There is nothing to fix on the battery. Lithium batteries can be destroyed by discharging to zero. So how far is safe? That is a religious argument among engineers. But 80% is a generally accepted safe point. Down to 15% left is considered ok by a few. But that is the range. Never heard anyone arguing in favor of less than 15%.
The batteries are expensive and I for one want mine to last as long as possible. I'll just bring my external battery for longer distance.

1000 - 100 = 900 cycles left over 5 years very acceptable to me.
10-15% is more standard by the big brands too.
Trade offs that equal more fun, especially at cheaper DIY price, is worth it to some, others less so. 
I would be preserving that super expensive battery at all costs! Probably never dropping below 20% between charges. (Like I do with gas. Try not to drop below 1/4 tank to save my future fuel pump/line.). Plus, I will want it to get me to my next emtb riding destination (fun) for as long as the charging cycles can yield!
