NEW! 270Ah Battle Born Lithium Batteries

Battle Born just released their newest batteries to their family of LiFePO4 Batteries. We have all been asking them for a few years at this point to release a battery larger than 100 amp hours, and they’ve answered in a big way with two different 270Ah batteries coming in two different form factors.

Battle Born BBGC3 270 Amp Hour Lithium Battery

The Battle Born BBGC3 is a 12V, 270Ah LiFePO4 Battery with an internal BMS. It doesn’t look like any other battery on the market that I’ve ever seen so it’s sure to turn some heads but more importantly… like all of the other Battle Born lithium batteries, it’s a drop-in battery, which means that it is designed to be a stand alone source of power storage with no need for an external BMS.

This battery is 22.83″ long x 7.09″ wide x 13.15″ tall for 270Ah of power as compared to their 100Ah Battery, which is 12.75″ long x 6.875″ wide x 9″ tall. This means that you can get 1.4 times the power in nearly the same footprint if you can spare the extra 4″ of battery height for the BBGC3.

Battle Born BB8D Amp Hour Lithium Battery

This battery looks like and has the same dimensions as the standard 8D battery that is common in many OEM RV’s, but that’s where the similarities stop. This battery, like all of the other Battle Born batteries, is a drop-in replacement LiFePO4 Battery complete with an internal BMS.

This battery has a larger foot print than 2x 100Ah Battle Born Lithium Batteries, but is about an inch shorter and has an extra 70Ah of battery capacity.

The BBGC3 and the BB8D are pretty much the same battery in everything other than their physical shape. They charge & discharge at the same rates. They have the same BMS parameters. They can both be wired into (up-to) a 48V battery bank. They have the same amp-hour capacity. They have the same 10-year warranty.

So, which one is best for your needs? I highly suspect that the BBGC3 will be better for the camper van crowd as van electrical installs are usually more ‘vertical’ and the tall/slim nature of the BBGC3 will likely work better in that regard.

The BB8D will 100% be better for those OEM RV’s that have a factory installed 8D sized battery installed as the factory house battery.

Ultimately, though… you’ll just have to break out the tape measure, some elbow grease, and some CAD (Cardboard Aided Design) to see which size of battery will work best in YOUR space.

Old vs New – Battle Born Batteries

The Original 100Ah Battle Born Batteries are still wonderfully awesome batteries and I will very much continue to recommend them here on The smaller size gives a bit more flexibility in where/how you can configure your battery bank. Ultimately, though, it’s REALLY nice to have options at this point.

The main draw to the bigger battery banks is that you can pack more power into a smaller space and will rely on fewer battery-to-battery connections to make a large battery bank. This means less wiring and a more balanced discharge from the battery bank.

How to Wire a Solar Charge Controller for a DIY Camper Electrical System
How to Program a Solar Charge Controller

Are there any special challenges to building a 48V system?


Saturday 24th of April 2021

I'm converting a 20' box truck into an RV that I want to live in full-time, so I want some powerful batteries and solar. I'm a novice at this, and I haven't found the exact kinds of information I need to make a decision on the batteries I'll want.

I have 8 415W LG solar panels (though I may end up only using 4, depending on how heavy the 2 tier rail system I'm designing gets), like the ones listed here

I want to store energy with about 4 used tesla model S lithium ion batteries, as sold here:

It naively seems to me that this would work fine. But I'm concerned that I'm missing something obvious. Is there something I'm missing or that I should be looking out for?

Thank you!

With the proper BMS for the Tesla batteries and solar charge controller for the panels... those panels would indeed charge those batteries.

Nate, All new to me but sounds like the GameChanger will be a GameChanger!

Im setting up a 600Watt solar on my 23ft airstream would it be better to run just 1 of the 270 or three of the 100? Pros cons to both I have an area around 11 inches wide by 5ft long to set up for all my solar stuff invertor, controller battery's ect. Thanks

Nate, Im accumulating parts for a 300a solar/200ah battery system for a new Transit that's arriving next month. However, the van is also coming with dual AGM batteries, and what I can't figure is how to incorporate one of these batteries in my total house system, so I'm not just packing around an extra battery that otherwise is pretty much never used. Thanks for your help Kevin
