      Great battery in small package, tons of available power!

      VERY IMPRESSED so far! I ordered 2 of the NEW 300 amp hour MINI lithium batteries, and they are working perfectly. I ordered them Friday, October 18th, 2024 and received them both on October 25, 2024 in perfect working order. I started off by testing 1 quickly then placing it in a freezer set to 26 degrees Fahrenheit to test the low temperature charging protection, left it in for about 12 hours and hooked to a charger and it would not allow a charge to pass! I allowed it to warm up slowing and then tested again and it then would allow charging again. Very happy to see this feature working! Being able to use my system in freezing conditions is very important to me and this helps to know my investment in these batteries will be protected!

      The second battery I began charging up off my 1000 watts of solar panels and Victron charge controllers I have in/on my fully converted cargo trailer camper. I use it as an "off-grid baby camper" as I call it. We use the camper (I built in spring 2020) for family trips, camp outs, cross country road trips, and "deer camp" where we expect it to deliver all the comforts of home in a small package while going wherever we want. We depend on the solar and lithium batteries along with chargers and inverter to keep the food in the fridge cold, my family and pets cool in the air conditioning in the heat of summertime, electric heaters and diesel heaters keeping us warm in the winter. Along with being able to run a coffee maker in the morning or making microwave popcorn for watching a movie on the TV before bed.... all while being able to camp anywhere we want without the concern of pluging in at a campsite or having to listen to a noisy and stinky generator. So far the available power in these batteries compared to my previous lithium battery bank I can instantly tell these batteries will be a major upgrade to my system.

      My previous system consisted of 465 amp hours of lithium-ion in 3 parallel batteries. Connected in my system with a 12v Giandel 2200/4000 watt inverter it powered all our needs but I noticed a slight delay in developing power on some higher demanding appliances. With my limited time with these new Wattcycle 300ah Mini's, I've so far hooked up some power tools in my garage and a microwave in my trailer and they all have preformed like they were plugged into a regular outlet in my house. That's with only 1 battery hooked up! I've already been so impressed I've purchased a third to make my system 900ah!

      The compact size of these 300ah Mini's is remarkable! Each of them is about the size of my previous 160ah lithium-ion batteries. I am going to be able to double my total power in the same space. They do weigh more (about 57 pounds each) than my previous batteries, but that is to be expected with their higher density..... or whatever they've done to pack so much power into such a small battery.
