Can I series connect the ePOWER B-TEC lithium batteries?
The short answer is no. Early failure of the battery pack is virtually guaranteed due to the mismatch in cell capacities.
Interesting. Can't say I've heard that before. Could this be endemic to just those batteries?
Available in 12v 100Ah & 125Ah capacities, the ePOWER B-TEC is designed and intended for use in deep cycle applications where a single battery is required that meets the amp hour capacity.
Now there's the clincher. Haven't found a price yet.
