LIDL transmitter batteries (almost)

Post by Phil_G » 23 Jun 2019, 19:32

I've always wondered about the safety aspect of plastic-cased transmitters living indoors with their internal LiPo batteries. I'm a huge fan of the much-safer metal-cased, cylindrical 18650 size cells, and LIDL have a "Parkside" 2Ah, 21v Li-ion drill battery on offer for £12 at the moment. Its a 5S pack of good quality cells, ideal for making 2S tranny power packs. Its not difficult to dismantle the pack, harvest the cells then reassemble them into a couple of 2S batteries - and a spare :D
They're 4.2v charge so can be treated just like the usual 2S LiPo, and I've wired mine with a centre-tap, not to be truly authentic to the bad old days but to allow balance charging. You'll need a stardrive as apparently there are "no user serviceable parts inside". Wrong!

Good one Phil 8-)

For the true(?) Yorkshire men who don't want to part with their hard earned reddies, I've "re-purposed" many 18650's from cordless vacuums & laptop batteries that have suddenly failed, normally due to one dud cell. I always cycle every cell (after dis-assembly) at about 1A which gives plenty of margin over our uses in a Tx.

I then routinely monitor their capacity, as I do with all my packs (LiPo & Nimh). Doing this, I've not (yet) had a failure in service!
Cheers,

Wayne
