How to charge a 3.2v 15.6ah power cell

[hunterstowe]

hello,

i just purchased 3 cree 1000 lumen led’s. I plan on making a 3000 lumen med. sized flashlight.

I have 6× 3.2v 2600mah li-ion rechargable batteries.
I made a 3.2v 15.6ah power cell with them.
I need help with figuring out how to charge the power cell.
The LED’s are 3v .700mah each, I believe

I saw a tenergy 3.2v intellegent 2a lithium charger
on a site but it was sold out.
will this work to safely charge my power cell?

can i buy a dc charger chip board or make one?
will a 3.7v safely charge my power cell?

need help, thank you

I attached a pic of the first flashlight i made
1000 lumen
3.2v 10.4ah
solar panel 200mah

on a full charge it would run 11+ hours at 1000 lumen
i need to charge it also

Good flashlight...

I am worried how you have connected the 3.2v lithium batteries to achieve 15.6Ah. Most probably in parallel, right?? If yes, then advising you to use the batteries and charge them in parallel condition will be not good. If you can charge the batteries individually then have a look at this.... https://www.qualitychinagoods.com/ultrafire-rapid-charger-32v37v-lithium-batteries-wf188-p-1710.html
