I have been using the blue lithium packs for 18 months now, and can't fault them."I have been using the blue Lithium packs which have worked well, though more recently I have turned to 18650 Lithium Ion cells as they can be used for more applications other than just running a Fish Finder."
Wilson, the "explodo" thing started as a joke, and turned into a Chinese whisper a while back. I think Andrew Johns may have been involved (after a few beers). Keep in mind: your laptop is powered by the same li-ion battery pack. As are most of your power tools, and your shark shield. The li-ions in your VHF, phone and camera are a bit smaller. If you are worried about lithium explosions, charge all in your rechargeable electrical devices in your fire place, or in a fireproof sack. Like all batteries, if you get li-ions wet, they might die."Is it true that li-ion battery explode when they get water in them?"
Main reason is that stupid little switch on the side of the pack, My FF Transducer cable and battery is contained in a piece of 90mm PVC Pipe and its a bit of a pain having to turn that switch off when not in use, cos you know that little red LED on the pack well it will run your battery down.MrX said:Thanks bildad - Interesting.
Curious as to why you choose to put together a group of 18650's to power your sounder, rather than use the readymade blue pack - given the packs are cheaper, already circuit protected, easy to use (even for us electronics dummies) and come with a charger?
Finally convinced my dear old mum to replace her 70's cathode ray telly with a modern flat screen. Wore her down from "Bugger off son, the rank arena works fine"."I don't know why anybody getting into Yak fishing would use SLA batteries"
I found not enough amps for a bilge pump. See no reason why you can't use them on an aerator. The standard old "D" batteries are frustrating. Might have a play with my 18650's on the weekend."I might run some tests seeing if they can handle running bilge pumps and aerators."
Yep no problem, you can either get a 4 X holder or use 2of 2 X holder in series back to back, if the shape helps.spork said:I'm already using those cells for head torch. Have some extras and a good charger. Will grab a couple of those holders I think. Thanks for a really helpful post.
I note my sounders will operate on 10v to 17v dc. If I used 4 of these battries fully charged = 16.8v, giving me I imagine longer run time. Apart from the cost and (neglible) weight and size difference can you see any problem with doing this?
