LiPoly Charger - sku: PRT-00726

i am designing a circuit that is going to be powered from two li-poly batteries.

i want to integrate the two chargers into the circuit so i downloaded the schematic. when i got to designing, i found a component symbol that i’d never seen before. it is labeled SJ1, anyone know what it is and it’s value if applicable?

also, i want to use two, lithium polymer 6Ah batteries (sku: PRT-08484).

will the lipoly charger charge one of those three-packs?

“SJ1” is simply two solder pads that can be jumper-ed together with solder for a connection or cleared.

thanks

what happens when the “SJ1” is connected vs not connected?
