Web2. NeckSnatcher • 3 yr. ago. So just to make sure I'm understanding correctly, let's say I have 2 100Ah lithium batteries connected in parallel each with their own BMS, each rated for a max discharge current of 100A. When in parallel would this max discharge current be doubled, giving me up to 200A to work with for short bursts for my ~120A ... Web8 de dez. de 2016 · In simple terms, a battery’s autonomy depends on the load it must support and its amp-hour (Ah) rating. For example, a battery system rated at 30 Ah could in theory support a load of 30 A for one hour. But it’s a little more complicated than that. In reality, a VRLA lead-acid battery’s Ah rating isn’t fixed, but depends partially on the ...
