Hi everyone, David here from Central Coast NSW.
I run a web/email hosting&web design business during the day but am here to learn moreabout building 18650 packs.
Im 40ish now, but Im the past have completed electronics courses at TAFE, so know my way around a soldering iron and the basics of electronic theory. (Its been a while)
I have two projects planned..
1. Small battery pack for my kids 12v Quad bike. This will replace a12v -12ah lead acid battery. This is really just a fun / quick project to get used to testing cells and assembling them into packs.
I do need some advice on a BMS for such a pack. Im thinking of 4s and as many p as I can fit into the space. Probably 5 or 6p.
I can always charge this pack with my hobby charger - and can do it with balance leads. Maybe I dont need a bms?
2. Adecent size camping pack to power camping fridge, freezer, lights and phone chargers. Probably in the range of 200ah. I wont attempt this till I am familiar with how Im going to charge and maintain the beast.
There are a few camping threads on here but none really cover making a camping battery. Im thinking 4s but I will have 2x 160w (320w)solar panels that will need to charge this pack as well as being able to charge from the car alternator while driving. My current lead acid setup has amppt dc-dc charger but these are suitable for lead acid/agm batteries. Any advice heres would beappreciated. Somthing like a MPT-7210A - this device is only suitible for 24v packs and up thou.
Ill besure to post some picks of the packs during their build.
Thanks David
