18650 3S8P rack

Made these for my portable power box. Two of these glued together fill the bottom row in a plano ammo box. Gives 3S16P average about 35Ah with 2.2mah 18650's. My box holds two in parallel on bottom layer. Works great with this BMS Module. https://www.ebay.com/itm/3S-25A-12V-BMS-18650-Li-ion-Lithium-Battery-Lipo-Charging-Protection-Board-TE910/312123044794?hash=item48abfbb3ba:g:TTkAAOSwkRha6P~l
