While they didn't think forward, you reap the benefits of a much cheaper system. Profoto's batteries for their 7B, B2 and B3 can either be lead acid or lithium ferrite (the latter being higher capacity and half the weight), the drawback being that the Profoto batteries are ~£400/700 respectively iirc as they include the charger circuitry into the battery casing whereas the Elinchrom batteries are only £100 each.Andy_BOne grumble that I do have about Elinchrom and this flash series is that if you want to move to the newer batteries you have to upgrade: The controller The connection leads The heads So - poor engineering on Elinchrom's part since they were unable to retain compatibility. Also a warning for those purchasing older units - there is an upgrade cost if you want to switch to the newer litihium batteries.
Worked fine, for me. The units have to be very old before a lot of things have to be changed, so I had an 'old' pack that worked fine with Li batteries, the leads were ok and the heads only cost £25 ea to make them compatible with either Lead or Li.Andy_B^^^[ While a change to the control unit/battery charger is fair game when a new battery technology comes along, the necessity to have interconnection leads/heads modified is unexpected and seems poorly thought out. Makes 'magpie1's suggestion to mix and match new and old units more difficult to follow.]
as far as I understand it's just the first batch of heads that need altering to work with the new batteries. it's £25 a head and there's a page of the flash centre site that tells you how to spot them. Apparently the fix is to replace a circuit board in the heads that is related to the modelling lamps. You can use a lithium ion battery with an old pack for powering other equipment such as ring flashes.magpie1Worked fine, for me.
