We aim to provide premium quality, long lasting, custom built smart ebike batterys.<\/span><\/p>\n

We provide, as far as we know, genuine facts and figures, along with free technical support.<\/span><\/p>\n

Each battery is made from genuine grade A Samsung high capacity 21700 cells.<\/span><\/p>\n

We only use 100% 10mm 0.2mm pure nickel strips for interconnecting the cells.<\/span><\/p>\n

We use space saving hexagonal cell holders to reduce the size of the batteries.<\/span><\/p>\n

Battery Nominal voltages can be configured to<\/span><\/p>\n

25.9V = 7S, 33.3V = 9S, 48.1V = 13S, 51.8V = 14S, 74.0V. = 20S
\n<\/span><\/p>\n

Battery Capacities can be configured to<\/span><\/p>\n

4P = 19.6Ah, 5P = 24.5Ah, 6P = 29.4Ah, 7P = 34.3Ah, 8P = 39.2Ah<\/span><\/p>\n

As an example a 13S7P battery would be 48.1V Nominal and have a max capacity of 34.3Ah.<\/span><\/p>\n

 <\/p>\n

The fully charged and fully discharged voltage of each battery can be custom programmed.<\/span><\/p>\n

For 25.9V batterys (24V)
\n<\/strong><\/span><\/p>\n

We reccomend charging to 28.7V (4.1V x 7), rather than 29.4V (4.2V x 7). We also reccomend discharging to 21.7V (3.1V x 7), rather than 17.5V (2.5V x 7), by doing this the BMS protects your speed controller before it hits its limit.<\/span><\/p>\n

Setting the max charge voltage at 28.7V will slightly reduce the top speed of your ebike, and very slightly reduce the capacity but will vastly improve your battery longevity.<\/span><\/p>\n

Setting the max discharge voltage at 21.7V will reduce the capacity of your battery, but will vastly improve your battery longevity.<\/span><\/p>\n

For 37V batterys (36V)
\n<\/strong><\/span><\/p>\n

We reccomend charging to 41.0V (4.1V x 10), rather than 42.0V (4.2V x 10). We also reccomend discharging to 31.0V (3.1V x 10), rather than 25V (2.5V x 10), by doing this the BMS protects your speed controller before it hits its limit.<\/span><\/p>\n

Setting the max charge voltage at 41.0V will slightly reduce the top speed of your ebike, and very slightly reduce the capacity but will vastly improve your battery longevity.<\/span><\/p>\n

Setting the max discharge voltage at 31.0V will reduce the capacity of your battery, but will vastly improve your battery longevity.<\/span><\/p>\n

For 48.1V batterys (48V)
\n<\/strong><\/span><\/p>\n

We reccomend charging to 53.3V (4.1V x 13), rather than 54.6V (4.2V x 13). We also reccomend discharging to 40.3V (3.1V x 13), rather than 32.5V (2.5V x 13). Most 48v KT style speed comtrollers have a cut off of 40V+-0.5V., so by doing this the BMS protects your speed controller before it hits its limit.
\n<\/span><\/p>\n

Setting the max charge voltage at 53.3V will slightly reduce the top speed of your ebike, and very slightly reduce the capacity but will vastly improve your battery longevity.
\n<\/span><\/p>\n

Setting the max discharge voltage at 40.3V will reduce the capacity of your battery, but will vastly improve your battery longevity.<\/span><\/p>\n

For 74.0V batterys (72V)
\n<\/strong><\/span><\/p>\n

We reccomend charging to 82V (4.1V x 20), rather than 84.0V (4.2V x 20). We also reccomend discharging to 62.0V (3.1V x 20), rather than 50.0V (2.5V x 20).<\/span><\/p>\n

Setting the max charge voltage at 82.0V will slightly reduce the top speed of your ebike, and very slightly reduce the capacity but will vastly improve your battery longevity.<\/span><\/p>\n

Setting the max discharge voltage at 62.0V will reduce the capacity of your battery, but will vastly improve your battery longevity.<\/span><\/p>\n

Using these voltages you can increase the longevity of your battery by a few years.<\/span><\/p>\n

 <\/p>\n

Custom BMS settings can be arranged pre sale.<\/strong><\/span><\/p>\n

Our recommended wattage is calculated by multiplying the nominal voltage by the constant current, For example for a Samsung 50E battery pack (13S5P), 48.1V x 49.0A = 2356W.

*Prices fluctuate due to cell prices and availbility, and are estimates only<\/span><\/p>\n

*Prices for other battery configurations on request
\n<\/span><\/p>\n

*Constant and peak current of battery are limited by the BMS settings, we dont push the cells too their max !<\/span><\/p>\n

*We use 60A bluetooth BMS modules, so maximum pack current is 60A constant<\/span><\/p>\n

*Battery max capacity is calculated by charging the cells to 4.2V, and down to 2.5V fully discharged.
\n<\/span><\/p>\n

*Usable capacity is calculated the charging cells to 4.1V fully charged to 3.1V fully discharged. <\/span><\/p>\n

 <\/p>\n

Battery chargers are designed to charge each cell to 4.2v (or max voltage the BMS is set to). <\/span><\/p>\n

To charge a 25.9V (24V) nominal battery (7S x 3.7V) , you need a 29.4V charger (7 x 4.2V).<\/span><\/p>\n

To charge a 37.0V (36V) nominal battery (10S x 3.7V) , you need a 42.0V charger (10 x 4.2V).<\/span><\/p>\n

To charge a 48.1V (48V) nominal battery (13S x 3.7V) , you need a 54.6V charger (13 x 4.2V).<\/span><\/p>\n

To charge a 74.0V (72V) nominal battery (20S x 3.7V) , you need a 84.0V charger (20 x 4.2V).<\/span><\/p>\n

 <\/p>\n

Charging<\/strong><\/span><\/p>\n

Samsung 50E standard charge rate per cell is 2.45A per cell, a 5P arrangement has a standard charge rate of 12.25A. Slower charging gives more capacity than standard rate charging, and slower charging extends the battery lifetime.<\/span><\/p>\n\n\n\n\n\n\n\n\n
