I'm setting up this 60 ah LiFe pack, which will be used as a portable camping battery but I have a few questions.
Will be20 amp max draw. Using a 30 amp bms
These packs come compressed betweenaluminium plates and stainless straps. Thinking i'll remove this and heat shrink cells together to reduce weight.
When camping I will probably charge with 100 watt panel I already have.
I want to get a 240v wall charger for it also.
Q1. The bms I'm using has the through holes for soldering to. I was only able to fit 14 AWG wire through for negative.
Will this be enough seeing cable is only 30cm long? Or should I try and use 12 or 10 AWG.
Positive is 12 AWG with 20 amp fuse.
Q2.Cell specs say 1C maximum charging per cell, so think i'll get a 20 amp charger due to cable size. Will this be ok with cable size and length?
Q3. The bms has B- for negative to battery. Then P- and N- I have P- for charging and discharging currently butwould like seperate ports for charge/ discharge.
The question is, does it matter which one you assign to charge and discharge?
Q4.Could something like this work witha laptop charger for input?
