Building A Better Excalibur Battery

[Chris W]

Tony, Gold Seeker pointed out in his post that I made a mistake in my post thinking you made your battery pack system some years a go. Sorry about my miss post I meant no disrespect. 

Tony and Joe, Thank you so much for the reply to my post and all the great information.

Tony in your battery pack system photos I do not see a circuit board but in Joe's photos I notice a circuit board. Do I need that circuit board to make up a battery pack and if I do what is the name of it?  

Also what make and model of batteries and battery holders do you recommend?

Tony and Joe, Thank you both again for all your help.

I use an off the shelf 3 x 18650 cell battery holder. The cells are protected Panasonic 18650 that I charge on an external battery charger. Probably the easiest setup there is. Joe has way more electrical know how than me and can safely build his own battery pack using an inline BMS for unprotected cells.

I use the same battery setup in my old Garrett Sea Hunter.

Fire away with any questions but I’ll leave the expertise with Joe for technical matters……especially with Lithium cells.

Just make sure that the battery holder is in Series and not in parallel.
