Thermal protection option 1: battery with NTC
(1) if battery NTC is 10kohm; R1707=16.9K (+/-1%), R1708=27K (+/-1%)
(2) if battery NTC is 47kohm; R1707=61.9K (+/-1%), R1708=100K (+/-1%)
Thermal protection option 2: battery without NTC
(1) Deletc R334, R336
(2) Use R331, NTC301 for thermal protection
(NTC301 close to battery connector)
