Question about 32600 "China special" batteries

[justinjja]

I got some 32600 batteries in,
Them seem to easily reach their rated capasity and beyond @ 1A (Measured them at 6050mAh)
Internal resistance is a little higher than i was hoping for, but not too bad about 150 mOhms.

They have no markings on them, and the site i bought them from doesnt list much in terms of specs.

So, my question what is a safe rate to charge these at?
and what is a safe rate to discharge them at?

I have used them in quite a few Saik hosts with dual flexdrives that pull anywhere from 2-3A without issues. I have always used my WF-188 charger but it only charges them @ 650mAh.


If you want a D sized cell that can really discharge @ high rates try these.

They did not blink discharging @ 9A for a LED build but they are not cheap.:beer:

At 3A they should be good for just about any laser application, so thats good.

Gosh at 650mA it must take nearly 10Hr to charge them

That is true but depends on how drained the battery is. 6000mAh takes a long time to run through @ 3A. That is two solid hours or 3 hours @ 2A.

According to Protected Single D Li-ion (32650/32600) [E4752] : Electronic Gadgets, Home Gifts & Unusual Novelty Gifts - BestOfferBuy, these can be charged from 0.2c-0.5c

I actually have the unprotected version on those cells, but surely they use the same cells,
so 2.5A charge rate it is

thanks
