Along with its line-up of high-capacity modular power stations, Bluetti has got some impressive external batteries. The B230 and B300 are the two models that work with most of its big-size power stations to add extra storage capacity to them.
The B300S is a brand-new model that Bluetti launched with its new AC500. Here is our detailed take on Bluetti B230, B300, and B300S battery modules.
These extra battery modules are basically designed for additional storage, they themselves carry several charging outlets, including a 500W AC socket. The B300 has got a 200W MPPT controller to let you directly charge from the sun and the B300S has got a 500W solar input and it is a self-heating battery pack.
Bluetti introduced these battery packs with the launch of AC200 Max and AC300. However, thanks to a convertible cable and a DC Enhancer D050S, the battery modules are compatible with almost all the brand’s large power stations, including EP500, AC200, AC200P, EB150, and EB240. The B300S was unveiled with the brand’s AC500.
With the DC Enhancer, you can charge these battery packs directly from a 500W solar source via its AC input. That said, you can attach B300 with an overall solar output of up to 700 watts along with its built-in solar charging input. Meanwhile, the B300S can accept up to 1000 watts of power with solar and AC inputs.
| B300S Official Release Update: Bluetti is all set to launch its AC500+B300S extra battery on November 24th, 2022 for the Black Friday sale on its official website for a price starting at $4499 (the bundle). The separate price of B300S will be available on the link below.
B300S Release Update: Bluetti unveiled AC500 with the extra battery B300S on September 1, 2022. The B300S battery has an early bird price starting at $1799 without the inverter station. AC500+B300S Combo Price Update: Weeks before the Indiegogo release, Bluetti made a surprise announcement of the early bird prices of AC500 and B300S kits for limited buyers. The combo of AC500+B300S will be on sale at $2999 (38% off of its MSRP of $4799), and the AC500+2*B300S combo will cost $4699 (36% off of its MSRP of $7297.) The exact release date is not yet unveiled, which will take place in September 2022, though. Update: Bluetti launched a new B300S extra battery to accompany its massive AC500 power station. It is also a 3072Wh battery pack but with an improved 500W solar input and a combo charging of 1000 watts. |

Bluetti B230, B300, and B300S Expansion Battery Modules
Bluetti B230, B300, and B300S are simply three extra batteries. You can quickly attach them to nearly all of Bluett’s power stations for additional storage. It will be quite nice to get one or multiple units of the battery modules stacked upon those machines for seamless off-grid power in the wild.
Well, B300 is a special make for AC300, which comes up with no battery inside and the extra battery is the only way to add storage capacity to it. Anyway, here, we would like to have a look at the specs and features of the famous Bluetti expansion modules.
Bluetti B230 Expansion Battery Module
As you know, this is the smaller variant of the duo. It equips a 2048Wh LifePO4 battery pack with an individual AC input of 500 watts. It has got no solar charging option, but you have it with multiple charging options.
They are single pieces of a Type-C USB 3.0 100W Power Delivery port, a USB 3.0 Quick Charge 18W port, and a 12V/10A carport. Even without connecting it to a power station, it can power up your essential USB and DC devices.
As said above, Bluetti B230 hit the stores along with the brand’s AC200 Max. At its debut, it was only available in bundles with the modular power station. But from Sep. 2021, it will be available individually and so users of the AC200 and AC200P can also grab it for adding up power to their devices.
As you see, it is a highly compact and ultra-portable battery. You can easily take it on its built-in carry handles and enjoy access to unlimited portable power. It has a size of 16.5 x 8.9 x 11 in and a weight of 48 lbs.
Its retail price is $1699 and you will get it at $1199 at debut.
Bluetti B300 Expansion Battery Module
It is a bigger capacity extra battery module from Bluetti.
B300 equips a 3072Wh LifePO4 battery pack and it will be launched with the brand’s AC300 in September 2021. It is also compatible with most of the brand’s other power stations, including AC200 Max.
With an extra storage capacity, it is indeed a more reliable way for off-grid users and emergency preppers. Other than the 500W AC input, it has also got a solar input, as stated above.
That is a 200W individual solar inlet with an MPPT controller. So, you can have a total input power of 700 watts along with the AC input. For charging ports, it has the same units as its younger variant, B230.
Bluetti B300 has a size of 20.5 x 10.4 x 12.6 in and it weighs 74 lbs. It is also compatible with the company’s special DC Enhancer, so users of old-gen Bluetti power stations will be lucky to get a more powerful extra battery with individual solar and AC charging options.
It has a retail price of $2099 and will be available to you at a debut price of $1599.
Bluetti B230 Vs B300 Vs B300S – What to Buy?
It is all about the battery capacities of the three Bluetti battery modules. You have three extra battery modules with the same compatibility features. The most recent B300S is the most advanced one with its self-heating feature and a faster solar charging input.
Using the brand’s convertible cable, you can connect single pieces of the batteries to AC200 and AC200P through their solar input ports. The cable is free for Bluetti customers!!!.
If you want to connect over one unit or to use them with the old-generation Bluetti power stations, you can get the special DC Enhancer.
Coming to availability, the battery modules are available individually and in bundles with various compatible power stations on the Bluetti website. We have the links to buy the battery packs above with quick glances at their specs.
Final Thoughts
That has been our take on the Bluetti B230, B300, and B300S expansion battery modules. We have checked out all the specs and features of the innovative extra battery modules. We will keep this article updated when the new model B301 hits the stores. Most likely, the B301 and AC500 will arrive on the market by late 2022.

Do we know why the new AC500 only supports 4 X B300 batteries yet can do 6 X B300S batteries? Looks like the batteries only differ by the charging capability (input power capacity).
I bypassed the AC300 and went with AC200MAX + 2 X B300 batts last year because I did not like the idea of the AC300 not having an internal battery and still wanted something in the 2 kW range
and one brick to take remote with me if I wanted. The expandability of AC200MAX still lets it stretch to a home back up solution from a capacity standpoint too.
This bigger AC500 looks more like it though for home based back up. 5kW continuous will go a lot further than 3 kW. They should have started this line with the AC500.
