Motor Starter for 90 Heli - Build Thread

Another proposal to you.

Why not go for two of them in series and you gets 20V! this also can take FAST charge!

And it will be sure to be supported by the charger and provide better torque!

I have puchased the batt and the batt adapter,....can't change batteries now.

mechplas,
conult SKY. My hyperion don't seems to have LiIo selection also.

good luck

There's some differences between EOS1210i and EOS0610 DUO...

The EOS0610 DUO is a new generation of chargers which includes LiIon Charging at 3.6V/cell whereas the 1210i does not.

However further points to take note:

1) EOS1210i has discharge function
2) EOS0610 DUO has no discharge function at all

1) EOS1210i has no balancer built in
2) EOS0610 DUO has 2 x LBA10 balancers integrated! ( 1 in each port)


So, to each it's own...

Thanks

So it has to be the 0610iDuo.

Is it necessary to discharge Li-Ions?

Can I DIY an adaptor to the Makita battery balancing leads to the LBA10 integrated balancers?

Thanks Derrick!!

Mech,

Here s an extract from the full passage regarding Li-Ion :

" A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges...."

You can read more if you wish as it is quite a long passage.

Thing to note in their receommendation is that any Li-Ion cell should not exceed 4.2V for prolong cycle...

It is not required to balance but you MUST ensure each cell is matched before assembling them into a pack.

Ok. it doesn't sound to bad.

I'll call you when I am ready to meet up.

Thanks Derrick.

Looking at the charging table, the 18V ia made up of 10 Li-Ion cells. Does this mean each cell is 1.8v/cell?

I am worried that the 610iDuo cannot it.

I foresee a new Makita LXT Cordless drill set coming my way.....
