Dromon Bicycles custom ebike conversions. We assemble our packs using only proven high grade Li ion cells from Panasonic and LG . At the same time the electronics that we use for the Battery Managment System (BMS) are fully programmable and include thermal monitoring and protection. This allows us not only to adjust the protection parameters (i.e over current , undervoltage, cell ballancing etc) but also to set the operating envelope of the battery within certain limits that is proven to increase the cycle life of the pack substancially. We have the capacity to design and build on order battery packs from typical sizes (36-48V) up to high power High capacity battery packs (over 60V nominal over 50 amp continuous discharge over 20 Ah Capacity) for long endurance.
