Dual Purpose Batteries LiFeP04 are quickly becoming a popular item that many enthusiasts demand.

(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 molded, heavy duty, re-closable 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 molded into the side corners helping to keep your straps seated securely in place.

Large heavy duty battery terminals ensuring there is no heat buildup 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 principle that we have inherited from many generations of Anabaptist forefathers. We pledge to always put the customer and his needs first.

AMAZING!
Color: Pink Blue
I have never written a review before, and I shop 4-5 days a week on Amazon. My 5 month old puppy LOVES these chew toys. When I first opened the box I was worried because they were so hard, but Poppy went crazy. He chews on them, tosses them and retrieves them, runs in circles around them and barks, and when he finally settles down will chew them and make these pig snort sounds of contentment. I have bought a lot of toys for my new puppy… But these are the best by far!

Toy broke in two
Color: Blue
This is a great toy for aggressive chewers. My reason for 3 stars is my dog dropped it on the tile floor the second day she had it and it broke in two. Not real happy with that. Update: The seller has been proactive and accepting of the very minor issue of the toy breaking. Responded within 24 hours and issued a refund. Because of their response I am changing my review to 4 stars.
