Going out testing a Harley lithium battery on a 300xs

[Pachanga_rick]

People posted it won't work, some posted it will .. so I'm testing it. First, It's a nice weight savings in the stern..

It's 790 CCA and runs a Harley with more electronics than Best Buy..

Boats behind the house ready to go....

Mercury recommends 1000cca for computer to operate properly on opti motor. Post results, thanks

Lithium batts in bikes now. Cars boats next. Its the future. Read it in Cycleworld few years back.

If you don't mind, let it sit for 2/3 weeks, perko switch on, no charger and let us know.

Thanx NP

Why would you do that? If there are any power draws it will kill the battery. Not a test of a batteries ability to run an engine, just purposely trying to destroy an expensive battery.

If there aren't any power draws it'll be fine. I have lithium batteries that haven't been charged in a year or more that are still ok

I'm OK with no charger for a year, sorry about leaving the perko on, I have no draw on mine on or off.
I wanted to know if they required constant charging or maintenance charges all the time.
What is your cca on your lithiums?, What do they weigh?, What do they cost?

My "fat" batteries are 1000cca, will sit for months, and don't get any maintenance till winter time.
Yes they are heavy like me. :-)

I still have 4 cell Ballistic batteries that I used to use for trim batteries that are good. Bought them 4 years ago and they haven't been on a charger in over a year. Still good.

I've had great luck with Antigravity lithium batteries too. Used two 24 cell batteries tied together to crank. Even with 240 lbs of compression I couldn't kill that combination. I bet I could've cranked it 50 times if I wanted. Currently run a Braille lithium. So far so good but it's not a cheap battery. Best bang for the buck are the Antigravity batteries

LI-ON batts will hold charge a LONG time, maybe decades. Gonna put "Battery Tender" out of biz. I got a couple drills that one rarely needed and will sit for a year, as good as last times used. And run them flat out juice, and charge right back up fine. This aint the old "Ni Cads"

Only thing is on your charging system (boat) must be capable of knowing what its charging so something don't "let the smoke out". I know older IL 6 Mercs, do NOT like AGM batts,. but I'm no wizard electrics. Just damn good at letting the smoke out wires.
Search info LI-ON batts net. Heavy ass flooded, etc batts? Soon relics the past.........

I bought this a few months ago, it's been sitting in the garage.. Just got around to installing it. No pre charge, no problem.. fired right up.

The wife and I put around 70 miles on the boat today. A good amount of idling, some runs over 6k, but most at 3500 rpm.

Stopped at 3 bars and each times re starting was not a issue.

Overall it's positive result.

Sounds like you might have started a new go fast trend.
