EM3EV 48v Frame Pack (13s4p Samsung 30q Cells)
This pack uses high powered cells and is the only 48v frame pack available that can comfortably handle discharge currents of over 25a (BBSHD, Mac Motors). Do not be fooled into buying high density frame packs (14Ah with GA or MJ1 cells) as
Em3ev battery packs include patented safety features that you will not find elsewhere. The stand out features are the facts that every single cell in the battery is fused and all the signal wires are also fused. This is in addition to the normal battery management system (BMS) that protects the battery against over-charge, excessive charge/discharge current and also balancing. The EM3EV Pack offers max charging current of ~8A (typically most other similar cases are limited to 3A charge rate).
EM3ev build battery packs and design/manufacture most of the key component in-house. EM3ev packs are always conservatively/accurately rated, which will help to ensure our packs provide a long and reliable service life.
The 48v DS5 pack (13S4P) is offered in this configuration with 30q cells. These cases are lockable, water resistant and have a USB charging outlet (for phone etc). There is also a simple battery level LED indication and the battery has a power switch which has an LED to indicate when power is on. This power switch does not pass the discharge current, it only switches the BMS output on/off. This means a Pre-charge is not necessary for this battery, and means the switch is not liable to failure, as is so common on packs that pass the discharge current through a switch.
