Best lithium battery ever. May invest now for my boat. Pricey, but well worth it.

Once I fully charged your battery far exceeded my expectations! Having used several lead acid batteries and having to keep one always on charge to get me through the day I now have a battery that my solar charger will keep the voltage during the day and the battery will not only make it through the night but have enough power for the next day even if the day is cloudy.

Great product! Great service! Great company!

haven’t tried them yet.. but are very lite

Fished with my new Dakota lithium ion 10ah battery on a humminbird helix 7 for 7 hrs and it never came off 100% charge! Not to mention my whole unit with the new battery is lighter than just the old battery. Love it

I put this battery into my old Celestron powertank replacing a lead acid 12v 7ah battery with this bad boy. It was like 10 screws and a lot cheaper than buying a new one. Nothing against Celestron, I also have one of their newer lithium powertanks, but this was my first one and it lasted several years. The reason I need another is for astro-photography, cooling my larger main scope, and for simply longer sessions. Admittedly, I have not used this yet, but I have no concerns there.

So far so good fished with with a helix 7 for ten hours and it didn’t die. Threw it on a charger and it was charged in two hours. But for a hundred dollars it should be that good

I will be using with my Vexilar for ice fishing. Surprised how fast it charged.

Great battery well satisfied.

These batteries are amazing. Light weight and last. I replaces a 12v 12ah with this on my Garmin Panoptix, after 10hrs of fishing it only dropped .6volts. I also replace one in my camera, so between the 2 I dropped #7 in weight.
