SmallBMS for Smart LiFePO4 Batteries with M8
A simple and low-cost alternative to the VE.Bus BMS. The smallBMS can replace the VE.Bus BMS in several applications. It is however not suitable for use with VE.Bus MultiPlus and Quattro inverter/chargers: it has no VE.Bus interface.
The smallBMS is intended for use with Victron Smart LiFePo4 batteries with M8 circular connectors. The smallBMS has three outputs, similar to the VE.Bus BMS. Load Disconnect output The Load output is normally high and becomes free-floating in case of the cell under voltage (default 2,8V/cell, adjustable on the battery between 2,6V and 2,8V per cell). Maximum current: 1A. The Load output is not short-circuit protected.
The Load output can be used to control:
Pre-alarm output
The pre-alarm output is normally free-floating and becomes high in case of the imminent cell under voltage (default 3,1V/cell, adjustable on the battery between 2,85V and 3,15V per cell). Maximum current: 1A (not short circuit protected).
The minimum delay between pre-alarm and load disconnect is 30 seconds.
Charge disconnect output
The Charger output is normally high and becomes free-floating in case of imminent cell overvoltage or over-temperature. Maximum current: 10mA. The Charger output is not suitable to power an inductive load such as a relay coil.
The Charger output can be used to control:
System on/off input
The system on/off input controls both outputs. When off, both outputs will be free floating so that loads and chargers are turned off. The System on/off consists of two terminals: Remote L and Remote H. A remote on/off switch or relay contact can be connected between L and H. Alternatively, terminal H can be switched to battery plus, or terminal L can be switched to battery minus.
Protects 12V, 24V and 48V systems
Operating voltage range: 8 to 70V DC.

Arco A 275 alternator is almost a perfect fit on a yanmar 4jh3e. Installed with balmar pulley kit . Easy install and fast charging .n more belt dust covering everything.
3@405 watt rec panels on top of Bimini with 2@ Hyundai bifacials on top of Atlantic tower. 1x2 “ anodised aluminum used for supports . Each panel has their own mppt charge controller due to the amount of Shade on my sailboat.panels are providing a lot of power.
Instalation instructions where easy to follow.
The Zeus can be adjusted with the app to adjust the charging parameters.
Enclosed picture of gx device show a lot of solar going into batteries so the Zeus is providing enough amps to max out 300 amps going into batteries. If I was using more ac devices the alternator will increase output . Temperature sensor included with Zeus allows it to reduce output until alternator cools down.
Mabru air conditioner is great improvement from my old model. Cools boat down quickly. Easy install. I run this 17k unit of my 12/100/3000 ,victron invertor. Sometimes the solar panels will provide enough power for air conditioner ,2 fridges and all other loads.
Modular Rainman watermaker installed in separate locations. The motor and pump fit well under nav table seat ,membranes fit below forward bed. I made 80 gallons of water whilst motoring into port royal sound s.c. My victron 12/120/3000 invertor had no trouble running it .
The water produced was 200ppm. About the same as my city water filtered through Brita pitcher.
