I have an offload camper it is perfect for my needs

I recently went camping offgrid in California. I utilized this standalone 12v 100Ah to power my diesel generator, running it all night long and enabling the inside of my tent to be 72F while outside it was 23F. I also powered some lights while I camped, using this battery. It shocked me how long it lasted, given the draw of power from the diesel heater all night long. Would absolutely buy again, given its portability and performance.

Been running a four pack of these for almost 6 months and fully powers my home. Highly recommend these batteries

I made a portable charger out of one. Great little battery.

Replaced my 2 AGMs with 3 of these. Running the house on them now. Ran the Microwave, heated up some soup, running the washer now. Tripled my capacity. Gonna save me money.

Bought 2 (4 packs) for a total of 32.15 KWh storage for an off-grid 15 kW DC solar paneled, 48 volt storage riverfront get-a-way. Always charge batteries individually to 100% SOC before connecting in series/parallel configurations.
Make sure charger (in my case is part of inverter) is set at a maximum voltage level lower than will let any single battery in the series string (4 in my case for 48v) cut off the charge voltage MOSFET. In my case I found this to be 54.9 volts or 13.725 for each of 4 batteries in series.
Very satisfied with purchase value and especially the Bluetooth monitoring of each battery.

Plugged in 12v camping fridge to test. Battery hardly discharged for several hours. Initial reaction is positive.

Arrived well packed, with four bolts and two caps and detailed user manual. Specs on pics. I will charge and discharge a few cycles with wall charger and solar. After a while I’ll share the performance results. Seems like a good value deal.Update: Humsienk 12.8v 100ah holds 13.3v at 50-60% state of charged capacity. Full charge reaches up to 14.02v, gets stabilized at 13.85v at 100% capacity.Humsienk customer service responded within 24hrs and conducted supportive knowledgeable assistance.

They arrived in perfect condition.

Fast delivery and good product at a great price. I have not used it but I did charge it and am awaiting camping in a couple of weeks to use it. , just what I needed.

Delivered on time. Tested a few times with a 12 volt trolling motor I borrowed. Worked very well. I haven't tried it on my 36 volt TM but I'm sure they will be fine.

Arrived on time, have not used this yet but it was charged most of the way to 100% ,time will tell so far so good! good looking batt, and very light compared to a lead acid. very happy+++++!

The batteries were received quickly after order. the packaging was more than sufficient. the batteries come with 2 different length screws so you can connect more than one device.

Hurricane hit and this not only work but they work well beyond expectation. I've ran them non stop for 2 days and they power everything I need in the house.

Shipping was fast, price was the lowest around. It’s a great battery, powering my RV with ease.
