Agreed! Cold weather is always tough on any battery chemistry, ours tend to perform above our expectations in cold climates however. As Superbikes mentions, we have many in use in colder climates without issue actually but it is always something to be aware of!
Lithium batteries are cool technology for many uses. I do not think I would run one for a main starting battery on an overland rig though. The main issue I see is their narrower temperature operating range. The Antigravity manual states an operating range of 23F-140F.
Hey Chris thanks for showing us the correct procedure to disconnect and reconnect the battery terminals to avoid a painful and/or expensive shorting of the wrench. When replacing a battery disconnect the negative terminal first. When reinstalling a battery connect the positive terminal first. I am curious if you used the house vacuum cleaner (like in a previous video) to suck up all that corrosion. Like the bathrobe too!
I don't know for certain but my guess is that large battery would take up a lot of under bonnet space. It may also be closer to the starter so there would be less voltage drop.
Awesome, albeit expensive mod! It does make a lot of sense for overlanding though. A single self-rescue from the middle of nowhere probably justifies the cost. In terms of value, I would rank it up there with a winch.
I have two one for the JL & YJ. I have the same battery management app. Also I have the CTEK battery charger and the antigravity jump starter pack. Always good to have backup. I have one for each Jeep and one designed for diesels (F-250). I used the same code from Tim & Kelsey. I was hoping you were going to clean the compartment.
Given the specific application of your new Lithium battery for use an old beat up Land Rover, it seems to me you could have instead spent the $1,000+/- on a "normal" battery and an emergency jumper battery, and you would still have money left over (about $750?) for much more necessary upgrades/repairs. Or, do I not "get it"?
Interesting video. That battery Is just a LITTLE pricey!😱lol We are passing through Tucson in about a week. I’ll keep my eye out for you. We may stop in at Sonoran Rovers. Cheers!
While accurate, our automotive series batteries are designed to be integrated into the OEM charging system on almost all vehicles. If you want to use our Deep Cycle Lithium Batteries, that's when you need to start looking into a secondary or DC-DC charging system.
I have a question. Lifep04 batteries cannot be used below zero without damage due to the chemistry. How do you get around this? Does it have a low temp disconnect? I don't see anything on the website about this.
Generally, they can be discharged when below freezing, but they can’t be _charged_ below freezing. The “low temperature cutoff” is actually low temp charging protection, meaning the BMS wont allow significant charging current below freezing. Some batteries designed for cold weather use get around this by adding heating elements to ensure they are at a good temperature, but this comes at a cost.. Also where this is mounted, it should mostly remain above freezing or get up to that temperature after some operation time, if it’s very cold (overnight camping in freezing weather, etc).
I was in Bridgeport, CA near Bodie State Park and it was 5 degrees F, the Jeep started up. They must have something like that, email their support for questions. Now I don't know about - temps.
Hey! When in extreme temps and you experience a non-start issue like a dead battery and the ReStart function doesn't work, turning on a low-draw item such as the headlights for about 90s is usually enough to chemically activate the battery internally which will allow for normal starting at that point in time. There is a ton on info in our manual regarding these types of situations as well!
Take another look: the key is turned in the clockwise direction to start the vehicle. Most vehicles have the ignition switch on the driver's righthand side of the steering column. Consider this: on a right hand drive vehicle you operate the shift lever with your left hand.
