Renogy BT-2 Bluetooth Solar Module

I had trouble finding the proper charger with the right connection. I don't like multiple connections using adapters. I think it's a problem waiting to happen. I found your site and was very pleased to see the correct charger and connection there and reasonably priced. I haven't used it yet but I'm sure it will work just fine.
Thanks

I’ve been using the 48V 12.6Ah battery for my daily commute, and it’s been flawless. Acceleration is strong, and I get consistent power all the way through the ride. The build is solid and fits perfectly in my setup. Charging is quick, and I haven’t noticed any performance drop even on longer trips. It’s clear this battery was engineered with quality in mind.

I’m not a tech guy, but setup was super easy. The app made it simple to monitor things, and the battery delivers strong, stable power for all my gear. Worth every dollar.

I Installed two of these in my off-grid cabin. They’ve been consistent through heat and cold, and the Bluetooth app lets me keep an eye on everything remotely. Great Canadian product—no complaints.

This battery completely upgraded my e-bike experience. The 48V 16.8Ah pack gives me noticeably extended range and solid performance on every ride. No voltage sag, and it handles hills like a champ. Build feels premium, and installation was simple. I’ve put it through some demanding routes, and it’s never let me down. Easily one of the best long-range packs I’ve used!

I’ve been using this battery in my off-grid solar system for a few weeks now and it’s exceeded expectations. The Bluetooth monitoring app is accurate and super easy to use. I can check the state of charge, voltage, and health right from my phone. Great build quality, runs cool, and the performance is rock solid. You can tell it's made by real engineers.

I’ve used TYS batteries before and this one is just as solid. High discharge rate, runs cool, and lasts long. Perfect for my backup power system. Feels like a premium product.

Switched from AGM to this lithium unit and I’m blown away. It’s lighter, charges faster, and gives me better usable capacity. Plus, the Bluetooth monitoring is a total game-changer.

I always try to buy Canadian when I can, and this battery didn’t disappoint. Fantastic cycle life, safe operation, and I love knowing I’m supporting local innovation. Highly recommend.

Super happy with the ST3 charger—sleek design, clear LED status, and a snug connection every time. Charges efficiently without heating up, and feels way more solid than cheaper alternatives. A perfect match for my TYS Energy battery. Great value for the quality!

This battery completely transformed my e-bike. It delivers consistent power even on hills, and I’ve noticed better acceleration and overall ride quality. The build is solid and sleek, and it fits perfectly in my setup. Charging is quick, and it holds its charge like a champ. TYS really nailed it with this one—top-tier performance at a fair price.

I use my e-bike to commute to work every day, and this battery has never let me down. Charges fast, lasts long, and keeps me moving without stress. Feels like a huge upgrade from my old battery.

Swapped this in for my aging pack and noticed the difference immediately. More torque, more speed, and no overheating on long rides. Very impressed with the quality.

Great charger! Compact and easy to carry in my backpack. Charges my 48V battery efficiently, and the LED indicator is super helpful. Feels durable and well-made.

You can feel the difference in craftsmanship. It’s solid, charges quickly, and gives me excellent range. Great investment if you ride often or rely on your e-bike for transport.
