Yeah, I had ran it a while using the lithium battery pack while mowing a bit and so it was entirely my fault. By the time I smelled the lithium, it was too late to kill everything. Stupid mistake... Regardless, I'd never use one anymore to do more than start a mower, tractor, or car, let it run a few min, then switch over to a lead acid. Or just stick to using a lead acid booster. 3 Share this post Link to post Share on other sites
TC10284 111 #28 Posted December 23, 2020 (edited) As a side note, I've tested starting some of my 300, 400, and 500 series with a battery as small as a UB12180 (12v 8aH) AGM (I think) battery . It worked fine. Although I'm nervous to run it too long with that too. Concerned it would be too small to handle continuous charge while running WOT for a while, like mowing. Although I assume it would just boil out the acid in the battery and melt vs explode. I don't really know. I'm not willing to try. I'd consider it on a 211-3, but the dang gas tank is right above the battery, so...that's a no-go there. Edited December 23, 2020 by TC10284 Share this post Link to post Share on other sites

You didn't try that did you? Diode or fuse in the cable should be fixable. I've done quite a bit of research and I want a lithium jump pack but I don't want to just blow $100 either. Probably should start a new thread... No, didn't do that, they are known for blowing the diodes for high amps Share this post Link to post Share on other sites

I think AGMs do better with a slightly different charge method but I think they will work as a replacement for the regular SLA battery. After all one can buy AGMs for a cars and trucks from most part suppliers 1 1 Share this post Link to post Share on other sites

One like these. https://www.amazon.com/s?k=UB12350&ref=nb_sb_noss_2 More expensive, definitely, than a 400cca battery from O'Reilly or Walmart, but I figured I could just take this out and use it on a solar panel for something when not being used by a tractor. 2 Share this post Link to post Share on other sites
Vurge 158 #36 Posted January 1, 2021 I've gotten to the point where I'm considering a12v lithium battery (smaller and lighter than lead acid) that I can just move from tractor to tractor. For convenience I'd put Anderson type plugs on the battery and tractors. Share this post Link to post Share on other sites

adsm08 2,433 #43 Posted January 1, 2021 My collection is not nearly that extensive. I only have five tractors, and one is going to be for sale once it runs. Two of the other four are in pieces, so I don't need to worry about batteries for them just yet. But I get U1 batteries for like $20 a piece. Share this post Link to post Share on other sites

ohiofarmer 3,314 #45 Posted January 1, 2021 I just got a miata battery from my buddy. It is a nice one-a sealed unit. I put it on the 1.5 Shoemaker charger last night. it started out at 4 volts and is now approaching twelve volts. Usually a dead one with one cell shorted wont go that high, so maybe it will come back all the way. The manufacture date on that battery is Dec 1919. he drives his Tesla and let the other car sit too long. Lesson there somewhere. 1 Share this post Link to post Share on other sites

I suppose that as the smaller AMP ones fail they have too little left where the 420 AMPs fail but still have 200A or so left in them. I agree with you there. I modified my Craftsman GT5000 to take a small car battery. Battery is from 2013! Never had a U1 battery last that long. 1 Share this post Link to post Share on other sites

They're definitely expensive but I'd be interesting in trying one sometime. Sounds like you learmed the Lesson the hard Way. A Lithium Battery allway‘s requires urgently any Battery Management System (BMS). Some battery types have them built in ( i.eg. for Motocycles some for RV) some don‘t. but before charging a Lithium System - independently if Lipo, lifepo, lifepoy, or even liti you have firstly to check what kind of BMS is required. as a thumb rule, you can mostly see it on the Max.Current they can be support. Battery with high Power have to have an external BMS, otherwise they can not support with such high Amperages. On Starterpacks the chargeport is normally restricted once by the Charger/ Chargerinput. that passes not the discharging leads, to be able to support that much Power as they Did. So this Starterpacks can be used, but the Charging port must be separated from the rest of the Tracta, what normally not a Way a Standart tracta goes. btw, i didn‘t like a lithium burner on any of my Vehicles. i work with simple VRLA Battery since years with best results even on my Racing quad, Motocycle, and all my Tractas. Lithium batteries have the ability to be charged with all power they get. The problem is hereby the Inner Batterytemp also. That is one of my hardest dis in my opinion. - never recharge a Lithium Battery with full current below 0*C Batt temp, otherwise a self ignition can be occurs on Lithium batts. That is also a reason, they must be temp protected what is normally also included in a BMS. So Lithium battery‘s are giant powerstorage, but not sensefully be usable for all envoirements. 1 Share this post Link to post Share on other sites

I got similar ones of a different make and still commercial grade to use on some things here. Certainly appears to be very heavy duty and easy to disconnect for convenience or emergency. 2 Share this post Link to post Share on other sites
