[RE-wrenches] LiFePo4 Low Temp Charging Damage

[Mark Frye]

Folks,

If I have a charger that does not have low battery charge cut-off, I can 
get in trouble if I have a frozen pack and apply a charging voltage.

But, if I start with a pack that is above freezing and keep a trickle 
charge on it, can I keep that pack safe from freezing and damage?

Or at some point, as ambient temperature drops, the pack will freeze and 
be damaged anyway?

Thanks,
