THE TRUE DIY TESLA RANGE EXTENDING BATTERY TRAILER

EV Channels Review

This video showcases a unique and functional DIY Tesla battery pack trailer, a stark contrast to the host's previous unpowered version. The reviewer is impressed by the ingenuity and practicality of the build, highlighting its potential for home energy storage and mobile power. The trailer utilizes a salvaged Toyota RAV4 EV battery pack, offering a historical perspective on Tesla's early collaborations. Key features include its parallel connection with the host vehicle's battery, a custom control box managing contactors and cooling, and a Raspberry Pi for data monitoring. While acknowledging the significant weight (around 1000 lbs with the trailer), the reviewer notes a surprisingly good highway efficiency of 3.4 miles/kWh. Concerns about safety and potential theft are addressed with physical locks and a GPS tracker. The build cost is estimated at around $7,000 ($6,000 for the battery, $1,000-$1,500 for the trailer), making it a cost-effective solution for extended range and power.
