This is a 52v battery designed to squeeze more power out of your stock 48 volt system without damaging your 48v controller or motor. To get more information read our article on 52 volt batteries.
Not only does the 52v battery give you more power, it also gives you more range than a comparable amp hour 48 volt battery. (read our story on calculating range)
Quality brand name 18650 cells utilizing the latest battery chemistry to get the highest possible power density. This means despite these packs small size and light weight, they will get you tons and tons of range.
Luna Mate builds its packs with the finest BMS (battery management system) available so that you can plug in your battery and not worry about over charging. Your cells are automatically balanced by the internal BMS in the battery. Our BMS includes such features as temperature over heat protection and advanced cell balancing. These features not only get the maximum performance out of your BMS they also keep your battery from getting to low, charging too high, or getting too hot and will automatically shut off your pack if it senses something is wrong.
Regarding Amps: These packs will easily put out 30amps (1500 watts) and even more for short bursts.
More than likely your controller is less than 30amps and then you don't have to worry since your controller will only take the amps from the battery what it needs. You cannot fry a controller by selecting a high performance battery with too many amps. Voltage however, you need to be careful with.
Regarding voltage: This is a 14s (52 volt) battery, which means it should be easily compatible with any 48v kit or ebike on the market no matter what the manufacturer might say (they would prefer that you pay more and buy only their batteries).
Most people mount this battery to the downtube of their frame (where the water bottle usually goes) but it’s very versatile where it can be mounted. Because it is so lightweight (7.5 pounds) it can also be used in a backpack.
This is a very easy to mount battery. It has a mounting bracket that will mount to most water bottle screw holes in the frame. If not you can drill threaded holes into your frame to accommodate it. Or you can use zip-ties etc. Once the bracket is installed it's a breeze to take the battery on and off. So you can have extra batteries that you carry on your ride that would easily fit in a backpack or on the racks on your bike.
For an independent review of this pack check out (this article) where Karl from electric-fatbike.com calls our shark the 'finest pack he has ever owned'.
The battery only just fit within my frame but the capacity is good. I did have to drill and tap some extra holes for it to mount to the frame in the correct location.
What to say? It's a great product, charge to 90% and it will last year's. Fast shipping, Great to deal with.
