Lithium Flasher Battery for Vexilar FL & FLX Series | Rechargeable Lithium ion - 12V 7.5Ah | Only 1.3 pounds | Featherlight by Norsk

Nice. They are so light it's hard to believe they'll have the power. I use in a fairly low-draw situation (using a Renogy solar charger with Lithium charging capability - this battery being the "Li-on" type, float at 12.6V to charge them with my solar panel - have all in in a cooler, have two of these and a Samlex 120v, 125W sinewave inverter.) I did discharge tests, and they worked perfectly. The seller sent me the techy data sheets upon request, so they ARE available. Don't recall how many amps they can push, but for me, I won't do more than 15 and I think it was 30 or 40.Love them.

I use this for my helix 7 fish finder. Battery only lasts a few hours. The $20 battery last a lot longer than this one. Would not recommend buying this battery.

Unfortunately this did not work for my application.

Great product! Extremely light weight! Very useful for the mobile ice fisherman! Had no issues with below zero temps. Also used for pack in hunting camps.

Very light but still powered my vexilar just fine, haven’t used it for a all day trip yet but it seems promising.

I’ve had this battery for 10 months and it only last about 6 hours before needing to recharge it.

Doesn't charge very easily

great battery very lightweight and holds a charge for a long time
