I have this 2 s battery which came with my typhon grom.can i partially charge it with my basic charger that came with it.im a newbie to this hobby and whilst battery is not being used for a short time is is best to leave it flat,fully charged or partially charged.i know i probably need to invest in a better charger but not ready to buy charger until i know which charger to buy as i can see this hobby is addictive and looking to buy 4s/6s in future. Cheers all
