What is the difference between this and the arb-l21-5000?
Dianne (store manager) –
The 4000P is designed specifically for the higher settings and to maintain higher outputs more efficiently. Any of the batteries ending in a “P” are meant to be able to produce the higher power levels for a longer period of time.
