Hi guys,
I have a powered paragliders with a 200cc 2 stroke single cylinder engine.
The unit uses a 16.8 volt system and has 14 Nicads (sub C 1700mah)
It is electric start and also charged the Nicad batteries whilst motor is running.
The existing batteries are soldered together in series, however after about 130 hours they have developed a memory And cycling them has not worked (perhaps I should have done this more often).
I decided to change over to Nimh batteries (3300mah sub C).
After making up the battery pack, charging batteries, and installing into paramotor, it barely turns the motor over.
I am not sure but I have another paramotor with a 12 volt lithium battery...an auto electrician said they draw a lot of amperage when starting.
How can I determine how many amps the paramotor electric starter needs from batteries when cranking?
Has anyone any experience with Nimh vs Nicad for this kind of application?
Do I have to go back to Nicads for electric start use?
