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.

Awsome! My helix g2 chirp ice unit is lovin it

GREAT POWER!!
