Aolithium 100Ah lithium is the perfect in-between for those who want high-capacity lithium in a small physical size and economical price tag. At only 12inch in length, this battery gives unprecedented fitment flexibility of over 1.2KWh of energy. Perfect for marine, camping and conversions, and is the equivalent of a whopping 284Ah lead-acid battery.This battery is 7.4inch high, so it will fit under seats.This battery is also perfect for those who need a 12V power source in a condensed and lightweight package.
Despite its high initial cost, Aolithium is cheaper than its lead-acid counter parts over its lifespan. Our design life is 10 years - rounded up this battery costs £77 a year. The closest capacity equivalent in lead-acid is the Exide AGM EP1200 with a design life of 4 years - currently around £88 a year (replacing the battery at the 4 year mark). This equates to over £110 in savings, plus all the benefits of a lighter, smaller and more efficient battery.
While the design life of AoLithium is 10 years, we expect the average user to reach 15-20 years, making it an even better investment. The realistic average life of Lead-acid is 3-5 years.
The same capacity in a single lead-acid battery weighs a massive 90lb (Exide AGM EP1200), and is over twice the physical size. A 67lb weight saving can mean a huge difference when traveling abroad, as well as offering better MPG on vehicles.

12 volt 100ah 4s battery

order received quickly, only completed 1 cycle so far but impressive.

Mark Walker
Fantastic battery

I received my batteries within days of order, very well packaged and transported for free and they are phenomenal.
I'm new to lithium leisure batteries so I have nothing to compare them to. Other than lead. Which brings me to the point - They charge up from 10% to 100% in about FOUR hours! Woo hoo

George Aitken
Quality product, quick delivery

Order the Aolithium battery on 13 December 2023, Battery arrived 18 December 2023, delivery updates were few and far between, but battery appears to be of good quality and is working well, the app is not very good and could do with some improvement, overall very happy with this purchase, would buy from aolithium again.

David Kilgariff
Great battery

Purchased this 100ap battery , wasn’t sure what to expect, got the email saying on its way , few days went past nothing , seriously thought I’d been scammed, but it turned up well boxed , in absolute perfect condition, charged it on my new Victron 30 amp charger under 2 hours , very good battery so far .
