Small BMS link below. The VE Bus BMS mk2 has more features than you need so the Small BMS will suit and be cheaper if you can get it.
Also, the VE Bus BMS mk2 does not have a negative power connection, I forgot this earlier. It gets negative power from the Cat 5 VE Bus cable, there is a workaround on the site. The Small BMS does not have this issue.
Powering VE Bus BMS mk2 without Multiplus
I have the Lynx NG nice bit of kit but expensive for a small system. It has a continuous 0.3A power draw to consider. It comes with inbuilt battery monitor and contactor so is more complete.
Be aware, Victron are changing from Lithium Smart batteries to Lithium NG batteries, NG batteries need an NG BMS, older batteries without NG need a BMS without NG, they are not compatible.
