Not directly related to this thread, but on a 'similar' line from someone who has NIL understanding of electricity.
I start my trike mounted Rotax 503 with electric start, but to keep the battery size to an acceptable size and weight it is only 4 amps. This just about turns the motor when cold so to give a bit of ooomph when starting for the first time I add a jump start with a 7 amp LiPo. Th2 combinedd turns the motor really well so that I can warm it all up nicely. Then after attaching the trike to the wing (the engine still being warm) the 4 amp battery is quite sufficient. BUT, given that the engine is charging the battery while it is running, would I be able to fit the LiPo directly to the charging system of the engine and do away with the jump start?
I've kept away from this to date as I have no wish to start a fire at any time, never mind in the air. I have been told that a LiPo can be charged this way but obviously it isn't a balanced charging system when charged by the engine.
Any ideas?
