Jimbo - "6x 62 = 500???? I don't think so"

Sorry, I meant 8 batteries @ 6 volts each x 62 pounds apiece of T-105 batteries = 496lbs


Jimbo - "what are those figures based upon?"

Jimbo - "20-25 years? how long have they even been on the market?"

Cycle life testing has nothing to do with life on the market, it is based on lab testing. Since anything new that has a long life can not wait until it it's life is over to prove how long it can/will last, laboratory testing is all that can be done with mathematical projections.


Jimbo - "Again based on what, where R U getting these figures from?"

Here is a technical data sheet. I have read many of your posts and you seem interested in the technology. This data sheet specifies 2000 cycles not the 3000 I stated. But I have seen data sheets in the past stating 3000-5000 cycles. My math was based on 3000 charge cycles. But if you normally change your lead batteries every 3 years, the 2000 life cycles will still get you 20 years on your cart.

If you are interested in more info, please PM me.

Kbace6 i sent you a pm

kbac6

very interested, just like to know the source of your data.

take read of this article not to encouraging ?

Are you selling the batteries?

This is good stuff
 

Kbace6, unless you will be breaking forum policies, the heck with PMs, keep sharing your experience and knowledge.

Thanks for the info. Any links you would like to share to further educate? My google attempts have been hit and miss. Any major deep cycle players entering this market? I seem to remember Trojan was teaming with someone a couple years ago but heard very little after.

Thanks for the posts. I look forward to learning more.

Jimbo, No I am not selling anything. And I would never use a forum like this one to do so. If I were selling something I would just advertise. I am an EV enthusist who has been reading about and researching these batteries for the past 3 years. I have spent hundreds of hours learning about this specific Lithium battery technology. I attended the first Electric Vehicle Conversion Convention a couple of years ago. I plan to be converting a car from ICE to electric in the next 12 months using these very batteries. The cost is high and I have been hoarding my extra $$$ for retirement. So who knows how long it will take.

The article you sent is typical to what I have read many many times. There was no mention of LiFePo4 cells that I could see. But all the batteries in this article have 2 things in common. 1 they were all overcharged and 2 they all had a BMS attached to them. These LiFePo4 batteries do not need additional technology on them. They need a smart charger and good instrumentation to prevent over discharging by the user.

Here, try this, it is a long read, but here is one particular article where they talk about testing of these particular cells. Also if you poke around this site, there are several hundred hours of video to watch too.

Asking for a PM was meant to not have to flood the forum with a bunch of technical data, but you guys seem to eat that stuff up. My mistake. So I just included a link to my major, but not toatal source of info.

AJ, see the link I put in my reply to Jimbo. I may not hear from you for a while if you read all the info on the site or watch the several hundred hours of video, not to mention the video of all the battery testing.

The guy doing the videos is a bit of a windbag, but once you get past his bluster, there is a LOT of excellent info on the site.
