How's the display brightness on the Xtar VC8?

The Efest LUC8 Dual Display had an issue of a very dim display with Efest saying they will fix it in the next version release.

Good, but it reduces it when you do not push the buttons or change batteries.

That Lii-S6 looks different to its Lii-S1 and Lii-S2 li-ion trickle charge blunder brethren; it also continues with the “any polarity” slot policy which in my opinion is superfluous. They're asking some money for an S6, hope it doesn't uses trickle charge with li-ion cells. 

It's cheap for sale at JIALANG INTL Store and will be cheapest at GlobalPower Co., LT Store once the incoming whatever AliExpress sale starts in 17+ hours from now on.

Please review the Hohm Tech Base 4 charger.
https://hohmtech.com/hohm-base/

I am particularly interested in its Battery Doctor feature, and how it works on NiMH cells (like AAs). Thanks…

Where do I but it without paying an arm and a leg in shipping?
US brands can be very expensive to get in Europe.

Just buy both that model and the Hohm Tech Base 4 charger at the same time — then at least the shipping is spread across two units. Wink

1) Xtar SC1

I was trying to find a review of the Xtar SC1 (the SC2 has been reviewed), but can’t seem to find it.

Just in case have time for a review. It’s a “li-ion only” charger that charges at only 2A, and supports 18650 size and higher (up to protected 21700). Was wondering if it’s an acceptably good charger.

2) Liitokala Lii-S6 (Li-Ion & NiMh charger)

Also checking if there’s a review of the Liitokala Lii-S6 (6-bay charger, no capacity test function). Wondering how well it is for charging Li-Ion & NiMh..

Just noticed a couple of new Liitokala chargers…

a) Lii-S8 (8-bay charger), specs indicate max 8× 1A or 4× 2A charging (+ 9v NiMh charging)

b) Lii-600 (4-bay analyzing charger), max 4× 3A charging, adjustable current with a low of 0.25A, and now restores resistance reading (the ‘updated’ Lii-500S didn’t have the ‘mR’ resistance reading of the earlier Lii-500 Engr [although the Lii-500 Engr’s mR reading is very inconsistent and nearly worthless; I hope they can get it right on the Lii-600] ; plus also restored the lower charge current [the Lii-500 Engr has a minimum charge current of 0.3A, but the Lii-500S only has a low of 0.5A; so it’s good to see the Lii-600 add in the low charge current of 0.25A]. The Discharge current is now ‘upgraded’ up to 0.75A discharge current, which hopefully will test larger-capacity batteries like high-capacity 21700/26650 faster..

Have you reviewed the EBL D cell capable chargers?

EBL906 & 9008?

To measure internal resistance of a battery, voltage variation is measured between two points while the current flow changes. Resistance is then calculated by Ohm's law, R = ΔV / ΔI.

The “inconsistent” battery internal resistance reading of the Lii-500 is mainly a consequence of where the voltage is read. The voltage sensing points used are somewhere in the circuit board, close to the rails. Hence, the resistance being measured is that of the rail plus contacts plus battery, and not just the battery. The resistance of rails can vary wildly as they are repositioned, and is of similar order of magnitude to that of batteries; to add more fuel to the fire the very contacts also play a role. It also matters to know how the measurement is done: the charger injects a small current in the rails on startup (≈0.2A according to the graph below from HKJ's Lii-500 test; I was under the impression that it was a higher current). This means that if batteries are close to fully charged, i.e. if battery voltage is high enough, the resistance reading will straight fail because the charger cannot raise rail voltage above maximum charge voltage.

 

 

All I can say in this regard is that it is best to have than not. The resistance measurement is helpful to know if your rail contacts are clean and your battery properly settled in the rail. If my Lii-500 reads high on startup I disconnect, wiggle the batteries in the rails and power on again. Do this a few times to find the lowest rail readings.

Don't put too much hope in the resistance reading of the Lii-600. To really make a difference the voltage sensing points must be located right at the battery terminals. This implies a proper battery holder (like this or that).

I see you are linking to http://www.liito-kala.com/. That's not the only LiitoKala website, though. Check out http://liitokala.com.cn/, I remember this other site was up and running long ago, when Henrik reviewed the original PLB OEM wrapped INR26650-50A cells.

Aaaah! Crazy China. This people needs to see the light, they're legally and culturally outdated. They need to awaken, they need to discern between good and evil. Its crazy what they do in many aspects. North Korea too, by the way.

Hi HKJ!
Do you plan to test the new Liitokola Li600?
Would be interested to know how ist performs. The specs looks very promising.

HKJ, have you ever reviewed any of these budget wall charger brands? (even if not exact model, would be good to know if any are sketchy or good brands in general)

- Elecife
- Choetech
- Ugreen – i think this one is generally a good brand and have seen some reviews of other models from them by you that said they were OK/Good (but not great)
- Novtech

Please if someday you want, review the Lii-600

Thanks in advance!
