A small pack is only gonna be charged at 1 to 2 amps. The resistor could just be a small piece of nichrome or stainless steel wire. Stainless at 30 AWG would be about 0.25 ohms per inch. At 0.1 volts, that would be 40 mW of heat dissipation. Plus, at 4.1 volts, the pack will last much longer in cycles.

Protect lithium battery in parallel
$begingroup$ Because the intrinsic diode is in parallel with the FET. If you have two batteries connected the two FETs are turned on and there is a balancing current path available. The FETs short out the intrinsic diodes. So you have to put diodes in series with the battery to control battery to battery current. $endgroup$ –

Lithium Battery
Lithium battery are preferred in cold and extreme cold weather locations. AGM''s will have a poorer energy profile in cold weather (sub 20 Deg F) compared to a Lithium storage cell. Of course this is dependent on the battery chemistry, some Lithium chemistry''s do fair worse than an AGM in cold weather, not all things are made the same.
