David Rodriguez replied to Blucraft's discussion Motor/Battery/Prop Combination Selection
"tried once but figured it was better to understand why select one battery, motor, prop. For starters if you want to use a standard 3S LiPo battery commonly used in F450 class copters you have to know your load so if you know the current draw of the…"

David Rodriguez replied to nickthecook's discussion How many batteries can I stick in a multicopter at once?
"You can attach as many batteries connected in parallel as you can lift. You just have to calculate the max Lift of your quad and then see how much batteries you can plug in parallel. I recomend you looking for high mAh rated batteries.

David Rodriguez replied to Fusion USA's discussion Double 4 cell vs double 3 cell LiPo's
"when you wire in series the current doesnt add only voltage does. if you wire it in parallel you get what I previously said. If you still dont undestand I recommend you to read Voltage divisor and current divisor in basic electricity books."

David Rodriguez replied to Fusion USA's discussion Double 4 cell vs double 3 cell LiPo's
"parallel wiring of option number 2 gives you double current and 11.1 volts which will give you more flight time

"if you dont have a problem with spanish you can find useful information here.

now if you dont no worries the lipo selection depends on the aplication or flight time you want, so for this you can use these equations:
Duration=mAh/maxCurrentLoad

David Rodriguez replied to Brandon Terrill's discussion Need some advice for my first build
"OK let me just help you out iwth the ESCs and battery part, first you need to know the maximum current draw of your settup, better explained is the sum of the current needed by every electric/electronic component you have, for instance if your motor…"
