Battery / Asset management

[Jumpy07]

I seem to have amassed a fair few batteries in eight months of this hobby..

2S/3S/4S & Nano versions...

Just wondering how everyone else manages their batteries.. ?

Do you number them, keep a tally of how many times they are charged, date of purchase, etc etc ?

What else is worth keeping a note of ?

These are the things that keep me awake at night lol

Well I';m a bit anal and i mark each battery with a Tippex pen with date of purchase - weight and a sequential number so I can identify batteries that are the same ...

Don';t log charges but do use them in numbered sequence ... :embarrassed :embarrassed

I keep a google docs spreadsheet of battery use.  I have to for the bnuc stuff but now that I';ve started it';s actually proving really useful, as I have calculated for example my mah per minute consumed, depending on weight being carried.

All mine are numbered but I dont bother recording dates or number of charges.

I used to have a little black book with all my cells in there when I was racing and used to record the amount it took to charge and discharge plus notes on how they felt on the track.
It worked and I always had my best cells for the important races and knew when some were getting past their best.
Took quite a lot of work to keep them all upto date.

Maybe I should do something a lit simpler for some of my flight packs to keep a eye on when they are getting tired.

What is it?

I worked mine out very roughly using a watt meter and my charger - I';m using about 120mAh a minute in a stationary hover, consuming about 100 watts of power (carbon fibre flyduino frame).

Unladen my big hexa is 374mah per minute.

With an additional 2kg';s weight I';m up to 1000mah per minute.  I know it sounds like a lot, but 2kg';s is a fair old chunk of additional weight to lug around.  I plan on having 10,000mah on board when I';m doing that sort of weight, although I suspect I';ll be flying with considerably less most of the time.
