I’ve been looking around for a while and can’t find any 4.3v chargers for my Samsung ICR18650-28A.
I originally had my eye on chargers like the Turnigy Accucel 6 but am unsure if the termination voltage is adjustable to 4.3v. <—Anyone that has this charger care to check?
icharger does up to 4.30V in the general settings for LiPo End Voltage but not higher than that and it has nothing to do with calibration. you could download new firmware for higher LiPo End Voltages, i think Hillrc is working on it.
The Turnigy chargers do have a 'calibration' function, but it only goes +/-0.03v (0.06v total). Not enough adjustment range. If they would go +/-0.10v you could use the 4.20v LiPo setting for the 4.3v cells and the 4.10v LiIo setting for normal 4.2v cells, but it won't go that far. :(
I’d really spend the extra and get a Reaktor, You might find yourself wanting the extra features later on. But if you already have a charger you could try making a 4.3v top up charger like some did here.
Of course.
It will charge basically anything: Pb, NiCd, NiMH, Lithium (all chemistries up to 4.3V, not 4.35V, but that’s close enough for me).
Heck, it could even charge your 12V batteries at 20A. Much higher than any lead acid battery charger you could get in an auto shop for this price!
There are two downsides to this charger:
1- You need to get your own power supply to power it. You can buy one but a 300W capable PSU is at least 50 bucks. Or you can salvage an old computer PSU for that. Just keep in mind that you need 18V input to get the full 300W output. If input is 12V you’ll get about 220W output.
2- No stock!
If you don’t need 300W power and that charging at 4.2V is enough (no 4.3V batteries), then the Accucel 6 is also an excellent choice for a third of the price of the Reaktor. I have it and I’m very happy with it. I’ll buy the Reaktor for:
1- PC data logging
2- 300W
3- regenerative discharge
There is a new charger out on hobbyking for the new 4.3V lipo check this out.
I would recommend on buying a higher power version because of the discharge function. The charging power is more than enough even on the small models but discharge is limited to 1A max.
