Hi From UK

Hi, Im in UK, Looking for advice to build an RV battery. Im a dog handler and my truck runs a RV type battery to operate heating/cooling/control systems for my dog crates.
It charges from vehicle charge system and backs up with a solar panel and Victron bluetoothcharge controller. My RV battery has died for the second time and Im bored of lead acid batteries now.
Ive got quite a bit of space, weight is not a massive issue, so thought Id look at building a 12v battery pack to run my onboard system for the dogs.

Hi and welcome!

First of all you need to understand why your current batteries died. Did it die because you cycled them to hard? Or of age and no missuse?
Most of the times there is to little capacity and you cycle them way to hard and this kills of any batteries way fast. Even Lithium will die fast if you do that.

Lithium is alot lighter so thats not a problem If you think of 12V only I highly recommend 12V LiFe packs. They will fit very nicely but cost a bit more. They are ALOT safer and will withstand alot more cycles. but they also cost more.

Welcome! I'm buying a 5th wheel RV in the spring so I'll be doing something similar. Either going to stick with 12V or upgrade to 24V and get a 3000W inverter. Should be fun. Enjoy!

That'll do it. Lead Acid can only go down to 50% of max capacity or they take damage.

Your quote is all messed up. Looks like you type in the box and not underneath it.
