Modernize Legacy Cordless Equipment and Power Existing Handheld Tools with Advanced Lithium-Ion Cell Technology
The DEWALT DCA2203C 20V to 18V Battery Adapter Combo Kit is an electrical power conversion system engineered to bridge the gap between legacy 18V NiCd cordless tools and modern 20V MAX* slide-style power cells. This high-efficiency adapter kit includes two 2.0Ah lithium-ion batteries and a multi-voltage charger to provide uniform voltage delivery and prolonged runtime parameters across your existing cordless tool fleet. Outfitted with a slimline form factor that preserves original handle balance metrics, this structural charging set allows operators to maintain high site productivity without replacing trusted heavy-duty equipment frames.
Best Used For:
- Legacy Drill Modernization: Converting older 18V pod-style percussion drills and impact drivers to use lightweight sliding lithium-ion packs for structural fastening.
- Extended Reciprocating Saw Runs: Supplying continuous, fade-free electrical currents to legacy wood or metal cutting saws during high-volume jobsite demolition phases.
- Fleet Battery Consolidation: Standardizing diverse jobsite tool setups under a unified premium charging network to eliminate legacy NiCd memory effects and discharge issues.
Key Performance & Safety Features
- Universal Slide-to-Pod Adaptation: Mechanical transition chassis updates baseline terminal configurations to link sliding power packs with vertical internal pod terminals natively.
- Dual Compact 2.0Ah Fuel Cells: Two high-density lithium-ion packs deliver strong watt-hour discharge behaviors while scaling down total physical overhead tool burden.
- Smart System Circuit Protection: Multi-voltage desktop charging cradle automatically tracks state-of-charge limits to prevent thermal degradation and cell imbalance.
- High-Friction Locking Interface: Rigid structural retention clips wedge firmly into the host handle frame to ensure continuous connectivity under severe tool vibration.
- Slimline Geometric Silhouette: Compact housing design maintains traditional tool center-of-gravity placements to counter joint strain during overhead usage.
What's Included
- (1) 18V to 20V MAX* Cordless Power Tool Battery Adapter (DCA1820)
- (2) DCB203 20V MAX* High-Capacity Lithium-Ion Batteries (2.0Ah)
- (1) DCB115 12V MAX* / 20V MAX* Multi-Voltage Lithium-Ion Battery Charger

PRO-TIP: Avoid using high-capacity structural multi-cell or FLEXVOLT batteries inside this system adapter interface. Sticking strictly to compact slide blocks, like the bundled 2.0Ah cells, reduces excessive downward mechanical leverage against the old tool neck and protects the legacy power contacts from structural connection wear.

Fits 1988 Sea Ray V-135 2 stroke (Mercury)
For those of you with the 135 hp
mercury that was branded as the "Sea Ray 135" and paint matched to the boat (i.e. Seville's and some others) this is the 147 degree thermostat for that motor. My Seville is an '88 and It's difficult to cross reference the serial numbers on those motors when searching for parts. Only buy Quicksilver parts for these motors. Happy to find them on Amazon because Boats.net as an example, is not clear on what you're getting.

Not all great stereo systems meet all the requirements for connectivity.
I want to go on record, the Onkyo TX-Nr7100 is an awesome choice for a stereo avr. Great connectivity, a warm sound quality, and many options for your audio sound choices. But, because it's base connectivity, as it applies to Bluetooth, I do not recommend to connecting a PC to it. Due to audio and video, data separation. The Onkyo, though an excellent stereo choice, has problems playing Youtube and other types of media, with built in audio and video playback. It defaults to the miniplayer, built into the system and is impossible to get rid of in these situations. I give this product 5 stars on quality and performance, but it was not made to connect to a computer. Stll, I recommend this AVR Stereo Receiver on its aesthetic look, sound, audio and connections and quality. Very important to keep this in mind for Computer and gaming console connection to this system.

