Count me in
i’m interested
in please
count me in for one.
This seems amazing, put me down for one
I’m interested in this charger, count with me.
In for one. Thank you!!
Would be interesting. How about real internal resistance measurement? How about tolerance for finish charging/discharging voltage? Especially I prefer finish voltage less than 4.2V, better 4.19 minus .05V .
I’m interrested in 1.
I like the display of the XTAR VC4S. It shows all information for all channels at the same time.
I also want two USB outputs for loading i-phone etc.
This reduces further power supply units.
Here are the additions since last week’s update and the BLF INTEREST LIST file linked to in post #1 have been updated too.
The interest list count now stands at 404 chargers.

Looks very nice!
One qestion, maybe it came up already, but I only see low voltage recovery for li-ion.
It is one of the things I dislike on the opus, when trying to recharge fully depleted NIMH I always need to “jump start” them in order to get recognised.
Will this problem be solved on the BLF charger? That alone is a good reason for purchase!
9V battery support would be another bonus.
@t-soung, sorry, but I won’t be including a second USB port on the design. Feature freeze has been done for a long time.
Upping the USB port current from 900mA to 1500mA would be an option however.
@Dutcheee, I do not think it is a good idea, but I’ll consider it a bit.
No 9V battery support, sorry. No more features to be added.
“No 9V battery support, sorry.”
Wait, what? How will I recharge my smoke-alarm batteries?!? And my AM/FM transistor radio batteries? Oh, the horror! 
Please add me to the interest list.
@ BlueswordM What is the reason not to be able to recover NIMH? Quite a few of my AAA’s are down to 0 when I recharge them. Even eneloops that have been charged once. They seem to work 100% after the recharge.
Would be a very nice addition IMHO!
For the 9V’s in my sons RC car remote I can live with These
I’ve been using NiMH AA and AAA batteries for decades, but I’ve never discharged any to 0V, so that’s pretty impressive . Perhaps…
1. Features on this charger are frozen, or at least gelled .
2. Recovery is actually somewhat difficult as it’s the battery chemistry is not obvious when the voltage is out of the normal range. Triggering a recovery mode manually would be desirable, but adds complexity to the user interface (I would like this option, as it avoids auto-detection and requires special knowledge).
I’ve occasionally had to recover NiMH cells, but it’s usually as simple as shorting the positive and negative terminals with a cell inserted. That tends to jump-start the charging process on my old LaCrosse charger BC-700, anyway.
Because that’s a good idea for NiCd cells, but not NiMH cells.
One way to remedy this would be to just let the cell in the charger until it accepts current, like how my Miboxer C4-12 does with old NiMH cells.
I would rather fix the devices that do this rather than counting on the charger to do so.
TLDR: Simpler can be better.
Put me in for 1
I recently found a very old NiMh (non-LSD type) battery in the drawer. It (very likely) has not been touched for at least 10 years. I recall using that battery when I had an old digicam (maybe around 2003 give or take a few years) that uses 4xAA batteries. So I use that type of non-LSD AA NiMh for that digicam. (Eneloops were not yet available when I used that digicam, although I recall the LSD “Harmolattice” NiMh started showing up a few years after that).
When I found that AA NiMh battery, it measured 0.0x voltage on my DMM (less than 0.1v), tried it on a few different chargers but they didn’t start charging the said NiMh.
So I tried doing a parallel connection from a good AA NiMh + side to + side of this 0-volt NiMh; - to - side to jump-start the “dead” NiMh battery, for several seconds. This was able to increase the voltage of the “dead” battery (I forgot what voltage, but I think it was now higher than 0.5v).
Placing it in my charger, I did a refresh test (charge/discharge at ~0.2 or 0.3A discharge current), and I got ~1100+ mAh discharged capacity (the AA NiMh was labeled GP 1800mAh NiMh). Tried using it in AA flashlights still work (Turbo mode is not that bright, indicating it has a bit higher resistance), but Low, Medium and some High modes will work. So far, it’s a month later, the battery still works. So apparently some dead AA non-LSD NiMh batteries can be recovered…
Interested!
