Does the LiTime 48V ComFlex battery need a shunt to show on a Victron Cerbo GX?
What LiTime says it does with Victron
The LiTime 48V (51.2V) 100Ah Smart ComFlex is listed as plug and play with Victron. According to LiTime:
- No shunt needed. The battery's own data replaces a shunt reading.
- 25+ data points are synced to the Victron display, VRM portal or VictronConnect app.
- Charge control. Connected to a Victron (or LiTime) inverter-charger, its T5.0 BMS reports state of charge and temperature so the charging current adjusts automatically.
What you still need
A GX device for the battery to talk to. The Cerbo GX MK2 is Victron's system hub; it is what shows the battery on a display and passes data to VRM. You still need an inverter-charger for 48V, such as the MultiPlus 2000VA in its 48V version, and DC distribution with fusing, such as a Lynx Distributor.
The battery itself
| Spec (LiTime) | Value |
|---|---|
| Nominal voltage | 51.2V |
| Capacity | 100Ah, 5,120Wh |
| Parallel limit | up to 16 batteries with communication |
| Largest bank | 51.2V 1,600Ah, 81.92kWh |
LiTime also says its app can connect to any one battery in a communicating bank and see the whole system, rather than scanning batteries one by one.
Where a shunt still helps
If the bank also feeds DC loads that bypass the battery's own measurement, or you mix sources Victron cannot see, a shunt still gives a whole-system number. For a straightforward bank of ComFlex batteries on a Victron inverter-charger, LiTime's position is that you can leave it out.
