I am considering building a project purely for fun. To make it work, I'll need a 1500 (no smaller) to 2000-ish watt 12-volt inverter that's no more than roughly 12" long. It can be up to 12" wide as well, but no more than about 12" on any one side. I cannot make this work, with, say, multiple...

Most budget LiFePO4 100ah batteries are only equipped with BMS's rated for a 100 amp sustained discharge, which is inadequate to power a 2000 watt inverter especially at low charge levels. I'm well aware that in practice you can pull a lot more than 100 amps from most of these batteries for a...

I don't see any other mentions of this device on this forum, so here goes... I've-- thanks largely to Will Prowse-- been happily running a small home solar power system as a hobby for years now, and friends come to me for advice. Recently one was looking for a solar-generator type power box, so...

After a quick search I've found no previous mention of this problem, so... Last night I for the first time used my Bluetti EB3A as an uninterruptible power supply (UPS) for my CPAP. About 2-3 hours into my night's sleep it shut down, showing an "overload" indication despite the fact that my CPAP...

I'm considering building a home-made portable LiFePO4 power station to keep full-time in the bed of my pickup, where I have a 12 volt lighter-style power outlet that only is powered when the engine is running. (I live in Florida and never travel up north in cold weather, so low temperatures...

Hello! I need to work out a way to efficiently charge one independent battery bank from another of the same voltage. I have two 12v independent battery banks that are entirely off-grid. Both banks are lithium iron phosphate. One is fixed and immobile-- it consists of 4xLishen 280 ah, with 100...

I recently bought a set of 16 of the very common 280ah Lishen cells (from SoonBuy, one of Will's favored suppliers), but for budgetary reasons I made multiple orders instead of buying them all at once. My first set of four cells made it here in perfect condition, but the second lacked all...

I'm about to build a 12-volt 280ah battery with cells from one of Mr. Prowse's current favored Ali Express sources, using a 250 ah Daly BMS. I don't have a hobby-charger or any of the relatively specialized bench-gear I see others using to top or bottom balance, and don't want to buy any given...

Is there a plug-and-play product out there that would allow me to connect a standard (cigarette-lighter) 12-volt _regulated_ power outlet to a 12-volt LiFePO4 battery? Or even better, a single plug-and-play product that would allow me to connect several such outlets? I've successfully built...

This looks too good to be true-- the cost looks very low for the claimed capabilities. Anyone tried one yet? Bestsun Powerwall

Hello! I have a 1200-watt solar array on the roof of my sunporch. Until recently, I used 8x1200wh 6-volt lead-acid golf cart batteries for my battery bank. I also until recently owned a cargo trailer with 600 watts of panels and 6 identical 1200wh batteries. While both systems worked well and...

I currently run a small (1220 watt) home solar plant with golf-cart type lead acid batteries as my power-bank. When I bought these batteries-- there are eight of them, and from time to time I've wished for a bit more capacity-- I learned that I had to buy all the batteries at pretty much the...

Hello! I've successfully built and managed two smallish solar setups-- 1200 watts at home, and 600 watts on a travel trailer-- for over a year now using a lead-acid battery bank, and am considering investing in a very large LiFePO4 bank with the intention of adding more panels later when...
