This is a side project from my 140p14s power wall project. This one is for camping power. Thought I'd put it up here.
Main use is power for ; camp lighting, power supply for 12-24v Engle fridge, 12v MinKota electric outboard motor for canoe and handheld device charging of phones cameras and torches.
Pack runs a Minkota 35 12v outboard for just on an hour on max throttle 5 which draws approx 30A
Each cell in the pack is 2300mah min capacity
Prototype unit is in a Pelican case and uses the 4 slot holders soldered back to back in 4s arrangement.
There is no cell Protection other Han what is arch cell has.
Charging at this stage is done by a hobby charger. I need a solar charger that can handle 50v in and programmable 16.8 out, Any suggestions?? I've tried the MPT 7210-A but it doesn't like that variance in input and battery voltage.
Connection is 50A Anderson plug and a 4s type balance lead.
Pictures show some fuses I had in for testing which have since been removed and unit now only has one fuse on while pack.
Pack is obviously a bit risky without cell fusing. Using these 4 slot ABS Battery box type of cell holders is risky with the end terminals able to cut through the end insulation and short the cell. Cells only go in and out negative terminal first.
Cells must all have very good condition wraps.
