Terrific video, it was a big team effort by Dayne and the service team at CartMart. The new lithium batteries are absolutely amazing and I’m reaching speeds up hill now at 25mph or better. My mileage is now at least 60 mikes per charge. Thank you Dayne for all your efforts time and assistance in getting this resolved. Best …Gregg
The max discharge is only for a limited time, so maybe it can max out at 350 but probably only for 20-30 seconds and then it was locking up because of the long uphill. Roypow now makes a “P” series with I think 160ah battery and is made for tough terrain…haven’t gotten it yet but when I’m ready for new batteries that’s what I’m going with (also have navitas 600a controller).
Yes your talking about the max continuous discharge rate. This Allied battery’s max continuous discharge is 180 and thus should have had no problem on this incline. To put it in perspective of why this battery should have worked, and why I kept saying it should have been good enough if the specs were true, is exactly what you said about the Roy Pow P series batteries. The Roy Pow P is 350 max output and 160 continuous which is LOWER than Allied’s max continuous output. But yet, I can almost guarantee the Roy Pow P battery would have had no problem with this ride even though the continuous is lower than the Allied battery. I’m frustrated I didn’t mention the continuous discharge in the video.. instead I just kept saying that the battery should’ve been good enough lol.
Thanks for the video.... "It would have worked with Roy Pow" is a speculative statement without doing it under the exact same circumstances. As others have said 350 is the max for so many seconds. That's a very important distinction that was not said. Agreed 100% ICON has a beefy controller then most. Also not mentioned was tuning it down to draw less amps (instructions are readily available in golf cart forms). I also agree he needed more continuous amp hours which he got with the new set up. Moral of this video (for me)... 105 amp hour in a stock or turned up ICON with less than a flat environment. Is not recommended for long drives.
350amps max, is only for like 5 seconds, and that’s it. That battery is probably only rated for like 150-200amps continuous draw. Very simply put, and contrary to your statement in the video, the battery will NOT handle the draw from the controller. This should have been easily diagnosed. The BMS is shutting the battery down for discharge over current! I am going with a 72v 105ah Allied battery. I have a 600amp controller, and the 72v battery has a continuous discharge rate of 300amps, and a max discharge rate of 650amps for 5 seconds. The max amperage of the BMS will cover my controllers demand, even in extreme situations. Your 450-500amp controller will Trigger your BMS to shut down when it reaches its max 350amps for a 5 seconds. Still trying to understand why you think a 450-500amp controller would work with a BMS rated for a max output of 350amps??? The new batteries installed were 60 continuous amps of discharge, and 160 amps of max discharge. 4 of these in parallel give you 240amps of continuous run time, and 640amps of max discharge! Imagine that!!! When your batteries BMS puts out enough amps to feed your controllers, you don’t have issues!!! Your understanding of the way discharge amperage works, is slightly off. Simple thing to remember, if your buggy has whatever sized controller, 2-3-4-5-600amps, it will at some point,call for that many amps. Under heavy load, steep inclines, it will pull that many amps. After all, that’s what it’s built to do, to give the motor all the amps the controller is rated for. But if your batteries BMS cannot sustain those demands, it will shut off, in the middle of your ride, or wherever you are when you exceed the rated draw, for longer than the rated time. These are FACTS!!!!
