Information on re-using the battery out of a "triplet" vehicle

Word of caution when buying batteries ⚠️

[!IMPORTANT]
The battery out of a triplet does not always contain the required parts needed for safe re-use of the battery. The early battery design (pre 2015), had the Battery Management Unit (BMU) located outside of the battery, under the rear left seat. The BMU tells the individual modules inside the battery when to perform cell balancing, and the BMU also calculates state of charge %, and measures how much energy is going in/out of the battery. So without the BMU, it is very hard to safely reuse the battery for stationary storage as-is.

If possible, try to source a 2016+ battery!

If you are using a 2015 and below battery with external BMU, try to also source the BMU from the same vehicle. No info on pinout exists yet.

Connection diagram

Here is a connection diagram of a 201#? battery: Connect the following wires to the LilyGo

• C26-10 CAN L - To LilyGo CAN L
• C26-5 CAN H - To LilyGo CAN H
• C22-4 to 12V+ supply
• C22-5 to GND for 12V

Handle precharge/contactors manually (no software support implemented yet). These pins are

• C22-7 Precharge
• C22-3 Positive contactor
• C22-6 Negative contactor

Example installation

From left, Solax X3 hybrid 15d inverter, in the middle LilyGo with dual can solution, on the right on the floor i-miev battery and the grey box contains 12V 4Ah battery relays to drive contactors and mitsubishi BMU (Battery is pre 2016, so external BMU mandatory).
