Hello GobalPower,

when charging my battery GPRP280L231127R2601 with my victron MultiPlus 2-48-5000. I observe
- low charge current of appr. 14.8-20.0A
- differnt voltages messeared by MP2 & mulitmeter (55.22V) vs. BMS and Heltec Balancer (53.78V)

CCL is 140A
CVL is 55.2V

DC connection is: MP2 -70mm2-> Lynx -provided cables -> GP-SR1-PC200

I measured the voltage (55,22V) using two multimeter devices at both connections of the battery pack. Consequently, the difference must be within the battery pack or BMS and Heltec must be off by saem amout - they differe by appr. 5-10mA compared to 53V, though neglegtible.

What do you need from me to help me?

BR, Bjoern

- differnt voltages messeared by MP2 & mulitmeter (55.22V) vs. BMS and Heltec Balancer (53.78V)
at this moment, is the battery charging? if so what is the charge current, please?

Usually, inverter side voltage is higher than battery side voltage while charging, if the difference is too large, please check:
1. If 700mm2 cabe connected well with battery.
2. if screws for thick cables inside the battery loosen.
