« on: June 27, 2016, 11:28:23 am »I took a look at Stark Power and Smart Battery, and I'm not sure if they have a real system to balance cells either... Based on the pictures available on their websites it looks more like overvoltage/undervoltage/termal protection? Looks like they are building their batteries using many small cells, so if their battery comprises a few dozen of small cells (some connected in series, other connected in parallel), how much would the cost of complicated system to individually balance and maintain them?

Albert - on the Stark site they say:
"StarkPower “DEEP CYCLE” Models have a Battery Management System (BMS.) BMS monitors the key operational parameters during charging and discharging such as voltages, currents and internal temperatures.
There are three main objectives common to all Battery Management Systems (BMS):
Protect the cells in the battery from damage through overcharging or discharging too low.
Prolong the life of the battery with cell balancing.
Maintain the battery in a safe operating state."
This "BMS" or "no BMS" is an interesting discussion. On other RV forums I follow, it is always "must have BMS". Have never seen/read/heard the "no BMS" topic before. This discussion seems particular to forums/blogs on electric vehicles. Just wonder if the type of use/power demand for electric vehicles has anything to do with it. RV use is for lights, fans, fridge, run an inverter for some 120V appliance, etc.
