I ordered a EG4 48v 100ah battery from Signature solar. After modifying a couple of 2/0 lugs to fit within the battery terminals of the unit, everything got up and running pretty well. Then one day we turned on the vacuum cleaner. This isn't some industrial-sized piece of equipment, this is an...

I purchased two Li-Time 100ah "Trolling Motor" batteries. I noticed when charging them with a regular AC to DC shore power charger that they'd be putting in power at around 30 amps until they got to 13.9 volts. Then the amperage would instantly drop to zero and the voltage would read 14.4 (the...

I currently have a 48v primary system in my RV, and it's working great. I also have a 48v to 12v converter which supplies me with 12v for things like lights, water pump, etc. I've been adding more 12v stuff, and I have plans to add significantly more, such that I'll be beyond the rated...

Let's set up the situation: A charger is running (could be solar, DC-DC, or shore power) and is outputting 14.something volts (generally 14.2 or 14.4 depending on charger) All batteries are in over-voltage protection mode (because they're sucky grade B cells and no amount of top-balancing will...

Anyone have any recommendations for a 16s balancer? I already have a 48v bank in place, and am having a hard time finding something that can do 16s. I really like the 8s model on Amazon where it shows the voltages of each cell, and it's cheap. The fact that Will uses it in his videos seems...

I'm building a tiny LiFePO4 battery bank with some 12v outlets, USB outlets, and a voltmeter. Basically an over-sized USB battery bank. To charge the batteries, I found a nifty buck/boost converter that would take anything from 8v to 40v (dc) and convert it to 13.8v DC. This will almost fully...

So I've done some Googling and Amazon searching and so forth, but I must be searching for the wrong thing. I'm looking for an extremely simple thermostatic switch that I can use with a 80mm computer fan. I want it to turn on (close the circuit) when it's around 80°F or more, and turn off when...

Are there any battery brands (besides Battleborn) that match capacity and pre-balance the cells before they ship out the batteries? I'm looking for a quality battery and Li-Time and SOK appear to not do this. At this point, I'm looking for a simple 12v, 100ah battery, with low-temp protection.
