mindspin311 Posted July 17, 2019 Report Share Posted July 17, 2019 Are Braille and Odyssey still the best? What about construction? I think I remember seeing LiFePO or something was the new hotness? 1 Quote Link to comment Share on other sites More sharing options...
Bremsen Posted July 17, 2019 Report Share Posted July 17, 2019 (edited) Just bought a Battery Tender LiFePo to replace another older LiFePo I killed. No complaints yet. Neat little BMS that cuts the battery off before voltage gets too low (what kills LiFePo batteries especially) so we'll see how long it lasts. <$200 for the 300cca version (easily turns over our 3.0L). Its weighs almost nothing. Edited July 17, 2019 by Bremsen 2 1 Quote Link to comment Share on other sites More sharing options...
Snake Posted July 17, 2019 Report Share Posted July 17, 2019 We run Braille AGM's. 1 Quote Link to comment Share on other sites More sharing options...
Mchin Posted July 17, 2019 Report Share Posted July 17, 2019 Odyssey Batteries have gotten worst over the years. Their PC680 just doesn't seem to last as long as they use to. Braille is good, if you want to spend some money their lithium G20 is a beast. Or on the lower end Deka's ETX20 or ETX30 are great for their price.

karman1970 Posted July 17, 2019 Report Share Posted July 17, 2019 I bought some Anti-Gravity batteries for a couple of my bikes several years ago, so I got a bigger one for our Civic. Seems to work ok so far. Quote Link to comment Share on other sites More sharing options...
pintodave Posted July 18, 2019 Report Share Posted July 18, 2019 Is Penn still the OEM for Braille? Penn's were a good bit cheaper the last time this convo came up Quote Link to comment Share on other sites More sharing options...
zack_280 Posted July 18, 2019 Report Share Posted July 18, 2019 I'm using this in the E46. Not super cheap, but it's been pretty reliable so far. We had an ignition short and I cranked the car for ~5 minutes before completely killing the battery. That seems reasonable to me. If you lose the alternator, you don't have much time, so be sure to monitor voltage (or better yet, current). Note that you have to use the manufacturer's charger if you kill it because it has safety cutoff (you'll read 0V if you kill it and can't charge it through the posts). https://www.amazon.com/gp/product/B00I69WDUW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Quote Link to comment Share on other sites More sharing options...

Check amazon though, I think its about few $$ cheaper (I paid full retail). Mine came with a harness/reset button and hardware. 21 hours ago, wvumtnbkr said: How did you attach your cables to it? Thanks! Rob R. Yeah, mine came with the harness to charge/reset it as well as the terminal hardware. Might try calling them, maybe they'll send some to you FOC.

Considering it is used in all the top forms of motorsports for over 10 years... no. But Braille has been proven time and time again (F1, Indy, IMSA, WEC, Australian V8 Supercar) But I would not use a Chinese lithium battery either.

55mini Posted July 18, 2019 Report Share Posted July 18, 2019 So we watched a lithium in Spartans BMW start fire and torched the inside of the car? Has something changed to make them better and safe? I think it was being over charged by the alternator or something to that effect, seeing that happen we have chosen to stay away and run normal lead acid stuff. Maybe the new "smart" changes the issue. 1 Quote Link to comment Share on other sites More sharing options...
Team Infiniti Posted July 18, 2019 Report Share Posted July 18, 2019 While on it’s last leg, we are still running a 50 pound optima battery…from there it will be a Walmart lawn tractor battery next. Quote Link to comment Share on other sites More sharing options...

theblue Posted July 18, 2019 Report Share Posted July 18, 2019 I think that was last year. When the fire crew see's the lithium bomb they tend to run away. Quote Link to comment Share on other sites More sharing options...
Jab31169 Posted July 18, 2019 Report Share Posted July 18, 2019 Its been my reason to stay away from those. Is it worth the 30lb reduction...I don't think the juice is worth the squeeze at this point in time since we still have some more areas to get weight out of with a little less risk.

Bremsen Posted July 18, 2019 Report Share Posted July 18, 2019 We all walk around with lithium batteries all day every day. And LiFePos are much more stable than whats in your iphone or laptop. Overcharging (high volts) and puncture are the two main concerns with LiFePo batteries or any batteries for that matter. Get a proper charger and make sure its secure and protected in an accident. It negates some of my weight savings, but this is my battery box: https://www.sportsmansguide.com/product/index/us-military-surplus-waterproof-m2a1-50-caliber-ammo-can-used?a=1586610 Quote Link to comment Share on other sites More sharing options...
wvumtnbkr Posted July 18, 2019 Report Share Posted July 18, 2019 Whoa whoa whoa.... I won't run anything except a lifepo4 battery. Really stable and doesn't have the same fears as regular lithium batteries. I would not run any lithium battery except lifepo4. Totally different. No real difference in danger than a lead acid (which also don't like punctures or overcharging) Quote Link to comment Share on other sites More sharing options...
