3.200er batteries significantly more efficient than the new 3.400er

ThruNite offered so far only Flattop batteries to (black / silver). These were proven and had rightly a good reputation. Recently ThruNite offered a revised button-top version (red / white) in two versions, one with 3,400 mAh and 3,200 mAh rated capacity.

Actually the 3.400er batteries are based on Panasonic cells (NCR18650B) and therefore belong in theory to the more powerful batteries in the market. Unfortunately, a non-optimal PCB is apparently built which probably increases the internal resistance here.

In practice, this means that the battery voltage immediately above average breaks when used in a very power hungry lamp such as the NiteCore TM26 and the battery then reaches only very short maturities, and can not provide their full light output lamps. The nominal capacity of 3,400 mAh is achieved only with consumers to 0.5A. Even when consumers draw 3.0A discharge current, the actual capacity is only around 1,800 mAh. ThruNite advertises the battery but with possible discharge currents of up to 7,0A ...

Quite different is the more favorable 3.200er batteries. These are based (contrary to the manufacturer's instructions) to Panasonic cell type NCR18650BE. But it is built another, obviously better PCB. Here, the voltage drops under load is far less a, whereby longer maturities and higher light output can be achieved.

Otherwise, the batteries (3.200er and 3.400er) are very well made and fit easily in all lamps that I own.

For power-hungry as the lamps NiteCore TM26 or the ThruNite lamps TN36 or TN32 which ThruNite battery with 3,400 mAh are not recommended. Although they work "somehow" and bring the lamps also glow, but not for long and not even with the maximum power. In this respect, the application of the provider with discharge currents of up to 7A and suitability for high-performance flashlights is to question. The lamps of ThruNite I guess really, but of the house battery with 3,400 mAh should currently do not put your fingers.

The ThruNite batteries with 3,200 mAh, however, are quite recommendable. Especially there are almost the only protected batteries that fit easily in the TN32 and TN31 ThruNite. Almost all the other protected batteries are available in the diameter to thickness (or the battery tubes of TN32 and TN31 too tight).

The lack of high-current capability of 3.400er batteries has also been noted by experts and there are well-documented in relevant forums in accordance with tests.

Much better experiences I've done with the 3.400er batteries Keep Power, based also on Panasonic cells (NCR18650B), but have built a much better PCB. Interested in these batteries are also happen to be. However, this does not fit precisely in the TN32 and TN31, so I had to buy the ThruNite batteries. The 3.400er declined, 3.200er ordered following, however, are good and recommendable.

Conclusion: The revised version of 3.400er ThruNite batteries while looking "chic" of, technically but unfortunately a big step backwards. We can only hope that ThruNite can revise the PCB and in the future offering of these battery capacity to ThruNite luminous monsters as TN36 & Co. are also grown. Interested parties receive but with the 3.200er batteries ThruNite a significantly more powerful alternative and save compared to the 3.400er batteries even money.

Although two different products offered, it is not possible to review the batteries individually. I forgive 5 stars for 3.200er and 1 star for 3.400er batteries in the current version - ie a combined 3-star rating.
