Daniel French Posted November 16, 2016 Author Share Posted November 16, 2016 The PCA of the 10Ah battery is 480A and from the 7.5Ah 360A. Link to comment Share on other sites More sharing options...
Alan Archer Posted November 16, 2016 Share Posted November 16, 2016 This was the particular point in the article that I was referring to, how are you supposed to stop it charging if on a long journey?AlanAt this point, the charge should be disconnected but the topping charge continues while driving. Li-phosphate is tolerant to some overcharge; however, keeping the voltage at 14.40V for a prolonged time, as most vehicles do on a long drive, could stress Li-phosphate.

Roger Ford Posted November 16, 2016 Share Posted November 16, 2016 This was the particular point in the article that I was referring to, how are you supposed to stop it charging if on a long journey?You can't. However, as far as I can see, 14.4v for four cells is considered a mild overcharge so while it's not ideal for the longevity of the cells, it's not really going to do them any harm. Sources vary as to whether the maximum charge voltage is 3.5v per cell (=14v total) or 3.6 (14.4) or even 3.65 (14.6). And apparently the cells can usually manage up to 4.2v (16.8) without serious damage.It would seem to be worth while checking your alternator/voltage regulator output if you get one of these. If it's providing a bit more than the typical 14.4v it's not going to be good for the battery. Link to comment Share on other sites More sharing options...

OliverSedlacek Posted November 16, 2016 Share Posted November 16, 2016 I've been running a Lithium battery for nearly a year now, having convinced myself that the point had come to stop theorizing and to just give it a try. All I can say is that it works for me, cranking my XFlow better than the old lead acid batteries and it survived several accidental (caused by a wiring fault) complete discharges. I've never bothered with a special Lithium battery charger, but the XFlow does have the advantage of no battery drain when the ignition is off. The weight saving per pound spent is unbeatable, but then again I only spent £160. Link to comment Share on other sites More sharing options...
7 wonders of the world Posted November 20, 2016 Share Posted November 20, 2016 Oliver,Which make model did you opt for please? Has anyone got a link to Carstens battery - tried Googling but the site would let me in ! Link to comment Share on other sites More sharing options...
OliverSedlacek Posted November 20, 2016 Share Posted November 20, 2016 It's a 14Ah Skyrich YTX20HL-BS, see http://www.skyrichbattery.com/p581/HJTX20HL-FP%3Cbr-/%3ELithium-Ion-Battery-YTX20HL-BS-PW/product_info.html Link to comment Share on other sites More sharing options...

OliverSedlacek Posted November 24, 2016 Share Posted November 24, 2016 No problem so far with cold weather, coldest ambient has been down at 4-5C. I'm unlikely to take the car out below -5C. Link to comment Share on other sites More sharing options...
