PT says, “For my part I'd love to hear of someone with a similar use pattern to mine using LiFePo4 at -34 F as a "weekend warrior"…
Fair enough - your operating requirements are a somewhat unique situation (per past stated parameters…), and it’s
great to know that the LTO option exist - but are most others to assume that LFP’s temperature parameters are somehow insurmountable??
From my perspective, the opposite is true via either interior mounting, built-in heater circuitry or by using an aftermarket heating pad, and bear in mind that although charging needs to be avoided below 32d/f, still, LFP’s are capable of discharging down to -04 d/f, and (for those unable to solve for low temps) consider that the extra (approx 100%, per case volume) power density helps to mitigate recharging until ambient conditions might improve…JMHO… My solution (two 200a/hr LFP’s) was to opt for interior mounting, without added optional heaters…
