Lithium Battery upgrade

Anyone use lithium battery for their house battery bank. Looking for new ideas,  Thx

Interested.

Im also interested but the price is insane.  I can buy house batteries group 27 for about 100 a pop shop price.  Unless i decide to go low carbon foot print, live board/off the grid I cannot justify the price.

Unless battery manufacturer wants to sponsor a 2859 YouTube channel 😂😂😂😂 ill stick to my current batteries.


If the price drops on them to a couple hundred I see them being used by the average Joe.

Id be willing to bet some bass fishing guys use them, guys who run trolling motors for hours on end.  I also bet they are sponsored or are charter guys.

@oscar1 I haven't seen anybody using lithium batteries in express cruisers.

If you want better performance from your house bank, take a look at thin-plate pure lead (TPPL) batteries such as NorthStar.  They last longer and recharge faster than lead-acid batteries.  I've been using them for a couple years.  

Here's an example.

If you are serious about Lithium butteries they need to be treated differently than your traditional battery and need to be housed in something that can contain a thermal runaway condition.

Here's a video we watch every year on thermal runaway as part of our recurrent training. We generally have about 50 laptops on board being used.

Lol I’ve seen that video way too many times.

Indeed. I figured now all the "others" can partake in the misery 😆

I just looking to take some weight off the boat because i have 4 agm group 31 batteries  right now which at 72 pound each do the math. so one for each motor and two for the house use. 

YYZRC

What’s the reason for a dedicated starting battery per motor? Would it be possible to eliminate one starting battery?

Ian

I'll take the weight over burning lithium batteries anytime. And I'd rather have one per engine - just in case.

And to think these were in the rear of B787's uncontained until the back end caught fire....
