I was at the field today between 14:00 & 15:00 all on my own , good flying too. There is a dead sheep along the fence line towards the gate from the pits, I saw the farmer so reported this to her. I hope no one had plans for a BBQ Smile .

As mark says there's loads of ways to parallel charge.
This is how I charge my 2s blade 130x packs.

For most other packs I use this.

Not posted for a while, but logged on today...

Thats the lead I use It works for MCPX fine.

It is a serial lead so you have to charge 3 battery's at the same time.
The lipo charger has to be set to Balance charge at 3 cell charge rate
(The 3 mcpx battery's connected together via this lead turn is into one 3 cell battery (11.1volt)

Right at home now so I can use the laptop and type properly! Just ordered that lead from Fast Lad so should be here Friday so I can get them ready for Saturday. The batteries are Intellect 1S 250mAh 25c, so three of them will charge at 750mAh or .7a, at 1c? I'm using Overlander RC6S charger which should be more than capable of charging these.

If you connect battery's in parallel..the capacity increases (250+250+250 becomes a 1cell 750mah) so 1c = 750mah

If you connect is series the voltage increases and the capacity stays the same (250+250+250 becomes a 3cell with a 250mah capacity) so 1c = 250mah at 3cell charge rate.

Saying that on sat.. I charged my batts at 3c and all where ok. Some batts can handle upto 12c like thunder power.. I dont now how this will effect the life of battery.

If I am wrong some body correct me.

...so my charge rate would be 0.3a? At 3c that would go to 0.9a? Question

Yep thats my understanding.

The standard mcpx charger charges 1cell if I remember.. at 0.7 so you should be fine at 0.9 for all three on that lead.

But just ask one of the lads on sat. As nearly all have had more experience with lipo's than me but..its worked for me fine...

I've been really abusing those thunder power packs. Very Happy
Well when I say abusing I've been charging at 10c, not gone up to the rated 12c just in case.
At 10c they charge in around 10 mins for 6 in parallel. Good packs so far.

When weather gets better. I.e 2 weeks in june. I might treat my self to a couple for the 450. And could be on a constant cycle until I dirt nap the heli.... prob 4 flights lol

Ive heard lots of good about the Thunder power bats... and life cycle supposed to be second to none..
