With not providing enough usage time I upped for a 20ah Lithium battery that also came with it's own charger. The price has gone up about $7 from when I bought mine but it's still a bargain at the capacity and price including the lithium charger. I put it inside a waterproof Pelican case that I've used for years with a 12v 10ah battery. The Lithium battery even though it's 20ah is slightly smaller the the 10ah and it weight so little that when I pick up that case I can tell them apart because the Lithium Pelican case feels like it must be empty. If not submerged I think they could be used without a waterproof case.

That's a nice light battery at a good price, but it may not perform too well with your Lowrance Elite 7Ti which is for 10.8-17V while the battery has a range of 8.5-12.6V. As the Battery discharges, when it falls below 10.8V, the Lowrance might not operate too well. I had the same problem with the FPV Power 17.6ah lithium.

I've used the 7TI for up to 9.5 hrs and the voltage was still good and the old 12v 12ah flooded battery would have cut out already due to voltage drop. So after 6 weeks of use I'm very happy with it.
