ive been trying to figure out how many 18650 cells you can fit in a 12v 20ah SLA dementions.
Length: 7.13 inches (181mm)
Width: 3 inches (76.2 mm)
Height: 6.57 inches (167mm)
how many ah could I fit in these dementions assuming i am not including a bms and a base voltage of about 10-15v
i currently have 10 12v 20ah SLA batteries on my ebike. Each series connection has its own 12v charge port and charger when i need to balance the sla's. i flip the breaker and can charge that way or if they are within reason of one another i bulk charge with my 3a 120v sla charger.
i have a emmo xtron i basically used as a frame and body kit. did my thing and tore it apart and had a buddy help build a battey box that fits 10 12v 20ah batteries.. it was perfectly fine for the flat city life 90+ km range.. however I have moved up north here in canada and them steep hills and my heavy weight bike can only do about 40km before the batteries r near 100% discharged.. I'm looking to build some drop in replacement 18650 packs to run in series.
Can anyone give their input on how many ah i could cram in parelle and series that does not exceed each battery demention?
Brushless Controller: 120v 80a 36mos
