50ah lithium battery vs 100ah agm

Should a 100 Ah battery be full?

Ideally, you use a bit less than this, but they are quite happy being full, and completely empty, which gives you a massive increase in usable capacity. If you swap a 100aH AGM battery with a 100aH lithium, most people suggest you are getting around 50% extra usable capacity, in conjunction with the 50% less weight.

How much does a 100 Ah battery weigh?

A 100aH lead acid battery will weigh in at around 25kg. A 100ah lithium battery weighs in at around 12kg, or basically half of the weight. However, its far better than just that; the usable capacity of both is vastly different, which also swings in the lithium batteries favour, but we cover that more below.

Are lithium batteries better than AGM batteries?

Lithium batteries, particularly the LiFePO4 variant, boast several advantages over AGM batteries, such as higher energy density, longer lifespan and superior performance. These batteries demonstrate improved efficiency, steady discharge voltage and can be completely discharged without causing harm to the battery.

Are AGM batteries safe?

AGM batteries are generally considered safer regarding thermal runaway and fire risk than lithium batteries. However, both battery types require proper handling, storage, and charging practices to ensure safety. What kills AGM batteries?

How long can a 100 Ah lead acid battery last?

Using this guide, it means for a 100ah lead acid battery, you get about 50ah of usable capacity. In the grand scheme of things the lifespan generally is what falls over first, and you can probably go to 60 or 80% depth of discharge (using 60 – 80% of the 100aH), but its still less than lithium batteries (and most people specify it from a 50% DOD)

What is the difference between AGM and standed lead acid batteries?

While both offer significant advantages over standed lead acid batteries, they differ significantly in their technology, performance and applications. AGM batteries are a type of sealed lead-acid battery, usually used in applications where maintenance-free operation and safety are crucial.
