EM3EV 52v 21Ah Premium Triangle Frame Battery
EM3ev were 1 of the originators of the Triangle battery for Ebikes. These premium Triangle Packs are built using grade A Samsung and LG cells. Details of the performance to expect and our recommendations are detailed in the table further down this listing.
Combined with our triangle bags, even a small frame, possibly even a full suspension frame, can accomodate our compact triangle pack within the triangle of the frame. The battery weight (spec. dependent, approx. 4.2kg) when located within the frame triangle, is barely noticed. So, if you need compact size and high power, the 30Q are the best choices. If you also want to have the highest possible capacity, combined with high power, the MJ1 pack is the best choice. The charger included with these packs is a Alloy Case switching charger (50%, 80%, 100%) with a fan.
- Tightly packed triangle layout, with lots of protection to avoid damage. Heavy Duty Rubberised Heat-Shrink provides a tough and durable finish.
- 14S (50.4V, based on 14*3.6V) so that means a working voltage of over 48V most of the time and it also means that you’re getting that much more capacity than you would have had with an equivalent 13S Pack (7.7% additional capacity versus a 13S equivalent).
- PPTC thermal fuses used on all signal wires. If a fault were to ever occur on any of the small balance wires which run around the battery pack, the PPTC fuse simply shuts down the connection and keeps everything safe. Once the fault condition is removed, function returns to normal.
- Dimensions: ~75mm thick. 275mm long, 170mm high (detailed dimensions shown in additional images).
