>>472050> deep cycle lead acid marine batteries.The general rule of thumb goes;
Car batteries can be discharged 10%
Deep-cycle boat batteries can be discharged 20-25%
AGM batteries can be discharged 50+%
And just as important, AGMs can handle far more charge / recharge cycles and also don't release hydrogen gas (i.e are safe indoors).
> It isn't pure sine wave eitherLike AGM batteries, pure sine wave inverters are the standard nowadays and can be bought for a reasonable price, so if you're putting together any kinda battery power pack or off-the-grid cabin, there's really no reason to go with obsolete tech (which can fuck up some modern electronic gadgets, like flat-screen tvs).
