If I used it for hunting that would change things though. One thing I did recently do is install a voltage switch which turns my active balancer on once my cell voltage goes over 3.37v and turns it back off if it drops below this.. |

Theres no reason for the insulatlion you speak of as the heater are there for the foremetioned reason to prevent plating damage from charging in freezing temps not to heat the battery to 70 degrees. They likely only heat the battery to to 10 degrees or so as anything over 5 degrees will accomplish the job. They use the low watt density silicone heating pads like you would find in a heated vest. They are typically sold for RV or off grid solar applications. They do not heat the batteries unless the battery is hooked up to a charger and it's below freezing |

Re: Allied lithium 48v 150ah
If it only heats the battery a little above freezing when charging, a couple of hours off the charger the [bare] battery will be down to almost ambient temps which here vary from just below freezing to 15 below F which according to the specs [if I am interpreting them right] is below their safe discharge temps.

Re: Allied lithium 48v 150ah
Huh….I didn’t know that. I’ve not seen such a battery for sale, but then, I’ve not searched for them either.
I hunt in Pennsylvania and the temps (in the fall\winter) can be anywhere from 60degrees to 15 degrees. I do not have any type of heat source keeping my battery pack warm. OTOH, I'm usually out for only a morning or evening "session" lasting at most, 5 hours. My cart is kept in a heated garage so charging is not an issue. I've often considered using a 12V "mini" fan type heater and enclose my battery box (easy to do) and run the mini heater off of my 12V Marine battery. But I get all the performance out of "what I need" now, so I see no reason to do this. However, if the cart was out for a 10+ hour day in below 32 temps, I'd likely consider some sort of battery heater. FWIW |

Re: Allied lithium 48v 150ah
Discharging Lithium at low temps is not a damage issue. You lose tons of performance though. It's really only charging that you have to worry about unless you plan on running your golf cart in Antarctica. :-) While running on cold weather, your battery will self heat somewhat due to the high internal resistance.

Ive found this touchscreen interface for the battery info handy although im sure the geek in me finds it more useful than most. I cant wait for warmer sustained temps as Ive only been able to test in cold weather so far and it does take a couple days for the battery to acclimate to ambient temps. so far we get one day of temps in the 50s and the next in the 20s. |

Re: Allied lithium 48v 150ah
I plan on picking up the 150ah version of this battery sometime the end of next week. I will keep you posted.
