Inverter and battery sizing to power my camper microwave

I would argue there is less potential.

The 100ah Battleborn (BB) battery cost more for a very good reason---better redundancy. BB uses 100+ cylindrical cells spot-welded in a parallel/series configuration (vs. series connected prismatic cells). Configured this way, a few cells can loose capacity or become unbalanced and have very little effect on the battery's overall output.

99% of the 100ah lifepo4 batteries on Amazon, etc., use prismatic cells. Typically 4 in series. If *any* of these 4 cells loose capacity or become unbalanced it directly and immediately degrades the overall output of the battery---potentially to the point the battery becomes almost unusable, all because of one cell.

BB could have easily chosen to use less expensive prismatic cells, but they didn't in order to provide a more stable, robust battery.

No, they’re still overpriced thanks to a following due to being the first legit LFP guys.
But hats off to them. I never turn down selling something for 2x what it’s worth if someone will pay me for it. And continue to do so until I can’t.

There's always a different opinion. I don't subscribe to the 'overpriced' argument.

I always buy the best I can afford, and if you plan on RVing for many more years, I would buy the BBs.

It's not that cheaper products won't work, it's for how *long* they will work. My life experience is 'you get what you pay for.'.. every time.

battleborn is way over priced for what it is. the componants are being used by other as 1/2 the price and with a different formfactor (ie prismatic instead of round battery cells, even less while the technology and quality remains the same. I would argue there is more potential for something to go wring in a battle born with over 100 cells soldered in as aposed to a prismatic type with only 8 battery conections, but it will be easier to detect on the prismatic. when battle born came out they were almost the only player so they could set there pricing where they wanted.. now they have failed to drop there pricing to reflect current componant pricing so other have filled that space with quality products. what did battle born do, they launched dragonfly there OEM division for rv shops and such so they can charge 3800 cdn plus taxes for a 270AH battery. no thanks concidering I built my first 280AH battery for under 700 bucks. saving 3000 is worth learning how to do it to me haha

here is a good video from will about the 3 cheepest good quality batteries and he even mentions ones not to buy.

Buy 2, 100 ah SOK batteries....I am not looking for the cheapest, I am looking for the safest, most reliable approach.

Is there some reason you chose the SOK rather than say, Battleborn?

I have seeing some really positive stuff about Battle Born…… agreed or not?

Price would be much cheaper for SOK

Yes, which is why I quoted what he said about cheap.

2oldman,

Price would be much cheaper for SOK

My approach is to buy good stuff from the start because there’s not much economy in having to do a repurchase…
