Charger for 21700

Thanks HKJ vidramon that :+1:

Just charge, or do all the analytical foo-fa?

For just charging, worse comes to worse, a Folomov A1. Magnetic snap-thingies that’ll charge one cell in a pinch, regardless of the length (within reason).

Otherwise, any charger that’ll hold a fat 26650, and fit a long protected panny-B (longest beasties I know of).

The C4-12 should be fine. MiBoxer claims their charger is suitable for the new cells. Costs would be around $ 30 - 40.

Unprotected 21700 is fine. Acebeam 5100 mAh doesn’t fit.

Same goes for the Lii-500 and Esyb E4.

@RaVeN

The SkyRC MC3000 should fit 21700 right?

Unprotected 21700 is fine. Protected button top Acebeam 5100mAh doesn’t really fit but still makes contact and is able to charge.

21700 will NOT fit rc 3000.
i just got acebeam h30 headlamp, and the battery is too big to fit
its 5100 mah 21700 button top

I test in couple of chargers, but 20700 battery, the length is the same so no problem in that way.

From left to right : Samsung 30Q, Protected Xtar 18650, Sanyo 20700.

Protected 18650 :

Sanyo 20700 :

Lii 100 - no fit
Lii 202 - will fit very very barely ( I do not recommend ! )
Lii PL4 - will fit without no problems
Lii 500 - will fit without no problems
Zanflare C4 - will fit without no problem ( less space stays than on Lii 500 and Lii PL4 )

I have more chargers but they are 500mA max and I don’t test in them since this is slow charge for this kind of cells.

lii-500 with lii-40A 21700 70.4 mm long - can be loaded but it is very tight, so strained until it causes small dents in the cell, I do not recommend

lii-500 with sofirn 21700 4000mAh 70.7mm length - you do not put in the charger, it is too long

[Blggg]

I have Xtar MC1S and it can accept Lishen 21700, which is 71mm long, just fine (with about 0.5-1 mm to spare), but it won’t accept protected cells. Xtar is also having PB2S coming out.

The Xtar SC1 (2 Amps) charger will fit protected 21700 (tested the Rofis protected 5000mAh 21700 and Wuben 4800mAh protected 21700), no problems fitting in that single-slot charger.

Psst!

LiitoKala Lii-40A cells (Lishen LS21700-SA).

Files exist for reasons.

More updates from Liitokala regarding their Lii-202 and Lii-402 models:

Lii-202 and Lii-402 will change

Lii-202 and Lii-402 will change

The new Lii-402 and the new Lii-202 charger will be available from April. Production of the old Lii-402 and Lii-202 charger will cease.
The new charger will continue the old charger function. Just make the size bigger. The battery compartment was changed from the original 72mm to 76mm. The overall length has been changed from the original 112mm to 116mm. The width and height are the same.
This change is for a better fit for the 21700 battery.

Thank you for your attention.

I wonder when the new models will be available. Most likely, online shops are still getting rid of the older batches… If someone already manages to get hold of the extended-length Lii-202 and Lii-402, maybe inform us.

My new cells, do not fit in my Li-500 Charger
Purple Shockli 21700 4550mAh High Drain 30A Flat Top.

My Xtar MC1+ accepts it without any problem, but is single cell only.

What charger do you recommend?

[Flying_Luminosity]

Sofirn 21700 fits into the Liitokala Lii-S2 pretty easily, but is too long for the Nitecore D2.

[Yokiamy]

Quite strange actually, the type directs the dimensions of the cell, and still there are all kinds of varieties in dimensions of cells and flashlights where they do or don’t fit.

Standardisation…
