Information 

Built to Run All Day. Built to Stay Out Longer. 
 
Most 36V systems on the market are built to hit a price point—not to perform. This battery was engineered for consistent, reliable all-day power without drop-off or failure. 
 
Not another weak “Amazon battery.” Most lithium batteries are underbuilt and designed for light use. MillerTech batteries are intentionally over-engineered for heavy draw, long runtime, and real-world outdoor environments. 
 
Overbuilt Where It Matters: 
– Advanced BMS Protection 
– Custom Waterproof Case 
– Dual Stainless Steel Breathable Air Vents 
– Pure Brass Terminals 
– Integrated Carry Handle 
 
Engineered for All-Day Performance: 
Install it once. Run it all day. Trust it every time. 
 
Over-Engineered — Without the Overpriced Tag: 
Backed by a true 10-Year No-Questions-Asked Warranty. 

(KEY FEATURES)

10 year Industry Leading Warranty

BCI Group Size 31

Bluetooth activated to connect directly to our MillerTech App. The MillerTech App gives you in depth, real-time data, taking the guessing game completely away. Power with Confidence!

Custom moulded, heavy duty, reclosable battery case. This means if you ever have an issue with your battery no matter is it in year 5 or year 15 we will always have easy access to repair any defective parts. This custom case also has convenient hold down strap grooves moulded into the side corners helping to keep your straps seated securely in place.

Large heavy duty battery terminals ensuring there is no heat build up when your application demands maximum power!

The Sport Series Marine batteries are all sealed with a thick rubber gasket along the lid connection point. This means they are Marine approved IP65 rated. A completely sealed battery case will cause condensation, so we build them with a marine grade Stainless Steel breather vent. Our vent sits on the top of the case unlike some others where the vent sits down inside catching rain and dirt.

A 10 year warranty is not a commitment we take lightly. We believe a warranty is only as good as the company and the people standing behind it. We do realize there is a certain uncertainty about how a company will handle a warranty claim if the need should ever arise. With MillerTech our hope is that the customer will have no doubt in his mind about how we will approach warranty claims. Our company is built on a Golden rule priniciple that we have inherited from many generations of Anabaptist forefathers. We pledge to always put the customer and his needs first.
