do portable radios balance charge? (lemmy.ml)

I noticed a difference between my lithium Yaesu/Wouxun HTs battery packs and some Motorola part 90 units.

It looks like there are 3 contacts on the back of the ham radio packs (I think 1 is for sensing temperature?) and 4 on the Motorola packs. The Motorola packs are "smart" IMPRES batteries that go through a "conditioning" cycle periodically.

I feel pretty confident that the IMPRES packs are doing cell balancing, but I'm wondering if ham lithium batteries do the same. I'm pretty religious about keeping my Li-poly packs balanced, so am just curious how these are working.
