Incredible Value LiFePo4

The Watt Cycle LFP batteries represent an insane value to quality ratio. Read about them here..

Good information here. It is good to know that you have an Amazon storefront with tested stuff. I will benchmark that for future use.

I read your article on the Power Queen debacle. I fully agree that an LFP in a sealed case with no Bluetooth connection is a terrible idea. That is why I do not like the Battle Born batteries. I have heard of too many that have dropped to 50% of rated capacity because they cannot be charge to more than 13.6v without the BMS disconnecting.
I really like that this new mine is BT and that the case can be opened. When I got my sealed 460Ah battereis, one of them had an imbalance of +300mv at 13.7v and tested at only 445Ah. Because it had a JBD BMS with BT I was able to turn off charge balance so that it balanced when it was NOT being charged. I then charged it up until the highest cell got to 3.60v and turned off the charge and discharge FETs and let is balance for the next 24-hours. After doing this daily for a few weeks, I was able to get the imbalance down to 50mc at 14.2v. I then tested capacity again and it came to 480Ah.
Now at the beginning of each year, I do the passive balancing a few times and they are good for the season.

I am by no means an early adopter. I like testing things too.

But by the next time I need a battery, the knowledge base will have grown even farther, and the cost/value balance will have swung farther, so it seems unlikely I will ever buy lead again, other than for my car. Lead still works for dumb, sub-freezing-capable starter batteries.
