Has anyone tried Lithium batteries in their Ural??

Lithium has a different charge rate to lead/acid/gel so theoretically requires a different regulator….🧐 anyway, the main gain would be less weight…..in your wallet. 🤣🤣 Guess I need to study up on the technology….

I've just read through this, and as usual, Lithium batteries aren't all the same. www.motorcycle.com/products/lithium-motorcycle-batteries-myths-vs-realitiesAt the Harley workshop where I work a couple of days, there are plenty of guys who want to save weight and get better performance, but they buy the cheap batteries and inevitably kill them by allowing them to discharge. The only ones to get are the ones with the BMS (Battery Management System) that prevents over or under charging. A YTX20 from Battery World is $249.00 weighing in at about 6 kgs. A similar size SSB Powersport battery from Dick Smith online in Lithium is $441.00 weighing in at about 1.4kg, so it would need to be a whole lot better in performance and longevity to make it worthwhile. It doesn't say whether it has a BMS. 4.5 kg isn't worth the cost for a weight saving, but if it helped with actual performance, perhaps it might be worth the additional pennies. As with everything internet based, it's hard to know what to believe unless you try it for yourself.

BatteryWorld is expensive……I use these. Three years Ok so far. $70.00 👍

I've used a local supplier and can get 20L batteries for about $110 delivered to the workshop. Three years is pretty good for a $70 battery - well done!

Hi Michael. Having done a little work with lithium batteries before, by installing 2 x220 Amp/hr deep cycles in my caravan. In doing this I also needed to create a dedicated Lithium profile in my Solar array and install a new AC charger with a lithium profile. Anyway, you are completely correct, in that not all Lithium/Fe/Po4 is created equal. The chemistry has become more stable, with the introduction of the Po4 component and when combined with an internal Battery Management System (BMS) they are pretty much bullet proof. From what I know, there are 2 methods of production for LipoFePo4, one called Cylindrical and the other Prismatic. The safest is Prismatic (with some Caveats) Read this bit from Baintech. baintech.com.au/prismatic-cells-vs-cylindrical-whats-the-difference/#:~:text=Prismatic%20Cells%20are%20the%20superior,%2C%20assembly%2C%20and%20materials%20used. The "SSB Powersport" Lithium motorcycle battery professes to be constructed using the higher grade Prismatic Cells, But what of the caveats in the article?? It is worth noting that depending on your "Google" search SSB Powersport is only one of many companies using batteries made by "Skyrich" They claim to originate in the USA and/or China. If China, that isn't such a bad thing given China produces 75% of the worlds Lithium Batteries. In addition, "Skyrich" also state that all of their batteries have a BMS in them to comply with various world and Eu standards. One of their batteries with similar CCA to the standard Yuasa YTX20-BS (really about 18.5Amp/Hr) and 270CCA, actually puts out 290CCA at 14Amp/hr. Weighs 1.1 KG but more importantly, the charge/recharge cycle is four times that of a lead acid, does not self discharge and supposedly recharges from minimum to Max in about 6 Minutes via your altenator. Food for thought. Cost was $220. A question to the "brains trust" is: If trying to match a lithium battery, is it important to match CCA or Amp/hrs?? If I match to 20Amp/hrs the Lithium provides something over 420CCA. Almost double that of the standard Yuasa. Do I really need 420CCA, when standard is only 270CCA? Most lithium Batteries tend to only quote CCA.

While on the topic of Lithium Batteries, I thought I should clarify my interest in them. As most of you know, I am setting up "Ruby" with a winch. So, I am grappling with how to power said winch, As I see it, I have 5 choices. 1. Use the existing Yuasa battery and hard wire to the winch? 2. As Tvan did, use an Anderson to Anderson jump over cable? which takes power from either the starting or aux battery? 3. Use a dedicated additional battery. Either AGM or Lithium?? 4. Use the existing? But carry a lithium Jumper Pack which could be used on other vehicles. 5. I was toying with swapping the standard Yuasa to winch duties. Then powering "Ruby" up with a Lithium. (I am guessing Lithium isn't going to run a winch very well??)
