Battery choice - guidance requested

So I have a small travel trailer with limited space for a battery. Have a Victron Solar controller and SmartShunt but looking for a better capacity battery than the cheap one that it came with. Draw is a handful of LED lights, USB ports etc - no need for large current draw but capacity and lifespan are king

The current battery box is 280x175x244mm so want to look for something that sits inside the same footprint

I am looking at the BAT412110081 AGM Super Cycle or the BAT412600104 Deep Cycle Gel as the two that will fit.

Which would people recommend as the better choice and which has the larger capacity?

Thanks in advance for the help!

Hello ttttfrosen, in the first line you answer your question already. You have to go for lithium !

Lithium takes approximately 60% less space then an AGM or GEL.
Also far less weight and far more easy to charge and discharge. This all will benefit you well on the long run. You can have long travels and enjoy your energy.

Best regards, Rob

Rob - thanks for the answer but the budget nor the amount of usage extends to justify lithium at this point - nice but too expensive being at least 5x the price of the two choices


hence the question of AGM vs Gel
