Thirty Six Volt 4P10S kit made of five 4P2S Blocs. With all BatteryBlocs you can disassemble the battery to repair it or to upgrade the cells.

Included is a 10S JST connector for a 10S hobby charger. There is an XT-90 for the power and charging connection, and a 30 amp blade fuse. The threaded rod is cut to fit. As in all BatteryBlocs, all the series connectors and electrical ring connectors are included.

You’ll need 40 cells. If you use these 2600 mah cells you will have a 10.4 amp hour battery of 375 watt hours. If you use these 3500 mah cells you will have a 14 amp hour battery of 504 watt hours.

The finished battery measures 3.8″ high, 3.25″ wide, and just under 9″ long. The two cell loggers pictured are no longer included as most people were not using them.  Assembly Instructions here.

You could use a 10S BMS for balancing:

Or you could charge and balance it with a 10S Hobby Charger:

 

 

You can use a smaller charger – like a common 6S hobby charger

but you will need to balance charge the battery in halves. You can read my ebook for wiring instructions.

Be aware that you will need a 12 volt power supply or battery to power the hobby charger- a server power supply works well:

 

You can build your own high powered charger using the above power supply and this boost converter. The charge voltage is adjustable- so you can undercharge your battery extending it’s life and it can adapt to your changing needs:

A simple Watt Meter is great for monitoring the battery:

    Hi
    Glad to see you introduced a line of complete kits, with overall lower prices. Convenience of kits is a great feature. Sorry to see you are not offering batteries any more. Not so convenient.
    Are you planning to adapt your line to the 20700 firnat?
    I would like to see some kits that addresses higher capacity/voltage ebike requirements.

      Hi Gordon,

      The Blocs are adaptable and I make kits for people on request. I make 21700, 20700 and 26650 Blocs too now. I ride a high voltage ebike so I get it. I’ll work on it.

    would love to see a 8p14s kit…

      Good idea. I’ll work on it. I can easily put together any custom kit that you can think of.
