NEW! 270Ah Battle Born Lithium Batteries

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.

BBGC3 VS BB8D

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 EXPLORIST.life. 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.

Hi Nate:

I'm looking to utilize both 12 and 24 volt components/appliances in my build. I plan on wiring two 12v (BB GC3's) batteries in series, plus use a 24v inverter/charger with a separate 24v to 12v step-down component, and want to know:

1. How to modify or best use your power audit spreadsheet to more accurately estimate power consumption for 24v items? 2. It seems that amperage draw using 24 volt items (such as a refrigerator) could be more than twice as efficient as 12v; i.e. less than half the amp draw. If correct, would recharge rate @ 24v; whether from shore power or solar, be equally efficient; i.e. better than half the time?

Thanks.

Can you stand these up Vertically in a rack? I ask cause I have plenty of vertical space/height to spare in my "garage" area.

Nate - thank you so much for your helpful videos and information. I have 3 BCG3 batteries coming and will connect them to the Victron Power in. I have a 3' run from the battery to the power in, what cable size should I use?

Hello Nate, I'm planning on moving to Lithium and had some questions on two of your diagrams. Figure you are editing them as time and changes permit so here goes.

In looking at your 50A and 30A Camper-Inverter W/Solar & Alternator Charging, you show a MultiPlus in the 30A with the converter disconected and a Magnum MSH for the 50A with the converter status unmarked. I just bought and installed a new PD4645V with Lithium capabilities in my 2000 Lazy Daze (30A) so I'd like to NOT waste that purchase but I do want to enjoy all the benefits of the 30A diagram. Any help or am I just stuck with a new converter?

Thanks, Don

I've got three GC3's that I am about to install into my new van. The terminals on them are only about 4" apart the way I have them lined up next to each other. Instead of using 4/0 cables between them, I was looking for alternative ways to hook them up and came across your "Battery Interconnect Bar for Battle Born Batteries" [https://www.explorist.life/shop/all-products/battery-interconnect-bar-for-battle-born-batteries/]. They are currently out of stock, and I'm not sure that they are the right length for the GC3 anyway. Do you plan on restocking these to connect multiple GC3? Thanks
