That's all.
I've been charging my flooded Marine battery (115Ah) using the default of 2.4v per cell (14.4v) at 10A. Would this be damaging to the battery? Do I need to lower the voltage to 2.3v per cell?

For me, 2.4/cell (14.4) is perfect for most flooded LA batteries in vehicles. I've measured a few alternator regulators, and ~14.4 is typical. Many AC powered chargers designed solely for automotive/marine LA batteries will run the voltage even higher (>15 volts) during charging. However, if this were a constant float/trickle charge situation, 14.4 would be too high and result in excess gassing over time. (Temperature also plays a part, cold batteries require higher charging voltage and vice versa.)

Julez or Junsi, I have a question. I bought a chargery 1010b. from reading this thread seems that both chargery & icharger might be different branding on the same or similar electronics.

I was wondering, can the chargery be upgraded the same way the icharger? with the same image as the icharger? I am experiencing a problem when discharging lipos... the amps start ramping up, and after around 30secs the charger beeps states the "system testing" and then shows the discharge screen while it freezes... it requires to unplug replug the charger to get it to work again.

Will a firmware upgrade fix de issue?

tks!

Thanks! I will be performing the upgrade to firmware 3.09 with a usb to ttl, that should work fine, i guess. I also read that you had to remove c52 (bottom left)... is this necessary, or would firmware 3.09 solve my problem?

Hello Sir,

You can try to upgrade it to 3.09 version by yourself.

Regards,
Junsi

Hello Sir,

You can remove c52. If you have some further questions, you can send email to harrief111@hotmail.com.

I found out that I get the best performance when I did not go higher than 13.8V.
Before I had the iCharger, and when I still used PB batterys, I just connected them directly with my 13.8V power supply.

But do a check yourself:
Charge to 13.8V, and then raise the voltage to 14.4V.
How much additional capacity do you get in?

I'll test it out and report back. Thanks.

Thanks for the Pb charging info guys. Really appreciate it. The more i can learn from experienced peoples about the unknown, the better! hehe

Seems very strange to me you would use a super expensive iCharger for lead/acid batteries.

I have used for years a very nice car battery fast charger from WalMart that cost only $45 or so. Also have a 1 amp trickle charger for storage use in the winter. Paid about $15 or so.

From what I have read about reliability problems on the iCharger I try to keep the use to a minimum on mine.

I tend to agree, though I do like that the iCharger line has Pb charging mode included. It could be handy in a pinch.

For my Pb batteries, I use a Battery Tender, which requires almost zero monitoring. I've had it for years, probably 16 years at this point, and it's always performed as expected.

Quick tip for possibly reviving Pb batteries that have been in storage. I have a couple of starter boxes for nitro buggies and such. Well, not so diligent maintenance of the batteries resulted in a couple of dead 7.2Ah SLA batts. Both iCharger's (1010b+ and 208B), and the Battery Tender, rejected them. Just out of curiosity sake, I connected one to an Ace Hobby DDVC (constant current, up to 10 NiCd or NiMh) and let it go for a bit. To my surprise, the voltage rose above 12V, so I then took it off and connected to the Battery Tender. Having a multitude of different chargers sure comes in handy!

I received the 106B+ and a few A123 cells; I will spend some interesting hours testing these.

The charger looks quite small for its capabilities. I hope it performs flawlessly.

It is a very fine performer, and very, very versatile. Which A123 cells did you buy: 1100 or 2300 mah?

I've worked with both, now, and prefer the 2300's, though the 1100 mah cells certainly have a place in my flying, too.
