How cool is it that the prices keep coming down, quality is going up and capacity is increasing - all to the point where reviewing them gets "boring"! Your comment that they are "boring" is one of the most reassuring things I've heard!

Nice job Will. As an EE (retired) I really appreciate your approach.

cant be half bad if they are willing to send you them for free for a tear down and video. Must be confident in their build and quality. Pretty good review thanks.

Keep up the great reviews. Always appreciate your focused diligence.

Will I've watched so many of your videos and really enjoy them. More importantly as a non tech head, your easy explanations are so valuable. Many thanks

Power Queen contacted me after my battery shipped to let me know it was coming and to make sure I knew how to contact them if I had any issues. It arrived on time and we well packed. Don’t ever recall any other product company doing that?!

Thanks again Will. Always interesting to see the similarities between different batteries.

Good day Will. Another great video and definately not boring to your viewers. Been watching for years now and learned enough to power our entire property off grid from you and a few select others. Special request: please do a review / teardown of the new model EG4 "waterproof" battery. Weve been using them for a month now in our system and they've been performing perfectly. Capacity test and and internal cell balancing has been right on the money. Love them so far but it sure would be nice to see the internals and hear your detailed thoughts on the cells/BMS and overall build quality. Thanks for all youve done & continue to do.

another great video Will. As always just the right balance of data and facts mixed in with your well informed opinion and pleasant personality. Also loved your comment at the end about Chinese companies just sending their stuff out without follow up and the American companies doing the opposite.

Thanks, Will. I really appreciate your "tear down" videos. You are doing all of us a great service. Because of your many tear downs, I would feel comfortable buying cheap batteries like Ampere Time and Chins if/when I was looking at installing another battery bank. Keep up the fine work.

Ampere/Litime customer service seems quite good. I've asked them about 20 questions and always get a fast response within 24 hours max. They will also offer you a further discount on their products if you negotiate and spend more! So far 10/10 service

Thanks again Will, I couldn’t find a difference in the plus vs no plus models other than price. Great job.

Someone in another comment said the "plus" model has a higher discharge rate capability. I don't know...just passing on what I read. 🤷‍♂

Thank you for doing these break down reviews, I always learn something.

Glad Will pushing servicability for years resulted in SOK building an outstanding battey line. Their 200 amp hr is small enough to fit FOUR on their side, (800amphrs!) on top of my rear wheel wells (two on each well) on my Vanlife converson van. But still underneath my low bed frame, which is just outstanding. Battleborn has some serious competition.

I bought two ampere time on your recommendation. Two 200ah batteries. I bought one in September, last year, and found it just wasn’t enough. So for Christmas, I did a deal with the warehouse and picked up another 200ah. Super fast shipping, since they have a warehouse in California. I am totally pleased with these batteries. Since we store them in the storage unit of our 5th wheel, they never get below freezing. We full time travel, so we also stay away from cold weather, That’s below 70’. I also have a Victron charge controller, and a battery Sence, so I keep a eye on the battery temp, and the charge controller is set not to charge below 38’ Thank you sooo much for your reviews. We really appreciate your work.

I was kind of freaked out when you started cutting into the side of the battery. Then I noticed the saw you had. Those little saws ,are great. Buy every blade. So easy to handle . But really loud. Ear plugs job for sure. Back in my younger days, I used the giant floor scrapper version. I made a LOT of money with that thing scraping up glued flooring.

I have a 3000 watt inverter in the trailer (go power also purchased in 2014 and still going strong) and want the 12v 200ah battery to help extend the buffer for high power devices (TV, Microwave, Gas Heater, toaster, etc) I had 200 watt solar panels for the 12v 100ah stark since 2020, works great with the morning star mppt-25, but will be adding a 3rd panel for 300 watts on the 12v 200ah powerqueen. I'm so happy prices dropped, I paid $1100 for my stark power 12v 100ah back in 2014, but so worth the investment as I never had an issue as I did with the Lead Acid batteries originally on the trailer. Off grid Glamping has become very awesome with all this new tech!!!!

Thank you Will for another battery video, I appreciate the always current info on DIY battery prices, and the precise approach you bring to cutting them open to show us what's inside them. At $1040, the 300ah Ampere time is now on my list to buy in September. With the lengthening days, my present 200ah at 12 volt system is normally full by sunset, but come midwinter the extra will make a huge difference. (2004 Toyota sienna)

Thanks Will you’re always helpful.

I have the 200ah plus model of this brand on my boat. It's charged by a 700 watt solar array linked to a victron solar charge controller. It's a great battery. Powers everything on the boat without any issues. This includes a deep freezer, lights, fans, a small inverter, and a water pump. The low temperature cutoff really is no issue on the boat as I live in Florida and the battery sits below the waterline. Even if the outside temperature drops below freezing the warmth of the water still keeps the battery space above freezing. For boat owners this is a factor to consider

Ampere Time has been purchased by Li Time. Li Tiime will honor all warranties that Ampere Time issued. These are darn good batteries.

Power Queen and Ampere Time, all these use prismatic LiFePO4 cells. It is very convenient for assemble, however, there two issues, one point is heat dispassion won't be good, another point is the capacity, once one cell failed to work, that the capacity will drop significantly.

Too expensive for me I thank you for turning me on to Docan Power I bought 16 LF280K LiPos4 for $2200 and they are so awesome thanks for all you do for our community regards, rick

Great job

High discharge rates open up a new world with things like microwaves and tankless electric water heaters. I would have ordered a server rack but they don’t make a server rack with a 200A discharge rating.

Sorry for my ignorance The problem with temperature with these batteries is if it get too cold isn't over heating an option

Discussing the weights would help. Reduced cycle life is Ok for most applications but if the cheaper cells are also found to decay faster by the calendar, that would not be cool. Unfortunately without a world-class accurate coulomb counter only time will tell.

Ampere Time PLUS models all have a high amperage BMS. The standard Ampere Time batteries have a 50A to 100A BMS.
