Wow! I adore talking with Mark, he is a product support specialist i assume. He was generous in rendering their assistance. Grateful for your swift response to emails with well balance explanations.
These guys are great. Just when I thought all electronics was out of China. I have had a good experience.
Very informative website. All info is offered for free although I can see there was actually a lot of effort put into obtaining it. I can see they are really passionate about what their doing.
These guys have technical expertise to help you spec the perfect product. I needed a charger to charge my 48 volt battery bank and could not diffretiate from the several products offered online. (I am not an engineer) They provided me with several options to choose from, and thoroughly explained the benefits and downfalls of each the products. Unlike other web-based platform, which are focused on selling off-the-shelf items, they provided me with a custom solution that best fit my application.

Ordered a 12v to 5V converter from powerstream. They shipped it out to me and the unit I received was dead on arrival. I showed pictures of a voltmeter connected to it showing no voltage across the thing and they finally agreed on sending me another one. They told me to send the defective unit back (AT MY EXPENSE!?), which I did, and provided a tracking number to them. At this point in time, they sent me a new unit. The new unit did work (although not as well as I would have liked, it was not isolated as advertised and was still getting feedback but I didn't want to deal with their poor customer service again). Now that being said, all I did was ask to be reimbursed for the return shipping of the defective item. They said they would reimburse me, and despite several emails that I have sent them about it, they still have not done so. They have quality control problems and poor customer service. I literally paid for shipping twice and it ended up taking forever to get an item that works. I do not recommend ordering from them.
****UPDATE: In light of the refund and the response from the company rep indicating that they have taken my feedback into account, I have adjusted my rating. Thank you and I do appreciate it.
How wonderful to hear from folks that know what they are talking about. Refreshing, to say the least. More power to you!

**Update 7 Months Later (Nov 2018)
Installed, and works beautifully! Even when my fridge runs the 2nd battery dead, my rig starts every time! No issues with winching while the truck is running (i.e. the isolator closed and connecting both batteries)--see new pic for funzies. I highly recommend this isolator, especially for the price! When I get a new truck, Ill be running a dual batt setup and using this isolator again.
**Original Post
I am putting together a dual battery system for my 4Runner, and as I learned more about the components, I began to develop more specific questions than can usually be found on typical FAQ pages. Thus, having previously come across this company and their very affordable battery isolator--and, more importantly, the very clear and thorough product information page--I decided to give them a call. The gentleman I spoke with, Matt, was very knowledgeable on the product, and answered my specific questions about things like the effects of a winching load potentially drawing power through and around the isolator, and exactly how it switches from isolating to dual-charging. I will update this review once I actually get it all working, but so far I have no expectations that the battery isolator will not work as advertised.
Excellent articles on this site with original research describing how lithium ion batteries work. After pouring over many many sites that tend to mimic each other it was nice to find some science behind the explanations. I understand the technology now in a deeper way.
I called to ask for some help regarding Lithium Ion Batteries. I was sent to a sales person who was very short with me. He was arrogant and seemed like he did not want to waste his time with me. If I was not already a battery expert he did not want to condescend to help me learn. Very disrespectful and cocky attitude for a business who depends on customers and sales.
This is a fantastic one stop site for anyone from hobbyist to professional. The wide selection caters to almost every need for development of a project including quality materials and hard to find resources. This along with great communication and technical knowledge has easily earned 5 stars for going above and beyond the assistance I expected.