Exceptional Home Theater Receiver with HDMI 2.1, Dirac Live & THX – Incredible Value
After researching extensively and using the TX‑NR7100 firsthand with a 5.1.4 Dolby Atmos setup, I’m thoroughly impressed by its blend of features, performance, and value.
Setup & Interface
The guided setup process is smooth and intuitive—Wi‑Fi setup, firmware updates, speaker configuration and HDMI mapping all work seamlessly. The on-screen menus are clean and accessible, though some deeper options may require a bit of navigation
With six HDMI 2.1 inputs and two HDMI 2.1 outputs, this receiver supports 8K/60Hz and 4K/120Hz video formats, along with VRR, eARC, and ALLM. This makes it ideal for gaming consoles like PS5 and Xbox Series X—performance is solid with no reported signal dropouts on the primary HDMI ports.
Audio & Sound Quality
Every channel delivers up to ~100 W into 8 Ω, powering immersive content such as Dolby Atmos and DTS:X with clarity and presence. THX post-processing adds dimension and scale, especially with cinematic soundtracks. Dirac Live room correction provides musical staging, precise imaging, cleaner dialog, and deeper bass—transformative for untreated or irregular rooms.
Streaming & Multi-Room
Equipped with AirPlay 2, Chromecast, Bluetooth (including aptX), and Sonos/DTS Play-Fi integration, streaming is flexible and robust. Spotify, Tidal, Pandora, TuneIn, and more are all supported. It even functions as a Roon endpoint with no signal issues when streaming high-res audio over Ethernet.
Build & Design
The front panel features a large green display, a straightforward volume dial, and basic controls. While the remote is functional, it isn’t backlit. The control app is usable but somewhat basic, making desktop Dirac calibration a better option for fine-tuning.
Pros:
Cutting-edge HDMI 2.1 support for 8K/60Hz, 4K/120Hz, VRR & eARC
THX Certified with immersive Atmos/DTS:X and IMAX Enhanced support
Powerful and convincing Dirac Live room correction
Versatile streaming ecosystem and smart assistant compatibility
Excellent price-to-performance ratio compared to peers
Cons:
HDMI glitches possible; best addressed via firmware updates and proper setup
Remote is not backlit; app UI is basic
Not truly expandable to 11-channel systems; no independent sub outs or extra preamp channels
Verdict:
The Onkyo TX‑NR7100 strikes a remarkable balance between modern video support, superior immersive audio, and intuitive usability—all at a price point that undercuts many similarly spec’d competitors. If you want future‑proof HDMI features, strong gaming performance, Dirac‑based room tuning, and multi‑room streaming options, this AVR delivers beyond expectation. Highly recommended.

Best deal and beautiful sound
I bought this one on sale to replace my old Pioneer VSX-1120-K 7.2 ch receiver which did not support 4K video and new Atmos sound profile. I would say, it was the best deal in this category since it offered 100 watts/ch , 9.2 ch, 8k/4k supported, and nearly 50% price cut when on sale! The sound quality is amazing, especially after using Dirac live to measure and auto adjust all speakers’ sound curves, making my home theater sound in a different level. The high is very clear but not harsh while the low is soft and nice punch. I also like the Onkyo App which helps to control the receiver in many ways. I can use it together with other online music streaming services app without touching the remote controller any more, very convenient! The only a small problem it has, is that it’s BD/DVD HDMI input sometimes does not work well with Amazon fire stick. It makes the firestick restart over again and again, so I have to use the other input such as game input to work smoothly with the firestick.
Update: I have had this receiver for more than a year now. I would say, I love it more and more! It not only supports 4K/8k video through HDMI, but also has so many listening sound models to choose from, and the App on smartphone is a very convenient tool. One of my favorite functions of it is the Dirac live function. I used to analyze the sound characteristics of each speaker, and fine tune the frequencies on them, making my home theater speakers up to a very high level, making every single sound frequency is in its best condition. This certainly compensates the shortcomings of certain sound frequencies in each speaker. Many times I just sat in my home theater listening to the music from Spotify without watching movie, and it was so joyful. I am changing the rate from 4 stars to five!
