Only downside to lithium batteries

I see a lot of people going to lithium batteries, me included. I use them for my livescope, 106sv and 93sv plus. I would not use them on my 24 volt Terrova due to needing to remove the batteries, to charge, in the winter. You can't charge the batteries when it's 32 or under. I remove my 23ah as soon as l come off the lake and charge in my shop. I have plugs for this. I can't imagine removing my trolling motor batteries under my front deck on my skiff everything l go fishing in the winter. How do you guys handle charging your lithium batteries under 32 degrees?

Wow I didn’t know there was a temp limit!

That is a consideration. Some places only have a few times a year that the temp gets down that low

Some of the guys on bbc forum are attaching this to the underside of their deck lids above their batteries to use and charge them when it’s below 32 degrees. Amazon.com

I figured somebody was using a heat mat to keep the temp up.

I don’t think they put this bee heater directly on the batteries as they commented attaching it to the underside of the lids…it gets up to 140 degrees warm. I would try double face carpet tape or something like that…to attach to the underside of the lids. For 10 bucks even slide it in battery compartment if there is room. Where there is a will,,,there is a way.

I have no idea but duplicate post.

Also,,if your using a lithium battery for starting and you have your electronics attached to same battery and air temp is below 32 degrees…turn your electronics on before launching and the lithiums will self warm alittle to create a easier start of the big motor.

Insulating the battery box could help also

No reason a digital thermostat controller couldn't be used to keep the battery compartment at the desired temp

Lowest temp I have ever seen on mine is 38 degrees. If you're that concerned, just charge them up when you get back from fishing.

The medium to higher end lithium batteries have low temperature charging protection. The lithium batteries in the 300 to 400 dollar range on Amazon likely don’t.

Other options, light bulb, pipe heating cable, roof de-icing cable.

TXpanfisher, my brother in law bought a 54ah Dakota 500.00 dollar battery and he Can't charge below 32 degrees. What brand has built in tempature protection?

Low temperature charging protection means the battery stops charging once it gets close to freezing. My apologies - I should have clarified that. Lithium batteries can't be charged below freezing or it will damage the battery. Warming mats or bring it inside are decent options.

Battery manufacturers are starting to make lithiums with built in heating. But, I think it’s only the larger starting/electronics batteries. You have to do a search to find out which ones are offering heated lithiums. Ionic is one. 125ah 12V Ionic Lithium Battery With Heater - Drewcraft LLC And this battery has been on the market for at least a year now.

Most all your battery manufacturers BMS system of their batteries have temp protection for overheating and cold built in the BMS of the battery.

so it seems you can't charge lithium batteries below 32 degrees but you can use them well below that ? ?

I dont use my boat for ice fishing. If its below 32F in my garage (unheated) for long enough to drop my batteries to 32F then its pretty dang cold out and not likely I am going to get the boat in the water the next morning anyways. I can check my battery temperature right now from my office using the bluetooth in the Ionics. Its 26F outside and my batteries are at 38.4F. I can think of one place I could fish tomorrow but I wouldn't be going until it got above freezing, so if I had to charge my batteries I would have done so 6 hours ago and they would be charged already... but if need be I would just go put an old school work light with 100W bulb in the box during morning coffee and those batteries would be above 32 in no time, give them a couple hours to charge up and then hit the water when its warm.

The lithium batteries charge stupid fast, plug in when done fishing and unplug before the temp starts to drop. Plug back in when batteries are over 32F, even if I forget its no worry.. they have low temp protection so they won't allow me to charge them when below 33F.

You can draw current (use them) down to -4F. That would be a fun challenge to find a place to fish with the boat when its -4. I've been in some cold weather while walleye fishing the river, but -4 is going to start freezing over the mighty mississippi even.

😁 Or mabe wait till it gets above freezing to go fishn. Here in arkansas, fishing below 32 is just downright COLD!!

You can go fishing when it is below 32 you just have to fish until it warms up outside :santa

I did not know about temp restrictions, so use to using lead acid type didn't think of that, thanks

I've not yet tried to heat my batteries but today I was working in the garage and thought I'd check and see about my lightbulb plan. Batteries were at 31 and 31.5 or close to it, I grabbed an old work light with a 100W bulb in it and stuck it down in the battery box being sure it didnt touch anything. I let it run for 30 min and then stuck my small fan in there that I use for drying out compartments. Within 30 more minutes they were both 38+. I have no doubt you could just run the light all night and keep them nice and warm. I may try and rig something up, I think I have a socket around here somewhere, then I would also have a plug in work light for messing around in there.

You could even add some 1/2 inch blue board installation to the compartment if needed.

Heater is a good idea but please make sure there isn't anything that could cause a fire. To me, been an electrician all my life, it's not worth it to me. I will stay with the lead acid batteries. Now when they live out their life, might have to give the lithium another look.

I would think the heat mat thermostatically controlled would be the best and safest option.

I agree 100%. You should use a thermostat with what ever heat source you chose. An incandescent bulb gets hot enough to start a fire if any combustible material touches them.
12-22-2021, 04:36 PM

I didnt even know you could buy an incandescent light bulb still? People still use them?

Ya'll making a mountain out of a molehill. Go fishing. When you get home, if your batteries need to be charged, charge them. They will be warm enough from being used. When they are fully charged, unplug the charger and your ready to go fishing again.

l'm not making a mountain out of anything. The sellers of lithium batteries, Amped- Dakota etc, tell you to not charge your batteries under 32 degrees or you will damage them. I am just relaying the info. If you don't believe them or chose to ignore them, that's up to you.

Rumors have it Walmart is developing a Lithium 100 amp lithium for around 300 plus cost…..with a 1 yr. warranty. Additional warranty can be purchased at 22 bucks per year. Big player like Walmart will drive the prices down I would think.

Apparently you are not understanding what Kevin and I are trying to tell you. I have $3,000.00 invested in lithium batteries. I know they won't charge if they are below freezing. I bought Inoic batteries just for the app. I know what the temp is. I have never seen my batteries below freezing. I fish and hunt in below freezing conditions. When I get home, if they need charging, I charge them. When you use the battery they will warm up.

It was 28 degrees here last night. It is presently 35 degrees now. Here is a screen shot of all 4 of my batteries. Keep in mind this is an unheated garage.

If they're below 32 degrees, warm em up by whatever means you choose. Or just charge them when you come back from fishing while they are above 32 degrees from use.

If they give as good service as the brand of lead acid deep cycles I would run them
