Yes they do. Ever since the brushless line came out they've included those pins. I haven't popped open a ryobi battery, but those pins can't just be to supply more voltage. Batteries are either in a series or in a parallel... 18 volt would be the max on these tools. According to ryobi that allows the brushless to communicate with the batteries controller on how much output to use.

Lithion ion batteries aren't the most stable - it's not just xx batteries put together to work.. These batteries need a BMs manager, if they discharge at different rates, overheat, or pull too much draw at once they can start fire or explode (I build ebike kits out of these, they're very finicky).

What you're doing MAY be fine... But from what information I've found out online it's a bad idea and can wreck your tools.and batteries. Especially if you're charging them in the non-matched charger.

Ryobi and ridgid are made by the same company pretty much.... So you have that going for you. But even though it's a small chance, I wouldn't want to risk a fire to save a few bucks. At the very least you should tell people not to put the adapters in the chargers.... That's where the fire would likely start. Here's an excerpt from something I found online with Milwaukee tools and adapters - and again... I'm not a battery expert. I've just seen a few fires (caused by me!) from these 1850 batteries. They're great batteries, but there's a reason they're not replacing as batteries...

" If you take apart either of these batteries and tools you will notice each of them has a circuit board close to the terminals. This is for the battery and the tool to communicate back and forth so it can get the most from the battery. This protects the tool and battery from failure due to overheating or overload, (When the tool shuts off automatically until it cools down) To add to that, the circuits in the batteries communicate with the circuits in the chargers to optimize the charging time of the batteries. Tools have come a long way, but the general consumer/public knowledge of their internals have not. If you use an adapter to connect one of these batteries to a tool from a different brand the LiON batteries will discharge their maximum capacity, instead of rationing it to optimize the performance. In short, you will have the ability to supply power to the tool, but it will only be able to discharge at the battery’s maximum rate. Meaning that you will get much shorter run times, the battery could potentially overheat, and the tool could suffer failure, especially if it is not brushles"

Get a volt meter on those two rear pins, 99% sure it'll read 18-20 volts, they're additional voltage pins, nothing more. The front pins are for the charger.
There's no communication between a tool and battery, dont be fooled by marketing speak, my brushless ridgid tools have only two pins, you can't communicate over two pins. When the battery overheats it'll stop, when the tool overheats it'll release the magic smoke and die even with an original battery.

The ryobi/ridgid batteries have bms's on them, its to protect it from everything you just said.

Nowhere did i mention you can charge through the adapter, in fact if you plug it into a charger it simply won't charge, the temp sensor pins aren't connected let alone probably output different readings.

Again the bms on the battery will prevent the battery from going boom. The bms has discharge current protection, over/undervolt protection, temperature protection, it balances cells when charging and many other fail safes so the battery doesn't pop.

Again you can't communicate over positive/negative pins, its marketing jargon. While charging there is communication over the temp sensor/diagnostic pins but that's it, not when actually using the tool. Don't just say they communicate, prove it, show me where and how the communication happens between the tool and battery and i'll eat my words.

The octane Ridgid tools have 2 extra pins for communication on the side of the connector. Doesn't matters anyway because they aren't required for operation.

Hi there - sorry - first time poster - I signed up specifically to reach out about the adapter, but can't see how to PM you. I'd like to purchase 2 and live in GTA.

How easy is this to take on and off the ridgid battery? Do you have to screw into or damage the ridgid battery in any way?

Good day,

Are you planning to make more ? I would be looking to possibly get 2 of them shipped to Kingston if that's possible.
Can't seem to be able to send you a pm, but might be because I'm on mobile browser

Thanks !

I'm interested in 2 of these delivered to area code 17013. What would the cost be delivered? Also do we know if these would work with the Ryobi lawnmower.

I dont recommend using them is a lawn mower, even stock batteries get overheated/burned in them. Im waiting for parts before making more.
