I suggest take them off once they get full bars; plenty of people reporting instances of over charging and possible degradation of LiPo batteries (stacked pouch batteries; dewalt powerstacks and powerpacks) possibly due to failed cutoff, heat soak, parasitic drain ~1.5mA and or microcycling with the USB chargers. These new powerpack/stacks have a steep voltage curve drop off so they can be pushed into a deep discharge state once you use the remaining power at the lower end of the battery capacity per charge cycle.
There are no dewalt chargers that have battery balancing in their BMS so its best to not deep discharge them or else there is a high probability that it can lead to significant unbalanced battery which will significantly lower the battery's lifespan.
Another tip regarding powerstacks, the 'pouch battery' types do not typically produce a voltage sag where they give you a warning where the tool slows down and seem sluggish when the battery is low. These batteries have a voltage cliff, per se, where they give you high output then drop below 3V, sometimes below 2.5V gimping the battery and refusing a charge which is why you generally need to charge them after after they hit 1 bar because there will be no warning.
Fun fact: I'm using my DCB094 with a PowerStack right now.

Colloquially, yes they are lithium-polymer cells. All LiPOs are Lithium-Ion but not all lithium-ion are "LiPos". Lithium-Polymer is just a marketing term because all Li-ion cells can use polymer separator.
So, yes, Dewalt uses Li-ion cells using a blend or variant of NMC/NCA and in a pouch presentation (nickel manganese cobalt/nickel cobalt aluminum oxide as the cathode.) Due to the RC world, many people associate Li-ion cells in a pouch format as LiPos, so when people talk about Li-ion cells in that format, they are referring to LiPos. LiPos are pouch gel or a very low viscosity gel almost liquid like, in engineering we think them as having the same chemistry but different architecture with the main difference being pouch gel/low vis liquid vs cylindrical (liquid electrolytes) and BOTH have polymer separation.
"lithium-polymers" which is a marketing term because the polymer separator is not a unique characteristic considering cylindrical cells use polymer separators (polyethylene or polypropylene), pouches use PE/PP film so distinguishing it from the polymer film is meaningless and if you want to get into the history, all LiPos and standard cylindrical cells use liquid solvent electrolytes and not solid/dry polymer electrolyte. Dewalts pouch cells are arranged in a pouch form factor and thats basically the only real difference but the result of that lowers resistance/high output but voltage cliff effect vs voltage sag. So when we are talking about "LiPos" people are merely referring to the pouch format of Li-ion cells. LTO, LiFePO4, LiCoO2, LiMn2, etc can all have a pouch format.
RC "LiPos" generally use LCO while Dewalt uses the LiPo form factor using a NMC/NCA cathode in their powerstacks. Dewalt uses the language, "Lithium-Ion Pouch Cells" with very low viscosity gel/liquid with its DCBP034 in the 5S1P configuration,
Li-ion cells either cylindrical, pouch or prismatic should not be kept fully charged for long periods of time, charged within certain temp and discharged over a longer period of time and constrained against expansion.
PowerStack:
20V MAX XR POWERSTACK (DCBP = Dewalt Cordless Battery Pouch)
DCBP034 1.7Ah (5S1P config / 5 series 1 parallel stack)
