Although I'm familiar with TCW primarily with a backup battery, they make a lot of innovative products for experimental aircraft.
Take a look at their web site if you get a chance: https://www.tcwtech.com/?v=7516fd43adaa

But the best thing about TCW might be Bob Newman. Always available and always helpful. He makes it a pleasure to do business with the company.
He owns a RV8 and a RV10, and is building a RV14A. So he definitely knows RVs.

Another +1 for Bob and TCW Technologies. I had a 28v voltage conditioner go bad and Bob flew a new one down to me in his RV10. Great customer service and products.
