Lithium can be charged at any time, and very quickly if you choose to. You could quite easily get home from golf, plug in a 20A charger and put 20Ah back into the battery each hour. So you may not need such a big battery.

DIYing a battery is certainly an option and is rewarding and will save you money. Do you own and know how to use a multimeter? If the answer to that is yes, then go for it, if it’s no, then forget it as a lithium battery is not the place to teach yourself.
