, it handles real loads effortlessly: running the air conditioner, microwave, Nespresso machine (should I say "Glamping"??), and other appliances simultaneously with no overloads or shutdowns. The capacity gives plenty of headroom, and the low-temp protection is reassuring for cooler Montana nights. Bluetooth app connection was a breeze—pairing took seconds, and as a tech guy, I love monitoring voltage, current, SOC, and discharge stats in real time during trips. It's satisfying to watch the numbers and know exactly how much juice is left. No more lugging the heavy EcoFlow around; this compact setup stays put in the camper, charges via solar, and powers everything I need reliably. Build feels solid, and the BMS seems to keep things balanced and protected. If you're upgrading an RV/camper to lithium for lighter weight, better integration, and solid performance without the premium portable station price, this battery is a winner. Highly impressed—would buy again. 5 stars!

Solid battery with Tons of power!
I bought this battery to replace the 2 deep cycle 6V lead acid batteries we had in our RV, (which were actually more expensive than this and only lasted 4 years). I also installed a Victron inverter, and I couldn’t be happier! No more need for a generator! Our first camping trip was for 4 days, and we never had to charge the battery. That’s making Coffee, watching TV, running the lights, microwave… At the end of the trip, we still had 30% left in the battery. The build quality is great, and I love being able to monitor the battery in real time on my phone. I can turn things on and off and see how much power they use. The next purchase will be a couple of solar panels and an MPPT charger for complete off grid camping. If you’re on the fence, pull the trigger! This is a great battery and very good value!

Great litium battery
This appears to be a great lithium battery. I bought the 300 AH mini for a solar inverter project. I really like the size and weight of the mini and it seems to perform just as well as the full size. It all had to fit in a compact box shown in the pictures below. The blue tooth connectivity works great and allows you to see full status of the battery including individual cell voltages, load/charge currents, and BMS Mosfet temperatures. It even gives the estimated time left on the battery based on load and the estimated time to charge. I like that it has a 200 amp BMS as some large batteries only have a 100 Amp. I only have a 1500 watt inverter but I plugged in a hair dryer and the battery performed flawlessly delivering over a 100 amps of power. Bottom line, I just bought to two more for another project.

Off grid shed setup, very pleased!
So far I am very pleased with this 300AH battery. The quality appears top notch. The post bolts seem excellent. The values/rates i’m seeing for charge and discharge seem perfect. No issues with the safety features, but glad it has them and I am really enjoying the mobile app support. I hv a 200 W solar setup with 300 ah battery and 2k pure sine inverter. Based on my region and access to sunlight, I’d like to purchase another 200 W panels (400 w total). Currently I only get about 8-9 amps max for 2 hours, so my charge rate for this giant is roughly 10-15% a day. I’ve set this up in my shed and tested running the shop vac and saw for an hour. Everything is working well together!

Very good value.
Very good value for money. The BMS works well, I inadvertently tested the short circuit protection. The battery went into self protect mode, then reset itself after 10 minutes - nice. The Bluetooth app is not available through Google play, which meant I had to bypass some security settings and also deal with some Chinese tick boxes.

Excellent battery!!

Great value!
I'm very impressed so far. The capacity (according to their own app) is dead on, cells are staying balanced. Size was accurate. I've only been using for a few weeks so I can't comment on life but seems to be holding up very well. I'm most impressed with the app. It not only shows voltage and soc but also gives a live throughput which is great for knowing what you use and create with solar. Also creates a histogram if you leave the app running. I wish I could turn the Bluetooth off. I wish the app was a little prettier and user friendly. I turned off balancing in the app and can't get it back on (don't do that!) However, at this price so far this seems like an amazing deal!

It’s Junk!!!!!!!!!
Do not buy this ?!@&$ Junk!!!! Mine died after a few months. I reached out to Amazon they lied and stated that it’s covered order their “A to Z” program. I guess there’s a new letter after Z now! They did nothing.The seller states that there is a 5 year warranty. The seller keeps telling me a pack of lies saying, That I need to discharge the battery first to zero percent then recharge. The battery is already at Zero percent!! I tried everything to get it charging ,Solar ,multiple battery chargers. Do not buy this piece of garbage!!!! The seller states that there batteries have 15,000 cycles I got a lousy 5 cycles before it took a major dump!!
