LiPo batteries are difficult to deal and maintain, Can I use Li-ion batteries?
I have been using Li-Po's for about 4 years on my drones. They work well and last a long time if you have a good balance charger. Just charge at 1C and be patient.As far as Li-ion I can't answer about the use in drones.Maybe somebody else will respond with that information.
I used a good balancer to charge but after flight battery got inflated.
Thanks for your response.
sounds like you ran the voltage too low.
All batteries age. They will puff up near the end of their life cycle (or a flight that abuses them). You can tell age by how much shorter your flight times are.
LiIon can only be used on highly efficient ships that draw less than about 2 amps per series (so 4S < 8 amps to hover). They seem to age better, but suffer the same problems as LiPo.
I'm guessing that LiIon will not work for you unless you are into ultra-light and lower speed. LiPo is probably best for you. Welcome to the variable (expendable) costs of flying quads.
I have a xcopter and I want to use general power tool battery in it instead of Custom LiPo. such as Milwakee M12.
If i did the math right, 9000 mah at 60 amps means a battery capable of 6.7 C. The Panasonic NCR18650B is rated to 2C. Are you using a different battery or are you saying that the Panasonic is under rated and can actually handle 6.7C?
Interesting, why there is no C rating for power tool batteries like Milwaukee M12 popular version?
