Lifepo4 Battery ....

[blueball]

I put an Ionic 100ah battery in and found that my onboard charger would work for it as well as my lead acid batteries. I have the Minn Kota Precision charger. Had to change setting on the charger but has proven to keep everything at 100%. it is a 3 bank charger.

The minnkota precision and the minnkota d will charge ionics great.The D series will auto detect and set the charging profile.

There seems to be a discrepancy between what my MK220 onboard charger and my new ECO-Worthy Smart Charger thinks "Fully Charged" means. Starter battery & AGM trolling motor battery were left hooked up over the last 2weeks. I'm going tomorrow, so I checked them with the smart charger and it said both were "good" and at 80%. I figured the "good" meant the battery was functional & the 80% was from them having been hooked up (in the boat) for 2 weeks. Not wanting to end up with a "dead" battery tomorrow, I brought the batteries in and hooked them up with the onboard charger. Within 30secs the charger said both were "fully charged" (as evidenced by the green light). I hooked the smart charger up to the AGM battery and it's saying the charge level is 14.8v, but it's still flashing on the screen that the battery is not yet charged to 100%.
It did the same thing on the starter battery, but that sucker is from 2019 ... so I had already purchased a new starter battery, and that new one is now the primary starter battery.
The ECO smart charger has a LED screen, but it's very hard to read (as is the Operator Guide) because the letters/numbers are so small. Probably would be easier to read if the back lighting was white, instead of blue.

I'll see how the 50ah Lithium holds up running the Garmin 93sv & Livescope system after 6-7hrs runtime, and will report on that tomorrow evening.

Got out today & the Lithium battery performed flawlessly for about 6hrs. Then the Garmin shut off and I couldn't get it to come back on, so I figured I'd run it dead. Got home & put it on the charger (test function) and it said the battery was "good" @ 80% and 12.3v .... so now I'm a bit confused. I'll give it another chance before giving up on it, but next time I'll be taking my old starter battery as backup in case I'm out longer than 6hrs.

12.3 volts for a LifePo battery has approximately 10% capacity, according to most charge charts.

Was the Garmin and Livescope the only thing connected to the battery?

Yes, that's all that was connected.

That would mean the Garmin/LS system is pulling ~6a/hr .... and 6hrs continuous running (36ah) is all I can expect from a 50ah lithium battery ??
Battery has been on charge for about 12hrs & shows 13.5v (0.0v input charge) which according to the chart is 100% charged & "resting".

One of the reviews for that battery on Amazon:

"*Edit: DC House has done right by me and had taken back the Eco Worthy batteries I purchased and provided a full refund. Grateful for the seller resolving this issue for me.*

Very frustrated my brand new batteries are around 95% of rated capacity. I have another manufacturers battery that tests over 102% of capacity. The seller is blaming my test gear even though I’ve tested another manufacturers battery on the same setup right before testing the Eco Worthy. There’s more than 6AH difference between the two batteries.

The other manufacturers battery is in the same price range as the Eco Worthy. As of today it’s actually $30 lower in cost.

Editing to add pictures of the discharge results. One battery at 86ah and the other at 96. These are not 100ah batteries."


May not hurt to contact the manufacturer if you run a couple tests on that battery and find you aren't getting your advertised amount of capacity.

Can you connect to the BMS via bluetooth?

Yeah I got that very battery last month. I have a small Gheenoe boat that is relatively lightweight and wanted to lighten the load from the 44lb deep cycle I had in the bow. I run my trolling motor, depthfinder, and bilge pump off that battery. To clarify; a clamp on 55lb MinnKota motor, a Garmin Vivid 5 CV, and a 1100 pump in the rear of my boat just in case. I knew the 100Ah would be more than enough and had doubts about the 50Ah but took the chance just for money and weight savings
.
Several weeks ago at Santee I used it all day fishing, two days. Even got caught in torrential rain a couple times and the bilge flipped on for a few seconds. If the trolling motor was down, the depthfinder was on. All day fishing the battery held up and when charging at night, it showed over 60% charged & recharged quickly and yes, easy to pull out and carry to the motel room.
Only thing is it seems I don't get quite the thrust from the motor but I'm not entirely sure that's not just in my head. Max Amp according to MinnKota is 50a. Voltage on depthfinder never dropped below 13volts. I've used it a total of 4 day trips so...
If it will live up to the longevity claims it will be well worth the money.
If you're only gonna run a scope I can't imagine you'd have any issue.
Edit to add: Just saw above possible issues. Note on Amazon, most give good reviews of this battery though there are a few that seemed to get a "lemon".
