... Battery Day
Lousy and wet outside, decided to post pictures to help dedicate my energies to finish some of my long delayed battery builds.
2 x 25.9V 26.4Ah (7s12p) with new Samsung ICR18650-22p 2200mAh cells
Dedicated for use with 1 eZip OEM LiFePO4 with 20A controller
eZip with 28A replacement controller
BMS units rated at 25A continuous and 50A cutoff, so hopefully adequate.
Selling 2 old eZips, with new battery builds. Will instruct new owners on battery care but adding the protection modules cause some people are ... seem, belligerently ignorant! (My own brother has been running his Lithium powered phone, tablet and laptop till cutoff, thinking it helps something)
I have been reluctant to build eBike batteries for others, only 1 so far, lives 2 blocks away, so adding, what I consider to be, a security blanket, to these builds.
33.3V 32Ah (9s12p) is for me, for use on Snow Beast, long trips (1kWh+) and 25mph cruising.
1 x 33.3V 32Ah with new Sanyo + Sony 2600mAh cells
Might replace red Sanyo with Samsung, with a loss of capacity but an increase in surge capability ... ? Will decide as I build the 25.9V batts.
25.9C 4.4Ah with 20A continuous >> 40A surge replacing 24V 1.4Ah NiCd
No room for BMS but will install balance leads-connector!
Got plenty of raw materials + 10 more 10s2p bricks
Well, too work now ...
