This MillerTech, 4-bank, marine Lithium battery charger was specifically designed for the avid fisherman who only settles for the very best! Our goal, when designing and developing this charger was to create a high-quality, feature-rich, marine battery charger that is reliable and simple to use, making your experience seamless and enjoyable! Our charger produces 40A continuous, meaning 10A is going into each of your 4 batteries at all times, (from start to finish) unlike conventional chargers that taper off halfway through the charge and take a long time to actually complete the cycle. What this means for you, is less charging time and more fishing time, which is really all that matters, correct?- It is extremely compact, with convenient mounting options that will make installation a breeze! Heavy Duty aluminum alloy body works great as a heat sync, plus creates a robust charger that is nearly indestructible.
- No buttons to push, lights to diagnose, and no long user manual to ponder over. Simply mount it, connect it and use it!
- This charger can also effectively charge your AGM or SLA batteries, (when charging these types, we recommend disconnecting the charger soon after the batteries become fully charged).
-
This charger can also be used in many different configurations!
- Example: 1 battery = 4 positive leads and 4 negative leads, you will now be charging at 40A to 1 battery.
- Example: 2 batteries = 1 lead set to each battery, remaining 2 lead sets are empty, now you are charging each battery at 10A Since each lead set is 100% isolated for all the others, this charger is truly versatile! If you at any time have questions about using this charger in your application, please contact us freely, we would be more than happy to discuss your needs with you and help you make the best decision. Your satisfaction is, and will always be our first priority!

Defective on arrival
Second ball defective.
First ball received would not light.
Second ball battery charged and locked. When unlocked to switch on light, the cylinder stuck in the ball and will not come out.
I'm very disappointed. I've sent back and hope the third functions properly.

Our Dog Is OBSESSED – Night Play Game Changer!
This light-up dog ball is a total hit in our house. As you can see from the photos, the glow is bright and easy to spot even in complete darkness, which makes nighttime play so much safer and more fun. The motion-activated light turns on instantly when my dog nudges or bites it, and the 90-second auto glow is perfect.
The silicone material feels soft but durable, gentle on teeth, and my dog loves carrying it around. USB-C charging is super convenient, and one charge easily lasts multiple evening play sessions. It’s also water-resistant, so no worries about grass or dew.
Perfect size for small to medium dogs, and it keeps my pup engaged and active after sunset. Highly recommend for anyone who wants fun, visible, and stress-free night play with their dog!

Better yet imporbable than the original LaRoo Ball
I owned the LaRoo v1 (old version of this ball) my 100lb lab loved it. It was the first light up toy to resist the strength of this jaw. It glowed bright enough and stayed on long enough to be fun for the dog in the darkest settings. Unfortunately I was stress testing it and he was able to unscrew it at some point and destroy the ball. Supervised it was great.
Onto this new one. It glows brighter for longer, great improvement on the original red one. My issue comes with the cap. They changed it from a threaded screw on cap to a bayonet mount (push in turn 1/16 of a turn its locked) the issue is that the bayonet plug was a few mm too short in tolerance and slipped out on our first play session. Its not nearly as secure as it once was. That being said a couple rounds of electrical tape around the perimeter of the plug and it now fits securely in the slot and is safe for puppy. This is a hard ball comparable to a baseball in size and softness. It doesn't make noise. The dog LOVES it. Its his favorite toy. If your dog plays fetch they will love this toy.

Not practical
I really wanted to like this ball, but it didn’t work well for us. The rubber is very hard and heavy, which made it difficult for my dog to catch it in the air and it was less enjoyable to play with overall. After only a short time, the plastic lid got stuck, and now I’m unable to open it to recharge the ball.
The light feature is a nice idea, but between the hardness of the ball and the charging issue, it just wasn’t practical. Disappointing quality for the price.
