WTB: Looking for US Suppliers of LiFePO4 12.8V 20Ah SLA Replacement with BMS

[UberSteve]

Hi All,

Wondering if anyone can recommend a US supplier of LiFePO4 12.8V 20Ah (with BMS) batteries, that are a drop in replacement for your typical 12V 19-21Ah SLA (approx. 182x77x167mm)?

We've been testing one here in Aus (sells for ~USD $150),

(http://ev-power.com.au/webstore/12v-lifepo4-batteries/12v-lifepo4-batteries-with-bms/evh12v20ah.html)

but we surprisingly haven't been able to identify a US supplier for an equivalent price/performance product.

TIA!
