That’s interesting about the 100% , have read that before . Yet the one I bought 100 amp , stated in the manual store at 100% .Seems to be conflicting positions on storage .
lithium battery questions
- Thread starter Doublebluff
- Start date
I got caught in the wind one day farther out than I should have been . Just fins , and oars , I was in doubt for awhile if I was going to make it back in . Last time I was in a pontoon boat without a motor .
They sell a handle extension for the Minn Kota, that way if you do go forward the handle is laying right by your side to guide the boat . I find it easier to go backwards as fast as I want , if wanting to get to another location , and just look over my shoulder occasionally to avoid anyone. Fins to guide .
Backwards for me too. In fact I turned the head around on my motor.
Yup , same here.
How to Find Happiness With LiFePO4 (Lithium-Ion) Batteries – Solacity
By: Rob Beckers You have just sold your first-born into slavery, remortgaged the house, and bought yourself a lithium-ion battery! Now you want to know how to take care of your precious new purchase: How to best charge lithium-iron batteries, how to discharge them, and how to get the maximum...

This is a long article but it is an easy read and pretty much covers any questions you may have about LiFePO4 batteries.
From the article
To sum up, for long and happy LFP battery life, in order of importance, you should be mindful of the following:
- Keep the battery temperature under 45 Centigrade (under 30C if possible) – This is by far the most important!!
- Keep charge and discharge currents under 0.5C (0.2C preferred)
- Keep battery temperature above 0 Centigrade (freezing) when discharging if possible – This, and everything below, is nowhere near as important as the first two
- Do not cycle below 10% – 15% SOC unless you really need to
- Do not float the battery at 100% SOC if possible
- Do not charge to 100% SOC if you do not need it
- KISS (Keep It Simple Smart-person) – avoid series-connected lithium batteries, avoid heated batteries unless absolutely needed
That is it! Now you too can find happiness and a fulfilling life with your LiFePO4 batteries!

Thanks for the info . As said above in one of my posts, my manual that came with my LFP stated store at 100 % I suppose I could check with the manufacturer, but that’s what’s in their manual.How to Find Happiness With LiFePO4 (Lithium-Ion) Batteries – Solacity

It certainly holds it charge , I hadn't checked it for about 7 months , and it was still at 100%. I put it away last August after returning from a six week trip to Montana, where it got used frequently. It’s been stored these past months well within the temperature range you posted . O - 113 F . Pretty crazy my manual says store at 100% . I’ve read this enough now , I’m going to get it down around 80 % when stored . The battery is less than a year old , bought early June last year .
I guess I don’t have that style , mine as said after 7 months still sitting at 100 % .
I was so used to monitoring my AGM’s during the winter, checking periodically to maintain, it appears this LFP requires no attention. I let it go the 7 months dropped the ball on it , having ankle surgery in November, just didn’t think about it like normal .
After I bought my battery I got on the Dakota Lithium battery mailing list. This is what they say about charging.

Off-season?
According to all the literature I have come across the discharge rate of LiFePO4 is between 1% and 2%/month. My Dakota 100ah came from the factory with about a 30% charge which is also what the literature says a new LiFePO4 battery will be charged at from the factory no matter the brand.
If you charge to 100% and leave it for a year it will still be at 76%-88% SOC. Any literature I have seen states the only time you can damage a battery on the low side is keeping it stored at less than 10% SOC. You are overthinking this IMO.
I am not overthinking this in the least. I merely responded to the quote from the Dakota brochure that was posted. They said "so don't forget to fully charge your batteries every two months during the offseason."
I don't think its an issue either. But apparently Dakota does??
Should I charge LiFePO4 to 100%?
LiFePO4 batteries are a new type of lithium-ion battery that offers advantages such as high energy density, long lifespan, and lower environmental impact. However, whether or not to charge them to 100% is a controversial question. In this article, we will analyze this issue and provide some...

Just another article that discusses the reasons why you should not charge your LiFePO4 battery to 100% on a regular basis. I am 4 years in with what appears to me to be identical performance parameters with my Dakota 100ah battery. I avoid charging to 100% based on numerous articles I have read regarding this chemistry. I keep my battery in the 50%-90% range most of the time and periodically charge to 100%. The only literature I have seen that advocates charging to 100% and keeping at 100% is dakota. In fact, the literature I have read about this chemistry and its charging and storing parameters were one of the main reasons I paid the big bucks for my battery.
When my battery is 10 yrs old we can compare notes on how my charging routine and your charging routine compare. Good luck with your dakota, I love mine so far.
Regarding charging it appears we will just have to agree to disagree.

The obvious solution to this battery BS is just go fishing more frequently.
You will be happier and so will those batteries.
The fish might not like it, or will they.
Here on Vancouver island, 2 months without fishing is extremely rare.
Exactly. What I always respond to threads about "do you practice your fly casting." Sure lawn casting is fine. Fishing is better.....lol
Thanks for posting this. I occasionally use a trolling motor on my Fishcat scout and going forward, water gets pushed around me and into the back. Kept thinking “I need to figure out a solution so I can get pulled, not pushed”.
Dar, this was one of those solutions that made me feel like a moron. Why didn’t I think of this…
