lipo battery question.

-

i have project in mind require solar power , standby battery.
this largely charge sun device occasional wake , 100 ma power consumption.

my initial thought la ideal keep both mass , volume small.

my understanding if not cycled, lipos should periodically discharged.

for long time storage (float occasional use ?) charge level of 40 % recommended.
so should on size battery , charge 40% or stick la.

given cost of lipo best longevity, these batteries have seasonal use them last many years.


fyi it's related beehives.
 

voltage ?
mah ?

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
