2 Packs 40V Lithium-ion Battery OP4060 6000mAh Compatible for Ryobi 40V Power Tools OP4040 OP4026 OP4030 OP4050 OP4060A High Capacity Removable Rechargeable

I bought this little battery to run my VEVOR 8kw diesel heater. I typically run the heater for five to six hours at a time, and this battery is perfect. Starts the unit from cold up to running temperature and can handle low and high speed. The battery is lightweight and appears to be well-made! Very happy with the purchase.

Very impressive I have a 36 volt 112lb Thrust Minn Kota Ulterra and went out to the water twice with heavy current and used it 8hrs with no issues. I wanted to try it to give my honest feedback. They take up little space and I can pick each one up with my pinky they . My other batteries was 75lbs .

What a great replacement battery for my ring cameras! Works perfectly, love the additional charger stand.

Shipped quickly and is just as advertised. I think it will be great for my needs.

Really good quality batteries.. works well with my cell camera

So far so good. No complaints, used one battery to install 16 wheels (96 lug nuts) and battery was still showing full. Didn't catch fire on the charger either..that's a plus. Would recommend.

Great attachment will recommend to anybody with Milwaukee tools Creates power

Si son compatibles con la marca roja y son muy exelentes funcionan ah la perfección

Battery is very Iight. Couldn't belive how much smaller it is compared to a 12volt battery.

Powers my livescope perfectly! Hopefully all day if needed
