Here's the conversation from Bioenno power:
Hello,
We are having a discussion and hoping your company can add some clarification. If a li-po battery is purchased new, what is the best way to store it before it gets used?
Also, after a battery is used, what is the best method to store it long term?
Thank you

BP:The best way is to balance charge each of the batteries and store them at 50% of their capacity remaining. This can be achieved using a balance charger with status on it.
Me:Thank you for your reply.
Does this apply to new batteries before they are used?
BP:New batteries are usually provided at the 50% charge state. But if you wish you can certainly charge them up to full and then use the balance charger to bring them back down to the 50% state. Various balance chargers have that feature built in now where you can have it discharge down from full to 50%.
Me:So if I purchased a battery, and did not use it for 6 months, would the shipping charge be the best way to leave it?
BP:I would suggest cycling the battery every 6 weeks on the balance charger to maximize the lifespan and then have the charger set it back to the 50% for storage.
