DIY Ecotech Battery Backup (Pictures)

[m_t_r_86]

I made a compact battery backup for my two mp10s. I realize the battery I used is about a third the size of the Ecotech. As such, my two mp10s will run for a little more than 10 hours. I had space constraints and needed a smaller option than the Ecotech. I know this won't work for mp40s or mp60s the way I built it but given the right battery case and property battery size, the concept still applies.

Total price was $76.18 (includes sales tax and shipping)

My parts list consists of :
1. CURT 52022 6-Inch x 5-1/2-Inch x 3-1/4-Inch Lockable Trailer Breakaway Battery Case

2. Charity Battery 12V 5Ah CB1250 Rechargeable SLA Sealed Lead Acid Replacement Battery

5. 10pcs (5 Sets) 5 Positions Dual Row 600V 25A Screw Terminal Strip Blocks with Cover + 400V 25A 5 Positions Pre-Insulated Terminals Barrier Strip (Black & Red) by MILAPEAK

6. DZYDZR 2pcs 1 Meter 1.35mm x 3.5mm DC Extension Cable Black 22 AWG Copper Wire Male to Male Plug Max 24V 3A (3.3ft)

It was really easy to do. Drill some holes. Solder some connectors. Plug and play.
