A note taken from the RadicalRC regarding fast charging of Sanyo's 2100mAh NIMH cells:
"This is Sanyo's latest high capacity AA. Unlike their other NiMH cells, these ultra high capacity cells should never be charged above C/2 or or about 1.1 amps on NiMH rated fast chargers. Of course standard C/10 or lower overnight charging is A-ok." Is your Sirius charger a "Pro Plus" or "Limited Edition"? The Plus model puts out a flat 1A per channel, and the LE model puts out a flat 2A per channel. Certainly enough to cook the batteries if the cells in the pack were a bit unbalanced. Capacitywise I use nothing over 1650 in an AA NIMH pack. If I need more capacity I use 2700 mAh A or 4000 mAh AU NIMH packs, as those tolerate repeated high-rate fast charging. -==- Barrett > -----Original Message----- > From: Brian Smith [mailto:[EMAIL PROTECTED] > Sent: Monday, November 08, 2004 1:56 PM > To: [EMAIL PROTECTED] > Subject: [RCSE] Battery food > > > Well, Battery Food for thought anyhow... > For the convenience of it I had assembled a couple > airborne packs from Wal-mart 2200 Nimh batteries..All was > well till I crashed my Wonderful Ava-Gea...Two of the cells > failed at the same time..They had been charged for a couple > months on a Sirius Smart charger..So I blame the cells and > not the charger... > My friend Jon Stone suggested he does/ I should use nothing > but sanyo batteries in my airborne packs..A couple months > later, so far so good...My 2 cents about off brand > batteries.."You pays your money/You takes your chances"...Brian Smith RCSE-List facilities provided by Model Airplane News.
