B100 Battery Pack for S3 Pro Replacement 10000mAh Hot-Swap Battery Accessories, Magnetic Connectors

Pros: • Longer VR sessions made easy. The B100 delivers up to 3–4 hours of extra playtime per pack, letting you swap batteries mid-session for uninterrupted immersion.  • More capacity, minimal extra weight. Compared to the older B2 pack, this one nearly doubles capacity (10000 mAh vs. 5200 mAh) while adding just ~28% more weight.  • Smart and safe design. With high-precision Texas Instruments BMS chips, it offers accurate battery-level readings (1–100% via 4 LEDs), plus built-in temperature sensors and protection features for both performance and safety.  • Efficient power and heat management. The updated high-voltage design improves energy conversion, delivers higher output, and reduces overall heat compared to prior generation packs.  Cons: • Compatibility limitations. It’s only compatible with the S3 Pro strap (and not with older M1/M2/M3 series headbands unless using the separate B100U upgrade kit).  Verdict: If you’re using the S3 Pro with your Quest 3, this battery pack is a no-brainer—offering significantly more playtime, smart safety features, and minimal added weight. It’s a truly essential accessory for longer VR sessions without the hassle of charging downtime.

An extra battery pack is a must! Charge it while playing and you'll have unlimited play time. It's super easy to attach and detach. When it's on the charger, it will show the progress so you know when it's almost done. And if it's done charging and still attached to the charger, the lights will shut off.

Lasted 13 months and died, won't charge, won't light up... Glad I didn't get the 1 year protection plan with it... What a scam... BOBOVR's customer service asked I send them pictures of the battery's model/serial number and then sent me a new one. Great customer support!

Absolutely fantastic product, its ability to charge the Oculus Quest 3 utilizing Quest Games Optimizer for many HOURS, while having a second one on the charging dock really does allow for all day gameplay. I've done it, it just works. There's no doubt in my mind or anyone else's mind who gets an S3 head strap to purchase this along with the charger for it. The design is also futuristic looking which I think looks awesome on the Quest 3. It has a magnetic base on the back, so when you're using the Quest 3 in passthrough mode to look for the battery pack and put it on, it's essentially no fuss. It just fits right in and you're ready to get going again as soon as you hear the "beep". Can't recommend enough for a Quest 3 owner with the S3 head strap.

Charges quicky than they headset dies while gaming. Batteries lasted a year without issue thus far

Great battery life! Keeps me in Vrchat on my Quest 3 much longer! Real easy to swap out while still in game. I've got three of these and the charger that chargers three at a time. Made of sturdy plastic, but try not to drop them, or any battery. Especially didn't drop these on your keyboard, unless you wanna buy a new one as these are quite tough!

Best batterries. And works great to charge your phones. Not sure about longevity but as of now, I can say all batteries should work this way. Amazing to put batteries on headset without needing to take it off. Slips into magnetic place perfectly every time. And the chargers for these work 💯 as well.

I've purchased so many batteries and chargers from this brand. One of my batteries completely stopped charging. I still had a manufacturer warranty with the company. I contacted BOBOVR and let them know the charger is working fine. All of my other batteries are charging fine. There's only one battery that won't charge. They responded with: "Hi Check for any fault codes (Tested completely according to the video in the attachment) : Connect the B100 to the charger and charging cable, and then place it on the S3 Pro/E3Pro. After the display screen turns off, click the scroll wheel button once and observe whether there will be a fault code prompt on the display screen (please note that the connection cable of the S3 Pro/E3Pro does not need to be connected to the Quest at this time). Please provide a video of the operation, a clear back photo of the battery and your order PDF invoice." Are you kidding me? I have to jump through hoops AND make a video of it? That was my last purchase from this brand. They lost a good customer because I have so many more vr batteries, chargers and meta quest 3 accessories I'll be ordering in the future.

Better than the Quest 3's built in battery, that's for sure. I have 4 of these now. The 2 that came with my 2 S3 straps and I bought 2 of these here as spares. Kind of necessary if you own an S3 strap. lol I mean no other battery will fit the S3. Thankfully though these happen to be a pretty damn good battery. Adds hours of play time to your Quest 3. If you do short play sessions around 2 to 4 hours, a single battery might be enough, but if you plan on playing all day long and want to be untethered, you're gonna want to grab some of these. Only complaint is they're a bit pricey compared to similarly rated USB power banks. But seeing as they're designed for a specific strap in a currently very niche market, that's to be expected. (I have Romoss power banks that last longer and cost less, but they don't fit on an S3 strap now do they? lol) Thankfully they do seem to be well made and feel like a premium product. If you have more than 2 of these you may want to also get a BOBOVR BD3 charging dock also.

Does the job! Keeps the Quest 3 running much longer than without so if you are looking for extending the battery life significantly I highly recommend buying 2 of these to quick swap during longer sessions.

Ok

amazing :o
