Default Battery Discharge current for Storage

Hello,

I have a fully charged 6000mah 7.6V LiPo, that I am using my Sky RC D100 changer to put in to Storage. What current should I select for storage discharge ?

Thanks

Alistair

Understood, but it's asking me for a current - not sure whether I should be going for 6A or lower

10A will be perfect. If you can't 6A is OK.

Mine has a default of 7.0A.

Usually 1C, so 6-7A would be fine. You can discharge at much lower current if you wish, it'll just take a bit longer.

What you will want to consider is rebound voltage as it relates to current and it depends on your discharger and how it stops the current flow.

For instance, on my 406duo, I can discharge at 40amps in storage mode and it will sit about 3.87 throughout the week with a cutoff of 3.85

If I use my sky RC 35 amp discharger, I'll get significantly more rebound in the voltage because it cuts off as soon as it touches 3.85. On the sky, if I am going to storage, I do 10 amps to slows the voltage crash down a bit.

A sensible charger will slow down the current draw as it approaches it's target for precisely this reason. Constant current until it hits the target voltage, then constant voltage until the current draw drops below a threshold.
