That's great!!! Last time my Florida garage hit -40° my car wouldn't start :1rotfl::1rotfl::1rotfl:

A 15kw golf cart battery would be an all day battery of about 120 miles. That would be a cell price of around $300 plus another $500 for support pieces. $800 all-in with a cycle life of >10,000. Battery calendar life is unknown but perhaps 20 years. It will be around a 220 lb. battery...still far less than lead-acid and twice the capacity.
