Good day

I am currently looking to set up a small solar pond pump with a rechargeable battery, so I can have the pond circulating for as long as possible. The position of the pond allows for sunlight access from sun up to sunset.

The materials I do have are as follows:
24 volt Solar panel
24 volt Lithium battery 6.8 amp hours at 2 amps
Small pond pump 4.8Watts, DC12v

I have looked over other posts, but have not found one with a Lithium Ion battery recharging included. I honestly am just unsure how to build the circuit. I would appreciate any help to understand how to build this correctly and efficiently.

Your problem is that lithium-ion needs a deadicated chip charger, so linear types are no good..
