- Choosing the right RV battery. Todd discusses one of the most important components of an RV's electrical system. www.bigbeardba...
With so many different types of batteries available, it can be overwhelming to choose the right one for your RV needs.
Todd breaks down the different types of batteries commonly used in RVs, including lead-acid, lithium-ion, and AGM batteries, and compares their advantages and disadvantages.

We got our RV a few years ago. We go camping leaving all the high tech gear behind. I looked at the cost of going with the lithium batteries and the different changes we'd have to make to the charging system. It was cheaper for us to replace the lead acid batteries every four years and charge them with our 100w solar during the day and if need be use our generator when needed. We've traveled the country and this has worked well for us. Until the lithium batteries mature enough it doesn't make sense for us to switch.
Nice summary, and i've heard good things about this brand. One nit-pic - if you are gong to talk battery tech, please distinguish between cells and batteries.
Hi, I am in the process of changing my fifth wheel to Lithium Batteries and am curious what I need to do to my 2019 F350 Ford Super Duty, to protect the alternator. Thank You
So here's my question amd hopefully you'll answer this... WWE have a 2018 Coleman Lantern 273BH... If I add solar panels, a controller, a lithium battery or two... do I need to switch the converter out or can I keep the converter and add an inverter in the loop?
Hello Todd - love your Tech Tips. I am interested in adding lithium batteries and an inverter to my 2023 Coachman Freedom Express 252rbs. I would like to be able to use the outlets in the rig when not hooked to shore power, thus the inverter. The size of the inverter I would like to install is a 3K watt pure sine wave unit. I'm planning on 400 amp hours of battery power to run the inverter. I will not be using the set-up to run the AC - only a coffee maker, microwave, maybe the TV or DVD on occasion. I have calculated the draw, and I think I am well within the 3K watt parameters.
My question is this = Why do so many set-ups use 4 100ah batteries wired together rather than one 400ah battery? It seems to me that the extra wires, BMS systems, leveling issues with chargers would be eliminated with just one battery, with one BMS, and just one wire to the inverter.
My second linked question - is there an advantage to 4 100ah batteries that supersedes the use of only one 400ah battery?
Thanks for your help!

I asked myself the same thing. I think it was simply because of the cost of batteries when they fist came out and limited knowledge of the end user. it was easier to sell a "direct swap" application. THis is why I started Big Beard Battery to offer a 300ah battery.
Todd, you are confused about power and energy units and terminology. There is no such thing as a "watt per hour." A watt is a unit of power (you can divide by 746 and get horsepower) or a rate of energy usage, so it already has a time component. Amp-hours times volts gives you watt-hours. Watt-hours is a unit of energy. Multiply by 3600 and you get watt-seconds which is joules. Watt-hours is a useful number number because it gives you an idea of how much total energy the battery can provide before it dies (keeping in mind the 50% vs. 90% drain thing). Now if you know the wattage of whatever you're powering, you have an estimate of how long it will last before recharging. If you have a 1200 watt-hour battery, you can run a 600 watt appliance for an hour (or a 100 watt appliance for 6 hours) before draining it 50%.
Todd how many barriers ( lithium ) do I need with 200 watt solar panel
Todd I have 200 watt panel on rv, how many lithium batteries do I need.
It's Todd Rawls! 😆
Easy…Lead acid, AGM or Lithium! Just tell us!
Lithium is the best for a parallel set up.
There is no single best! True in anything.
Good God, get to the point!
