40135 BATTERIES CASING (Powerbank, UPS)

40135 BATTERIES CASING (UPS, Powerstation, Powerbank, Charger, with BMS) 4-8 BATTERIES. 12-24V (20 000 mAh*24V = 100 000mAh*4.5v) (tested on EVE C40 40135)

The casing can be assembled with threaded studs (2*6mm studs) or using cable ties that is cheaper and more lightweight. Device can be assembled using the following elements: 1) 40135 threaded Batteries 4 or 8 items. (4 for 12v, 8 for 24v)

2) BMS: JIKONG BMS JK-BD4A8S6P 12V 24V

3) Power terminals:

4) 3* small switches 10*15mm (to turn on/off USB, Type-C, 24v to 12V chargers)

5) 1* switch 21*15mm (to switch power to lower device part)

6) Mini digital voltmeter (0.28 inch / 11*23mm)

7) 1*USB charger board (24v) (QC4.0 USB DC-DC Buck Converter Charging Step Down Module 10-32V to 3.8-12V Fast Quick Charge Circuit Board) OR PD3.0/PPS/QC4.0 DIY Fast Charger DC 10-30V 30W Step-down Module for Emergency Charging of Mobile Phone

8) 1*Type-C charger board (24v) (QC3.0 DIY Fast Charger Step-down Module USB Type-C DC 5- 32V 24W)

9) 1* or 2*DC LTC3780 DC-DC 5-32V to 1V-30V 10A Automatic Step Up Down Regulator Charging Module Power supply modul

10) Optional 1* 500W/250W 10A Step Up Power Supply DC 8.5V-48V to 10-50V Boost Converter Constant Voltage Current Drive Module Adjustable CC CV (for charging using 12v input)

11) 4 * Female DC Power plug 5.5 x 2.1MM 5.5*2.5MM 12V 24V Jack Adapter Connector Plug CCTV 5.5x2.1 2.5. Or analogs. Also you can buy 2*male connectors. You may need some malemale cable to make device work as UPS

12) 3.5 mm (outer diameter) nuts + M2 shorter and meduim bolts.

13) M3 screws (10mm)

14) M6 cable connectors *10 (for BMS) +2*for voltmeter.

15) 10mm2 power cable + 6*M6 to10mm2power cable connectors. (For battery to BMS and ports connection)

16) 2.5mm2 or 4mm2 + 2*M6 cable connectors (Connecting batteries to charging/discharging modules)

17) 2.5mm2 cable for modules connection.

Lower section is power thansformation & chargers section. Connect it through BMS! You can put chargers/dischargers there. You can put 12V in and 24V out (for UPS functionality) to back side. Set up 12V in to charge your battery with current and voltage needed (for example 27.4V). Use diode to make charger charging the battery but not to receive power from battery. Also you can connect diode to 24v to 12V frontal DC converter in to prevent wrong polarity issues. Holes for batteries are little bigger to prevent getting stuck, so you can use some insulating tape to increase battery diameter if needed. Alternative cap file is for support of the display with the battery level + power on/off button

Good luck!
