lipo question

[slipknot666]

hi guys just a quick question about lipos. can you leave them in a charged state for any length of time? or should i be discharging them when ive finished?
cheers

As far as i know 50-60% charge is the best way to store them, you can leave them fully charged but this is ment to reduce the lifespan of the cells more than at 50/60% .

Saying that, If i happen to end up with a fully charged pack i just leave it charged and havnt noticed any negative effects

It's a myth that storing a fully charged LiPO makes any discernable difference. More as a selling point for chargers' discharge ability in my opinion.

if its a myth why would manufactures ship them not fully charged?

It depends on how long the 'length of time' is. If it is only a month or two, it would be fine, however, after being made, a manufacturer has no idea how long it will be before the LiPO is first used - it could be a couple of years before it is even sold to the end customer. At this kind of time period, then it will of course make a difference, but this isn't the length of time most people are talking about, it is usually only around a month or so.

Hello,
I'm thinking of changing from Nimh to Lipo's-ive got an Orion clubman lipo charger,what Lipo would you guys recommend for my B4-i'm running a 19t brushed motor????

[stampede vxlboy]

trakpower and go brushless if not using brushed motor you will need a lipo cut off switch

[samd]

Have a look on ebay at intellect lipos from china - i have some and are the same as demon lipos at a much lower cost, or as vxl says trakpower are good if you want to pay a bit more

Thanks guys,what brushless set up would you suggest?

[stampede vxlboy]

lrp or speed passion £129 for the esc and £69 for the motor i would buy a 6.5turn or 8.5turn

[Marvin]

For a 19T brushed equivalent? That'd be a 10.5T brushless motor.

I'd go with either a Tekin RS (the non-pro version), if you can afford it, or a Speed Passion GT2.0, for a more reasonably priced set-up.

The Tekin is useful in classes where 'slower' motors are used (10.5 or 13.5), as it has a boost setting, where the motor's timing is increased after about half throttle/revs, which makes it look a little like it has two gears, and can really give you an edge.
